PWM for Quasi Resonant Converter

The pulse width modulation (PWM) for the DC-DC power converter. This PWM consist of two input, the duty cycle,D, and the switching freqency, f. It is suitable for power converter that used frequency control for output modulation. One of the example is the quasi resonant converter.
The quasi resonant converter's output voltage is controlled using the switching frequency. Matlab Library only provide the PWM with duty cycle, D, as the input. This PWM have two input, switching frequency and duty cycle.
