N2 - A novel low voltage, high current AC/DC converter will be introduced. According to the required specification, the power converter which input is utility power supplies a low voltage DC output to load. The control strategy is fulfilled by a digital signal processor TMS32F28035 which is manufactured by Texas Instrument. By applying the phase shift control method, this novel low voltage, high current AC/DC converter has been realized. The new three legs phase shift DC / DC low voltage high current power supply [1∼4], can divided to five parts: diode full bridge rectifier, three legs phase shift control circuits, transformers, double inductor circuit and feedback circuit. Circuit operates as a single-phase 110 Vrms AC mains power input three legs phase shift control mode from the diode bridge rectifier circuit, the output voltage through the transformer and the phase shift control method converts to low voltage DC 12V output and supplies to pure resistor loading, feedback circuit are using a feedback resistor across the filter capacitor voltage to product a feedback signal. Digital signal processing (DSP) control board by a feedback voltage determines the three legs phase shift displacement in order to control the output voltage keep a constant value 12V. For this circuit have a zero voltage switching characteristics of the three legs phase shift mode power supply, the input voltage for single phase 110Vac and output load power is 12V/20A.
