single phase full bridge inverter with R load circuit working and waveforms in power electronics
Introduction
In this article, I’m going to tell you about a Single phase full-bridge inverter.
The word inverter means Dc to Ac. The input is Dc and the output is Ac. For designing
Full Bridge Inverter there is 4 MOSFET is required two for the positive half
cycle and two for the negative half cycle. I am using PSIM’s latest version for
designing.
My circuit is not hardware-based my design circuit is for
power electronics practical. Power electronics is a subject that teaches in
Engineering Universities. In Power Electronics we study the conversion,
inversion, stepdown, step up, Cyclo-converter, Buck Converter, Boost Converter,
Buck-Boost Converter.
Circuit Diagram
Working
The working operation of this circuit is that two MOSFET is
for a positive half cycle and two MOSFET is for the negative half cycle. The
simplest load is Resistor. The value of the resistor depends upon your
requirement in my circuit I use the value of the resistor is 1k and the triggering
angle for mosfet1 is 0 180, mosfet2 180 360, mosfet3 180 360, mosfet4 0 180.
The load is put in between the MOSFETs.

MOSFET
The MOSFET is a metal oxide field-effect transistor. This is
a three-terminal device that is used for switching. One pin is Drain second pin
is the gate and the third pin is the source.
