A 37-Level Switched-Capacitor Boost Inverter With Reduced Blocking Voltage on Semiconductors

This article suggests a 37-level switched-capacitor boost inverter employing 2 DC-sources, 3 capacitors and 15 switches to provide boosting factor of 3.6, where the S

is bidirectional, and all others are unidirectional. The bipolar output-voltage waveform is attained without an H-bridge. So, none of switches/diodes tolerate the Maximum Output-Voltage (MOV). The reduced devices per levels, capability of feeding low or medium power-factor loads and self-balancing of capacitors are other key features of suggested converter. It can also provide low Total Blocking Voltage (TBV) on semiconductors. The theoretical, comparative and simulation analysis approve the proper performance of suggested converter.
