Average and small signal modeling of zero-voltage transition three-phase
boost rectifier is performed. The effect of ZVT is introduced in the
existing model for the three-phase boost rectifier using the time-averaging
equivalent circuit approach. The small signal model is derived from the
average model. The small signal characteristics are compared to the
corresponding characteristics without ZVT. A model is also developed
for the independent analog current controller. The models are
experimentally verified. In order to perform in-depth study of control
approaches, a switching model is also developed. The models are used to
investigate various control approaches.
