摘要：

To solve the high DC-link voltage and shoot-through current in traditional coupled-inductor impedance-source inverters, a shoot-through current suppressed Y-source inverter with low voltage spike was proposed. The shoot-through and non-shoot-through operational modes were analyzed in detail and key waveforms were provided. By applying current-second and voltage-second integrated over a switching period, the voltage and current stresses of the key devices was derived. Compared with improved Y-source inverter, the proposed topology applies lower shoot-through ratio when considering same voltage gain and winding factor, which increases the modulation ratio range and improves the efficiency of DC-link voltage, and reduces DC-link voltage spikes. Moreover, it can suppress the increment of shoot-through current. When the DC-link voltage is the same, the proposed topology requires a smaller shoot-through time, resulting in a less conduction losses in shoot-through state. Finally, a 240 W prototype was built and experimental results verify the superiority of the proposed Y-source inverter. © 2024 Editorial Department of Electric Machines and Control.
