POWER SUPPLY WITH INTERFERENCE SUPPRESSION, AND METHOD FOR OPERATING A POWER SUPPLY |
摘要 |
A switched-mode power supply comprises a transformer with a primary winding and a secondary winding. A switch is coupled in series with the primary winding and configured to repeatedly interrupt a current through the primary winding. An inductor is located differently with reference to magnetic fields that the primary and secondary windings are configured to induce. A connection exists between the inductor and a circuit that contains one of the primary and secondary windings. The connection is configured to connect from the inductor to the circuit a first voltage that has a waveform representative of and a polarity opposite to a second voltage induced in the switched-mode power supply by leakage flux of the transformer at a switching moment of the switch. |
