JZ-22010C high-frequency switch power-supply module is produced with the advanced techniques of full-bridge phase-shifting PWM soft switch control. Its efficiency is enhanced and its harmonic is minished. The module inputs current with the equilibrium AC ternary-phase 3-line 380VAC so that there is no wastage in middle line. It input current through peak-restricting circuitry and EMI absorber circuit, and full bridge rectifier-filter circuit which change the ternary-phase AC voltage into pulsed DC voltage, then trough high-frequency full-bridge phase-shifting PWM which change the pulsed DC voltage into high-frequency quadrate-wave voltage. At last, through output rectifier-filter circuit, the stabilized voltage and current is outputted. Even when the electric network’ voltage and load change, the voltage and current can keep stable because the feedback-modulating circuit control phase-shifting PWM circuit.
