Circuit Oriented Model of Rectifiers for Large Signal Envelope Simulation

Envelope simulation has proven to be an efficient tool for the analysis and simulation of resonant converters such as frequency controlled ballasts, series-parallel and parallel resonant converters and converters with piezoelectric transformers. In this work a nonlinear model for the envelope simulation of the half-wave rectifier and full wave rectifier is presented. The model accounts for the input capacitance effect on the rectifiers and can be easily implemented in a circuit oriented simulator. It is valid for transient, DC and AC analysis, what is especially useful for the controller design
