| Abstract: | The operating principle of the reversly activated switching supply with single MOSFET is analyzed. The calculating methods for the primary and secondary currents, the voltage and the turns ratio of the high frequency switching transformer as weel as the duty ratio of the switch are presented. Some basic design rules for the transformer are given. The design of a reversely activated simple switching supply with a current type double closed loops PWM controller is given. Experimental results show that the performance is good. |
