Abstract
A constant-frequency, phase-shifted-mode, PWM (pulse-width-modulated) DC-DC power converter is described which incorporates two-stage inverters with high-frequency transformer links and saturable reactors as nonlinear elements. The proposed converter performs efficient zero-voltage switching over a large load range (no limitation for load range) and a wide voltage regulation range. Its steady-state characteristics are evaluated and discussed on the basis of computer simulation and experimental results. The experiments were carried out with a 0.5 kW 500 kHz breadboard, and power conversion efficiency of more than 88% was obtained.<>Keywords
