Control process for a matrix inverter uses a serial superposition of all input phases and employs neighboring switches in commutation

摘要

A control process for a matrix inverter comprises three input (RST) and three output (ABC) phases and a bi-directional anti-serial semiconductor switch with an antiparallel open circuit diode to connect input and output phases. The output voltage comprises a serial superposition of all input phases with commutation only between neighboring switches.
