1 Digital Combination of Buck and Boost Converters to Control a Positive Buck Boost Converter and Improve the Output Transients Shruthi Prabhu 1 1 Electrical & Electronics Department, VTU K.V.G College of Engineering, Sullia,India shruthi.prabhu.65@gmail.com Abstract. A highly efficient and novel control strategy for improving the transients in the output voltage of a dc dc positive buck boost converter, required for low-power portable electronic applications, is presented in this paper. The proposed control technique can regulate the output voltage for variable input voltage, which is higher, lower, or equal to the output voltage. There are several existing solutions to these problems, and selecting the best approach involves a trade-off among cost, efficiency, and output noise or ripple. In the proposed method, instead of instantaneous transition from buck to boost mode, intermediate combination modes consisting of several buck modes followed by several boost modes are utilized to distribute the voltage transients. Keywords: Buck boost converter, DC DC 1 Introduction A very common power-handling problem, especially for portable applications, powered by batteries such as cellular phones, personal digital assistants (PDAs), wireless and digital subscriber line (DSL) modems, and digital cameras, is the need to provide a regulated non inverting output voltage from a variable input battery voltage. The battery voltage, when charged or discharg ed, can be greater than, equal to, or less than the output voltage. But for such small-scale applications, it is very important to regulate the output voltage of the converter with high precision and performance. Thus, the criterions such as cost, efficiency, and o utput transients should be considered. A common power-handling issue for space-restrained applications powered by batteries is the regulation of the output voltage in the midrange of a variable input battery voltage. Some of the common examples are 3.3 V output with a V Li cell input, 5 V output with a V four-cell alkaline input, or a 12 V output with an 8 15 V lead acid battery input. With an input voltage range that is above and below the output voltage, the use of a buck or a boost conv erter can be ruled out unless cascaded. Cascaded combination of converters results in cascaded losses and costs; therefore, this approach is seldom used. In such a range of power demand, the transition of dc voltage from one level to another is generally accomplished by means of DC-DC power converter circuits, such as step-down (buck) or step-up (boost) converter circuits. There are various topologies such as inverting buck boost converters, single-ended primary inductance converters (SEPICs), Cuk converters, isolated buck boost converters, and cascaded buck and boost converters, which can be implemented to maintain a constant output voltage from a variable input voltage. 2 Existing Solutions 2.1 Demerits of Using an Ordinary Buck Boost Converter There are various issues about an ordinary buck boost converter, which prevents its use for such specific applications. The biggest problem associated with such a converter is that the output of such converter is inverted. Of course, it can be inver ted, but it requires a transformer, which adds to the cost and space and sacrifices the ef ficiency of the converter Canara Engineering College, Mangalore NJCIET
2 2.2 Disadvantages of a Cascaded Buck and Boost Converter Such a topology applies two DC DC converters cascaded together hence; the loss of the whole single converter is actually doubled in this case, which results in poor efficiency. The number of external components such as inductors, decoupling capacitors, and the compensation networks needed for both controllers in this case is more. Due to more components, more space is occupied, which results in higher cost. In addition, sub harmonic problem is another issue, which prevents utilizing cascaded converters. Fig. 1. Cascaded boost and buck converter. 3 Proposed New Method 3.1 Operation of positive buck boost converter The circuit topology of a positive buck boost converter is shown in Fig.2. In buck boost operating mode, always, two switches, Q1 and Q2, and two diodes, D1 and D2, are switching in the circuit. A positive buck boost converter can operate as a buck converter by controlling switch Q1 and diode D1, when Q2 is OFF and D2 is conducting. It can also work as a boost converter by controlling switch Q2 and diode D2, while Q1 is ON and D1 is not conducting. When the voltage of the battery is more than the output reference voltage, converter operates as a buck converter. As soon as the voltage of the battery drops to a value less than the output reference voltage, the converter should switch to boost mode. The added advantage of the converter is that the output of such a converter is always positive. Fig. 2. Circuit topology of a positive buck boost converter. 3.2 Digital combination of power converters Control approach based on DCPC improves the dynamic response of the converter during transients by switching between different converter topologies to spread out the voltage spikes that are an inevitable part of the transients. Fig. 3 demonstrates the block diagram of the proposed approach. Here converter topology control (CTC) controls the operating topologies of the converter. In addition, transition control (TC) units control the transitions between various topologies. For instance, TCi c ontrols the transition behaviour of the converter from the ith converting topology to the (i + 1)th topology. In the transition from ith topology to the (i + 1)th topology, instead of instantaneous transition from ith topology to (i + 1)th topology, for αi switc hing cycle, converter operates in ith topology and for βi switching cycle, it operates in the (i + 1)th topology. Operation with αi and βi switching cycles in transition mode will be repeated for γi times. For a specific case, where αi = mi, βi = 1 and γi = mi 1, in the transition from the ith topology to the (i + 1)th topology, for the mi switching cycle, the converter operates in ith topolog y and for one switching cycle, it switches to the (i + 1)th topology. Then, in the next cycle, TCi tries to increase the num ber of cycles Canara Engineering College, Mangalore NJCIET
3 of operation in the (i + 1)th topology and decrease the number o f cycles of operation in the i th topology. Then, in the next cycle, TCi tries to increase the number of cycles of operation in the (i + 1)th topology and decrease the number of c ycles of operation in the ith topology. Finally, before the complete transition to the (i + 1)th topology, for one switching period, it operates in the ith topology and, for mi switching cycle, it switches to the (i + 1)th topology. DCPC imposes the fact t hat the proposed converter topology should have the capability of operating in various converter topologies with only controlling the switching componen ts of the circuit.

In this method, the converter initially works in the buck mode, when the input voltage is greater than the output voltage, followed by the buck boost mode when the voltages are almost equal. Finally, the converter works in the boost mode when the input voltage is lower than the output voltage. The simulation results indicate a decrease in the presence of spikes in the output voltages.

And the output is viewed through a multi-meter. Input voltage is varied from 2V-7V.When input voltage is 3.6V then the PWM starts boosting.. As input voltage is increased the PWM starts bucking. So however when input voltage is increased or decreased the output voltage remains constant at 5.0V. Canara Engineering College, Mangalore NJCIET
7 6. Conclusion and Future scope This simulation presents a simple but efficient system. It models each component and simulates the system using MATLAB. Correct modeling of the DC-DC converter is an important area of study, and various difficulties remain in the current study. A more realistic model of the DC-DC converter would involve a diode loss, a switching loss in a Power-MOSFET, and resistive losses in inductors and capacitors. SimPower Systems provide components to build electric circuits in SIMULINK and allow including such losses. At the initial phase of simulation design, attempts to build Buck -Boost converters in SIMULINK faced unsolvable difficulties. Building the whole system in SIMULINK, however, could open avenues of study such as stability analysis of system and implementations of more advanced control methods. Hardware setup was done using positive buck-boost converter. The Buck-Boost converter is highly efficient and reduces the ripples in the output voltage Less labour and low maintenance cost. Non polluting to the environment. Easy to remove, transport and store. 6.1 Future Scope This project can also be carried out by implementing it to solar panel systems. Solar panel is used be cause it uses minimum energy and gives maximum output. In our project, we have used a 5V power supply for the PIC microcontroller. This is the main limitation. This can be eliminated by giving a feedback from the battery to a 5V regulator. Project can be a lso be modeled in various applications such as solar-wind hybrid power system, DC pump etc. References 1. A. Chakraborty, A. Khaligh, A. Emadi, and A.
