A new PWM control scheme using a triangle waveform modulated by output voltage

In this paper, a new PWM control scheme using a triangle waveform modulated by output voltage is presented. Since the proposed control scheme only uses a comparator with hysteresis and a feedback resistor, numbers of components in a control circuit are reduced. In addition, because no error amplifier is used, the stability of the converter becomes excellent. The steady-state analysis of the proposed converter is performed and verified by the experiments.
