In many applications, it is important for an inverter to be lightweight and of a relatively small size. This can be achieved by using a High-Frequency Inverter that involves an isolated DC-DC stage (Voltage Fed Push-Pull/Full Bridge) and the DC-AC section, which provides the AC output.
A part of main switches are connected to high frequency arm and the remaining switches to low frequency arm. All main switches of high frequency arm operate at Zero Voltage Switching (ZVS) turn on and all the main switches of low frequency arm operate at 50 Hz to reduce switching losses.
All main switches of high frequency arm operate at Zero Voltage Switching (ZVS) turn on and all the main switches of low frequency arm operate at 50 Hz to reduce switching losses. The main purpose of using Unipolar PWM inverter is to reduce output voltage harmonics.
Single phase Unipolar PWM inverter has been compared using different configuration. Configuration 1 is a soft-switching inverter consists of high frequency arm and low frequency arm. All the main switches of high frequency arm operate at ZVS turn on. Configuration 2 is an conventional hard switching PWM inverter.
