In a DC-DC converter to control using pwm triangular waveform is the best option. Since then the increase in control voltage will be proportional to duty control is easy. The other control method is not related to pwm. Here both switching freq. and on-time of the switch are varied. This method utilizes force-commutated thyristors and the
