Y-source inverter is a power electronic converter that can achieve an excessive voltage boost with a weak through dutyfactor. Due to the addition of three-winding coupling inductance, the inverter is more flexible in choosing turns ratio and has higher reliability. This study examines the history of Ysource inverter (YSI) development as well as the evolution of its topology, and identifies advantages with regard to Z-source inverters and conventional inverters. Then state analysis and mathematical analysis of I-YSI, a typical topology of Y-source inverter, are carried out to obtain the current situation of each part of the inverter, and the problem of DC chain voltage maximum caused by leakage induction is pointed out. To solve the voltage peak problem of DC chain, two solutions are summarized, including adding energy absorption loop and changing control strategy, and the two strategies are analysed in detail. Finally, the possible development direction of YSI is discussed. The development of the YSI will benefit greatly from the research implications of this study.
