About Three-phase half-bridge square wave inverter

Half H-bridge is one of the inverter topologies which convert DC into AC. The typical Half-bridge circuit consists of two control switches, 3 wire DC supply, two feedback diodes, and two capacitors connecting the load with the source. Control switch can be any electronic switch i.e. MOSFET.

The operation of half-bridge with pure resistive load is the simplest. A purely resistive load does not have any storage component, so the circuit doesn’t need feedback diodes.

The first two waveforms show the pulses applied to the switches where each switch receives the pulse when the complementary switch is off. 3rd graph shows the voltage waveform across the load. This shows that.

As pure inductive load doesn’t exist, it must have some wire resistances and material resistance. Hence, more practical RL load is shown in the waveform rather than showing a theoretical. The instantaneous load.

The working operation of half-bridge for both L and R-L load is the same. As neither 100% pure inductive load nor pure resistive load exists in real life. A pure inductor has some value of ohmic resistance, so R-L.
