How pure sine wave inverter works / How to program SPWM microcontroller / Pulse width modulation PWM

9 місяців тому

#SPWM (#sinusoidal_pulse_width_modulation) microcontrollers are used in #pure_sine_wave_inverters to generate more accurate AC sine wave.
This #microcontroller can store the required commands, to generate the necessary waveform for the #inverter, through proper design of switching pulses.
The basis is to use an #H_bridge with #IGBT_switches, to reverse the load current, by inverting the DC voltage across the load terminals, alternately.
All these things are explained well in this video, with fine animation work.

Thank you.

I was hoping you would explain dead time to prevent short circuit on the H-bridge. Also some form of voltage feedback for voltage sag or input voltage fluctuation compensation.

Good video. Do you have anything that talks about the 100% low-side method and 50% offset method for Sin Inverters?

Sir, very nicely , easy to understand the programming of a PWM microcontroller and how to generate sine wave voltage output using IGBT transistors from DC input. Sir, could you forward a circuit diagram to generate 3 phase voltage output with DC input. With Sincere Appreciations Vijay Mohan
