摘要：
Y-source inverter has been proposed for a few years, but it inherits many problems from coupled-inductor impedance-source inverters (CISIs). The most common drawback comes from the leakage inductances which leads to less efficiency and large dc-link voltage spikes. The dc-link voltage spikes then bring heavy burden on switches voltage level and result in a lower overall step-up ratio. Therefore, a modified Y-source inverter (M-YSI) has been proposed in this paper to solve the above problems by adding additional path for the leakage energy. The simulation based on PLECS has been carried out with in-depth analysis. Besides, experiment results have been presented to verify the simulation.
