Abstract	An efficient simulation approach is presented in order to analyze digitally-controlled switching mode power converter circuits and systems with feedback and feedforward control loops. The general computer-aided simulation procedure is based on a circuit and system equation modeled by time-varying resistors which substitute active power switches and the passive diodes of the converter circuits in addition to a state equation for the inductors and the capacitors, an algebraic computation method to transform the matrices of the circuit equation into the matrices of the state equation. In this approach, the numerical integration is achieved with rather less numerical calculation steps because of the small matrice size of the state equation. The effectiveness of this approach are proved by introducing a newly-developed PWM DC-DC high-power converter operating at high-voltage transformer parasitic circuit parameters under a digital control scheme.
