DAMPING CIRCUIT FOR DC-TO-DC CONVERTER Russian patent published in 2009 - IPC H02M3/335 

FIELD: electricity.

SUBSTANCE: invention relates to conversion technology and can be used in high-frequency converters for secondary power sources. The damping circuit for a dc-to-dc converter comprises series connected primary transformer winding and a power switch, connected to input terminals of the converter, where the control input of the power switch is connected to the control output of a control unit. First and second diodes are anti-parallel-series connected to the secondary winding of the transformer. The point of connection of the first and second diodes is connected to the first terminal of an inductance choke, the second terminal of which connected to the first output terminal of the converter and to the first terminal of the first capacitor, the second terminal of which is connected to the second output terminal and to the point of connection of the secondary winding of the transformer and the second diode. The converter also comprises a third diode and a second capacitor. There is also another secondary transformer winding, first and second resistors and a switch.

EFFECT: wider range of application and increased reliability.
