3 1 Introduction 1 Introduction The development of fully controlled power electronic converters has led to improvements in variable-frequency drive (VFD) performance and efficiency. Voltage-source converters (VSC) are a popular type of VFD that use power electronic switches and capacitive energy to emulate an alternating output voltage from a dc-link. Common VSC topologies use pulse-width modulation (PWM) with two output levels to achieve an alternating voltage with a desired magnitude and fundamental frequency. The concept of voltage-source conversion can be extended to produce a staircase waveform with multiple output voltage levels. The purpose of this project is to design and implement a small scale VFD using a multi-level VSC topology. Multi-level converters have shown several advantages compared to conventional two-level VSCs. Benefits such as improved output waveform quality, reduced switching frequency, and lower levels of produced interference have been demonstrated[1]. The converter topology to be designed is the modular multi-level converter (MMC) [2, 3]. The MMC will be used for its scalability and simplicity of topology compared to the other multi-level converters. The MMC allows for increasing output levels by adding identical sub-modules (SM)[3] which can reduce switch and capacitor voltage ratings and improve harmonic performance. This project will contribute to the practical application of the MMC as it is a relatively new topology that has grown in popularity over the past few years. 2 Project Details This section gives specific details of how the project will be implemented, as well as the system components needed to meet project objectives
4 2 Project Details 2.1 Implementation A basic version of the converter will first be implemented by testing a single SM. Sub-modules will then be cascaded and their individual control will be tested. Half-bridge SMs will be used because they allow for simpler control schemes and fewer components compared to full-bridge SMs. The control system will be simultaneously developed as the circuit complexity and functionality increases. Real-Time Digital Simulator (RTDS) will be used to simulate firing-pulses to allow for independent development of the control system if required. The MMC and control system will be integrated and used to drive an induction motor with open-loop controls upon successful test results. The performance of the converter will be tested under various load conditions which can be set by a dynamometer. The system overview is shown in Figure 1.

5 2 Project Details 2.2 Topology Description In steady state, the converter operates by switching SMs in the upper and lower valve (denoted UV and LV on Figure 1) such that the potential v ac in between them is alternating as described in equation 1. v ac = v l v u 2 L arm 2 di ac dt (1) If there are N SM capacitors C inserted in the converter at all times, then their nominal voltages should be the same at V dc /N. As current is drawn from the converter, the voltage in each SM capacitor changes. The arm inductors L arm are used to limit unwanted harmonics in current deriving from the voltage imbalance between the dc-link voltage V dc and the sum of the upper and lower valve voltages. Balanced capacitor voltages will result in minimal deviation from a staircase waveform and reduced harmonic content in the arm currents [4]. 2.3 Simulation A simulation case will be developed as the project progresses to ensure that the design choices made are met. Power systems CAD (PSCAD/EMTDC) will be used to simulate a high-level representation of the circuit topology and control system with the goal of accurately reflecting the designed system. A key part of the converter simulation is to aid in component selection decisions. 2.4 Component Values Selection The components in the MMC circuit to be selected are the sub-module switches and capacitors, dc-link capacitors, and arm inductors. The voltage ratings of the components depend on the dc-link voltage and the number of active SMs in the converter. The dc-link capacitors will be selected to allow for an acceptable sag in voltage. The SM capacitor and arm inductor will be chosen based on equations developed in references [5] and [6] respectively. The selected component values will - 4 -
6 2 Project Details be finalized depending on their performance through simulation and availability for purchase. 2.5 User Interface and Control System An interactive control system will be implemented for the design of the overall system. The user is allowed two inputs via a 4x4 keypad; the ac-voltage magnitude and frequency. This information is sent to a reference waveform controller (RC) in the form of a modulation index and reference frequency. The reference controller calculates and passes a time-varying reference wave with the integer number of SMs to be inserted in the upper and lower arms to their respective valve controllers (VC). The VCs will perform a sort and balance routine that is used to determine the correct number of SMs to be inserted based on their respective voltage levels and direction of current. The VCs will then be responsible for sending the firing signals to the respective gate drivers. 2.6 Switches and Gate Driver Circuitry The gate driver circuit is the interface between the control system and the high power switches of the converter. MOSFETs have been chosen over IGBTs for the design due to their efficiency at lower power levels[7]. A gate driver circuit with a floating channel will be used to alleviate changing MOSFET source voltages and allow for bootstrap operation. Optocouplers will be used between the controller and the other gate driver circuitry to provide electrical isolation from the high voltage gate driver circuit. A dead-time generator will be used to delay the firing pulse of each SM switch to avoid short circuiting during finite switching time. 2.7 Sub-Module Capacitor Voltage and Arm Current Measurement System The voltage across the capacitor in each sub-module has to be measured continuously to determine the switching routine. The voltage will be measured with a voltage divider or DC/DC converter to produce a scaled voltage with a maximum output of 5V (logic level). The valve - 5 -
7 3 Specifications controller will serially acquire the measured voltage through an analog multiplexer. The current through each arm will be measured with a hall effect sensor with a digital output directly connected to the valve controller. 2.8 Future Provisions The system design will allow for additional features such as scaling up to a three-phase converter with a closed-loop speed control system. The controls will include functionality that allows for user input of speed; the main controller determines the appropriate magnitude and frequency of the output ac voltage that will achieve the desired motor speed to a certain accuracy (that is not specified at this time). 3 Specifications The designed converter is required to meet the specified distortion level under the nominal conditions listed in Table 1. The properties and ratings of the motor to be driven is listed in Table
