Single-phase full-bridge inverter wave control

What is a single phase full bridge inverter?

Single Phase Full Bridge Inverter is basically a voltage source inverter. Unlike Single Phase Half Bridge Inverter, this inverter does not require three wire DC input supply. Rather, two wire DC input power source suffices the requirement. The output frequency can be controlled by controlling the turn ON and turn OFF time of the thyristors.

How to control the output frequency of a single phase full bridge inverter?

The output frequency can be controlled by controlling the turn ON and turn OFF time of the thyristors. The power circuit of a single phase full bridge inverter comprises of four thyristors T1 to T4, four diodes D1 to D1 and a two wire DC input power source Vs.

What is a full bridge inverter?

Full bridge inverter is a topology of H-bridge inverter used for converting DC power into AC power. The components required for conversion are two times more than that used in single phase Half bridge inverters. The circuit of a full bridge inverter consists of 4 diodes and 4 controlled switches as shown below.

What are controlled switches for a full bridge inverter?

The controlled switches for Full-bridge inverters can be BJT, IJBT, MOSFET or thyristors. Controlled switches considered in this article are thyristors. The general concept of a full bridge inverter is to alternate the polarity of voltage across the load by operating two switches at a time.
