Single Phase sine wave inverter (PSIM Simmulation)

>>Hi friends many of readers asked for sinusoidal modulation and sine wave inverter.

>>Here is the PSIM Simulation of single phase sine wave inverter.

>>Here a sine wave Source of 50Hz, 2V offset and 4V Peak to peak  is modulated by triangular wave of 4V.


Sine PWM inverter
>>You can see this in above image.


Now this signals are applied to full bridge inverter as shown in below figure.

Schematic of sinewave single phase inverter


Output of bridge if applied to inductive load it will generate almost sinusoidal waveforms current output is observed this can be seen in below waveform.

Sine modulated inverter

here is the PSIM simulation file.
