L-D snubber for different type PFC circuit

In the UPS and communication power supply system, the output voltage of the PFC circuit is relative high. The phenomenon of reverse recovery is also relative serious for the use of a high-voltage diode. A simple L-D snubber circuit, suitable for PFC circuit of every kind of power system demanding hi...

More Information
Summary:In the UPS and communication power supply system, the output voltage of the PFC circuit is relative high. The phenomenon of reverse recovery is also relative serious for the use of a high-voltage diode. A simple L-D snubber circuit, suitable for PFC circuit of every kind of power system demanding high cost, can suppress the phenomenon of reverse recovery of the diode to reduce all kinds of loss of switches caused by the phenomenon and make better efficiency of power system.
