2-Level full bridge inverter (3-phase application)


The three-phase full-bridge inverter topology is the simplest and most widely used structure for systems connected to the grid. It consists of three sets of "bridges", each of which consists in two switches and their corresponding reverse-parallel diodes.
In order to generate a three-phase AC waveform, the three sets of bridges operate in phase shifted by 120 degrees and can be represented by six states. Since each state has its own voltage and current values, it is also called a six-pulse (6P) inverter.
