1 EE 462: Laboratory # 4 DC Power Supply Circuits Using Diodes by Dr. A.V. Radun Dr. K.D. Donohue (9/18/03) Department of Electrical and Computer Engineering University of Kentucky Lexington, KY Laboratory # 4 Prelab due at lab sessions September 30, October 1, and 2. Lab report due at lab sessions October 7, 8, and 9. I. Instructional Objectives Design and construct circuits that transform sinusoidal (AC) voltages into constant (DC) voltages. Design and construct a voltage regulator based on the characteristics of the Zener diode. Evaluate the performance of simple rectifier and regulator circuits. See Horenstein 4.3 and 4.4 II. Background Electric power transmits best over long distances at high voltages. Since P = I V, a larger voltage V implies a smaller current I for the same transmitted power. Smaller currents allow for the use of smaller wires with less loss. The high voltages used for power transmission, however, must be reduced to be compatible with the needs of most consumer and industrial electric equipment. This is done with transformers that only operate with AC (DC does not pass through a transformer). Since most electronic circuits require DC (constant) voltages, normal AC power voltage must be transformed into a DC (constant) voltage. The terminology "DC" is somewhat ambiguous. DC can mean the voltage or current always has the same polarity but changes with time (pulsating DC), or it can mean a constant value. In this lab assignment DC will refer to a constant voltage or current. If voltages or currents always have the same polarity, but change with time, it will be referred to as having both a DC and an AC component. The process of changing an AC signal that has both plus and minus values, to a signal with only plus values is called rectification, and circuits that perform this operation are called rectifier circuits. The rectifier circuit operates in a way similar to the clipping circuits used in a previous lab. Figure 1 a) shows a half wave rectifier and Fig. 1 b) shows a full wave rectifier.

2 (a) Fig. 1 a) Half wave rectifier. b) Full wave rectifier. (b) Although the output of a rectifier is always positive, (or always negative) it is generally not constant, often going from zero to a peak value. Thus, the output of the rectifier must be filtered to obtain a DC (constant) output. Since DC has a frequency of 0 Hz, a lowpass filter can be applied to attenuate the higher frequency signal components. The simplest low pass filter is a capacitor. Figure 2 shows examples of passing rectified signals through a lowpass filter. This lowpass filtering is sometimes called smoothing. No realtime filter can have a cutoff sharp enough to totally eliminate unwanted frequencies, so the actual output of the filter will always have some AC content, often called ripple (ripple voltage or ripple current). A rectifier combined with a filter forms a simple DC power supply. R L R L (a) Fig. 2 a) Half wave rectifier with capacitor filter. b) Full wave rectifier with capacitor filter. (b) One performance measure of a DC power supply is the percent output ripple computed from the ratio of the (peaktopeak) output voltage to the average (DC) output voltage. Output ripple can be expressed as r in the equation below: Vop p r = (1) Vo where Vop p is the peaktopeak output voltage and V o is the mean of the output voltage, which is equivalent to the DC component. Multiply r by 100 for percent output ripple. A typical output signal is illustrated in Fig. 3. The best performance occurs when the percent ripple is zero (a battery produces ideal DC). This lab examines and compares the two rectifier schemes in Fig. 2.

3 V o Vop p Peak to peak ripple Average DC V o t Fig. 3 Definition of percent ripple A DC power supply provides constant DC voltage to some load, which will be modeled as a resistor. This constant value should be independent of the load and fluctuations of input voltage. When a load is applied to a simple power supply output (as in Figs. 1 and 2), the output voltage decreases due to increased resistive voltage drops, diode voltage drops, and increased voltage ripple. A voltage regulator circuit is used to prevent this change in output voltage. A Zener diode can be used to make a voltage regulator circuit (see Fig 4) by taking advantages of the Zener diode s reverse breakdown characteristic. Recall that once a Zener diode breaks down, its voltage remains essentially constant independent of its reverse current. The regulator's resistor, Rreg, limits the current through the Zener to reduce the power dissipated in the Zener. This is done, however, at the price of limiting the maximum load current that can be supplied with a regulated output voltage. Vin Rreg Vout Fig. 4 Zener voltage regulator An important characteristic of a voltage regulator is its percent regulation defined as the difference between the average noload voltage (implies zero load current and thus infinite load resistance) and the average fullload voltage (the load draws its maximum current and has its minimum resistance) divided by the average fullload voltage. Regulation can be expressed in the equation below: VoNL VoFL Regulation = (2) VoFL

