Abstract
In this paper we present large-signal and small-signal averaged switch models for the interleaved zero-current-transition (ZCT) buck converter, which has been proposed as an effective solution for high-voltage, high-power applications. It is shown that for the converter operating in continuous conduction mode the ZCT switch waveforms result in significant lossless damping in the converter frequency responses in comparison to the frequency responses of the standard PWM buck converter. The model predictions are verified by measurements on an experimental 500 V, 10 kW prototype
