Webb20 mars 2024 · There are three forms of discrete sine wave PWM, which are:--Sawtooth carrier regular sample PMW--Triangle carrier symmetrical PWM--Triangle carrier asymmetrical PWM. The 'Sawtooth carrier regular sample PMW' induces a huge amount of 2nd harmonic component, so it is the worse PWM strategy for three-phase inverters. WebbYes, the PWM signal on the primary is one of them, but so is the output sine waveform on the secondary. One way to think of it is that the voltage waveform is the PWM signal … WebbAn effective PWM peripheral must be able to generate complex pulse width waveforms with minimal CPU overhead or intervention.
