This article outlines the definition and working principle of three phase bridge inverter. 180 degree conduction mode of operation, formula for phase & line voltages of three phase inverter is also explained in this article. A three phase bridge inverter is a device which converts DC power input into three phase AC output.
Three phase inverters provide more stable and balanced output voltage and current which leads to better power quality. Three phase inverters can help in minimizing harmonic distortion in electrical systems which reduces power quality. Three phase inverters are less affected by overvoltage events .
A DC -to -AC converter which uses a DC power source to generate 3-phase AC power is known as a 3-phase inverter. This type of inverter operates by using a power semiconductor switching topology.

A basic three phase inverter is a six step bridge inverter. It uses a minimum of 6 thyristors. In inverter terminology, a step is defined as a change in the firing from one thyristor to the next thyristor in a proper sequence. For getting one cycle of 360°, each step is of 60° interval.
180° Conduction Mode of Three Phase Inverter: In 180° conduction mode of three phase inverter, each thyristor conducts for 180°. Thyristor pair in each arm i.e. (T1, T4), (T3, T6) and (T5, T2) are turned on with a time interval of 180°. It means that T1 remains on for 180° and T4 conducts for the next 180° of a cycle.
