I am trying to design a PWM inverter in Orcad PSPICE where i am using a Vpulse source from library to generate MOSFET triggering pulses for H-bridge and it works fine for square waves.
But i if i want to generate sinusoidal pwm to drive the h-bridge how can i accomplish it in orcad pspice and drive the mosfets accordingly.
Desired PWM output in simulation
I figured out that sinusoidal pwm is generated by comparing a sinusoidal wave with triangular wave.Is there any way we could simulate sine pwm in orcad pspice and drive the h bridge accordingly different switching topologies.?
I would appreciate any help or suggestions that will help me to achieve my intended purpose of making prototype of sine wave pwm generation like as mentioned above in picture using orcad pspice.
Thank You for your time :)
