Information

The intersective PWM transforms the input space phasor u to the three phase voltages, and compares them with the reference signals. As long as the phase voltage is greater than the corresponding reference signal, the corresponding fire signal is true. The switching pattern of the negative fire signal is just the inverse of the positive fire signal.

The user can choose from 4 different reference signals:

• Sawtooth1: sawtooth signal, same phase in all 3 phases
• Sawtooth3: sawtooth signal, phase shift between the 3 phases = period/3
• Triangle1: triangle signal, same phase in all 3 phases
• Triangle3: triangle signal, phase shift between the 3 phases = period/3
