Title: Circuit for zero current switching forward power conversion and method
Inventor: PATORITSUIO BUINSHIYARERI
IPC: H02M1/08
Filed: 1990-11-22
Abstract: PURPOSE: To obtain a highly efficient converter by providing a switching element at the secondary side of a power transformer, opening or closing the switching element, and governing a transferred energy selectively. CONSTITUTION: A first switch 26 and a second switch 28 repeat ON/OFF by a control circuit 22 and a controller 32, respectively. The second switch 28 is connected to both terminals of a capacitor 20. An inductor 24 is connected in series between the capacitor 20 and a load. When the second switch 28 is ON, a first switch 26 is turned on by the control circuit 22 if a current that is equal to a positive current IOUT flows to the second switch 28 and the operation cycle of the converter is initiated. Then, a second switch is turned off and an energy transfer phase results. When a current I1 reaches 0, the first switch 26 is turned off. Further, when the voltage of the capacitor 20 reaches 0, the second switch 28 is turned on.
