Performance Evaluation of a Single‐Phase Dual‐Load Simplified Split Source Inverter With High Voltage Gain

ABSTRACT This work proposes a single‐phase Simplified split source inverter with dual output. The topology consists of four power electronic switches, and one of the switches is added across one leg of the H‐bridge. A hybrid quasi‐sinusoidal pulse width modulation technique is implemented to ensure the inductor charges at a constant duty cycle that helps to enhance the input DC voltage and to charge the capacitor to perform the inverter action. The circuit design of the proposed topology has mitigated the effect of the common mode voltage (CMV) problem. In the previous literature, the family of single‐phase split source inverter (SSI) topologies has been analyzed with a single‐load connected at their load terminals; in contrast, a dual load is connected across the H‐bridge terminals, and its performance is analyzed in this work. Different test cases are considered to evaluate the performance of the steady and dynamic states of the topology. The mathematical analogy is evaluated using MATLAB/SIMULINK software with different loads. An experimental prototype is designed in the laboratory, and its control algorithm is provided using an Artix‐7 FPGA board.