4 where VoNL is the average output noload voltage and V ofl is the average output fullload voltage. Percent regulation is obtained by multiplying Regulation in Eq. 2 by 100. The best regulation performance is achieved with a 0 % regulation. A typical DC power supply consists of 3 stages, which are a rectifier, a filter, and a voltage regulator. A power supply using this combination is shown in Fig. 5. Rreg Vs Vin Vout AC source Rectifier Filter Regulator Load DC Power Supply Fig. 5 Basic power supply consisting of a rectifier, filter and regulator. III. PreLaboratory Exercise 1. For the halfwave and fullwave rectifiers in Fig. 1, determine the output voltage and the current through a 5.1kΩ load with a sinusoidal, 8V rms, 60Hz input voltage. Use suitable approximations. 2. For the fullwave rectifier case, sketch a schematic showing how you will place your probes to measure the output voltage and briefly describe how you will measure this voltage. Grounding is the issue here, so clearly indicate where the grounds of probes are placed and the described the oscilloscope scope settings for viewing the waveform of interest. 3. For the filtered halfwave and fullwave rectifiers in Fig. 2 estimate the capacitor current, the output voltage, and the output current through a 5.1kΩ load with a sinusoidal, 8Vrms, 60 Hz input voltage. Select a capacitor value so that the output ripple voltage is 1V PP for the halfwave rectifier with a 5.1kΩ load. Use the same value of C for the fullwave rectifier. What is the full wave rectifier s ripple voltage? Use suitable approximations. What is the ripple voltage with no load ( R L = )? 4. If the calculated value of capacitance is not available in the lab, should one with a larger or smaller value be used? Explain your answer. 5. You plan to measure the current through the capacitor by placing a resistor in series with it. Therefore, the voltage across the resistor can be used to estimate the current through the capacitor. Choose a resistor value such that the ripple voltage added by the resistor is 0.25V PP for the half wave circuit. Use suitable approximations. 6. For the half wave rectifier case, sketch a schematic showing the currentsense resistor in series with the capacitor and how you would place the scope probes to simultaneously measure the capacitor voltage and the capacitor current. Grounding is the issue here, so clearly indicate where the grounds of probes are placed and the described the oscilloscope scope settings for viewing the waveform of interest.

5 7. Design a Zener voltage regulator to regulate the output of the filtered rectifier circuit to 5.1V (use a 5.1V Zener 1N751A or equivalent). Design the regulator so it can handle the maximum possible load (smallest possible R L ) while keeping the maximum Zener power at no load to 25mW. With this constraint, determine the maximum load (in Amps) that could be supplied while maintaining output voltage regulation. 8. How does the addition of the regulator change the ripple voltage across the circuit capacitor? 9. Simulate your completed power supply design using SPICE for the half wave rectifier case to verify it meets requirements. IV. Laboratory Exercise 1. Construct the half wave rectifier circuit in Fig. 1a. Set the input voltage to 8V rms and 60Hz. Record the output waveform. (Discussion: How does your measured results compare to your prelab calculations?) 2. Add a filter capacitor that is close to your prelab calculated value. You will need a polar capacitor to get the value you need so make sure you get the polarity correct. Small value capacitors tend to be nonpolar while large value capacitors tend to be polar. Record the output voltage waveform. (Discussion: How does this result compare to your prelab calculations?) 3. Measure the percent ripple of this circuit for noload and for a fullload equal to 5.1kΩ. 4. Add the voltage regulator of Fig. 4 to your circuit. Use the value of R reg you calculated in your prelab. Record the output voltage. 5. Make measurements and estimate the percent ripple of this circuit for noload and for a fullload equal to 5.1kΩ. 6. Make measurements and estimate the percent regulation of this circuit for a fullload of 5.1kΩ. 7. Construct the full wave rectifier in Fig. 1b. Repeat tasks 16 above. Be wary of grounding issues in your measurements! 8. Measure the percent regulation of the left most variable DC output channel of your lab power supply at an output voltage of 5.1V and with a 5.1kΩ resistive fullload. Record your results. (Discussion: How does the regulation of your power supply compare to the regulation of the laboratory power supply? Overall, compare the performances of the 2 power supplies.)
