Seven levels triphasic inverter design controlled by a state machine

Abstract

This article describes the design of a seven levels triphasic inverter circuit, separated in three stages: monophasic signal generation stage, control stage and offset stage. For the monophasic signal generation stage was used an asymmetric cascade inverter based thyristors. For the control stage was used a finite state machine with JK flip-flops. For the offset stage, monoestable circuit was preferred over an RC circuit, because it causes significant power losses and negative effects on the output signal.
