  • Lossless snubber circuit for use in power converters
    Patent number: 5636114
    Abstract: A switching power converter employing a novel lossless zero-voltage-switching passive snubber network having a power range of up to 5 KW is presented. The passive snubber network improves efficiency, power density, and transient performance, reduces switching losses and EMI, and permits fixed frequency operation of the switching power converter. The passive snubber network also reduces and/or eliminates large peak currents and reverse recovery current spikes normally seen in conventional switching power converters. The proposed passive snubber network may be used in various switching power converter topologies such as boost, buck, balanced, and flyback power converters.
