Circuit and Method for Potential-Isolated Energy Transfer with Two Output DC Voltages |
摘要 |
A circuit for potential-isolated power transfer from a primary side to a secondary side with two secondary-side output DC voltages, wherein the absolute value of the first output DC voltage is higher than the absolute value of the second output DC voltage. The circuit comprises a transformer, which has first and second windings with a common center tap on the primary side and a third winding on the secondary side. The ratio of the number of turns of the first and second windings is a function of the ratio of the two secondary-side output DC voltages. The center tap is connected to a DC voltage source, the first winding is connected to a first transistor and the second winding is connected to a second transistor. The transistors are connected to the primary-side reference potential. The output voltages are present at two diodes connected to the secondary-side third winding. |
