Abstract :
A high-frequency-link AC-to-DC converter with sinusoidal input current and high-quality power factor is discussed. A bridge configuration is used for both boosting and inverting stages. Input line current is sensed and firing of the power transistors S1 to S 4 is inhibited using a pulse-width modulation (PWM) modulator. The proposed AC-to-DC converter, which includes control circuitry for instantaneous current control implementation, is capable of providing a wide-range-regulated output direct voltage. A performance evaluation of the proposed converter was carried out theoretically and experimentally, with highly satisfactory results
