SignalPWM
Generates a pulse width modulated (PWM) boolean fire signal
Library
Modelica/Electrical/PowerConverters/DCDC/Control
Description
This controller can be used both for DC/DC and AC/DC converters.The signal input of the PWM controller is the duty cycle; the duty cycle is the ratio of the on timeto the switching period. The output firing signal is strictly determined by the actual duty cycle, indicated as d in Fig. 1.
 |
The firing signal is generated by comparing the sampled duty cycle input with a periodic saw tooth signal [Williams2006].
