| Abstract |
This paper relates to a high-frequency (HF) link AC to DC converter with sinusoidal input current and high-quality power factor. A bridge configuration is used for both boosting and inverting stages. Input line current is sensed and firing of the power transistors S1 to S4 is inhibited using pulse-width modulation (PWM) modulator. The proposed AC to DC converter comprising control circuitry for instantaneous current control implementation is capable of providing a wide range regulated output direct voltage. The proposed converter is intended for a HF link Uninterruptible-Power-Supply (UPS) equipment. Performance evaluation is carried-out through theoretical and experimental means . |
