Intersective PWM
Description
Connections
Parameters
Modelica Standard Library
The Intersective PWM component transforms the input space phasor u to 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 the inverse of the positive fire signal.
The user can choose from four 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
