Abstract

A small-signal model for zero-voltage-transition pulse width modulation (ZVT-PWM) boost converters is derived in this paper. The accuracy of the developed model is verified by experimental measurement. It shows that the ZVT-PWM boost converters exhibit better dynamical behavior than the conventional PWM boost converters. To achieve output voltage regulation and line voltage disturbance rejection of ZVT-PWM boost converters, a classical controller and a modified integral variable structure controller are designed. The output voltage regulation in the presence of line voltage and load variations for both controllers are compared by experimental results.
