초록

This paper presents a model for p voltage controlled pulse width modulator (VCPWM), which can be used in any phase controlled converter having either manual or microprocessor based control. The circuit uses only one 555 timer, an OpAmp, some resistors, and capacitors. Although a large varieties of such circuits are available in the literature, this model is very simple with low cost and high performance.
