| Abstract |
A snubber configuration having minimum component count and minimum losses is presented for inverters. Component count reduction is achieved by sharing a single snubber capacitor between each pair of power switches in each leg and relocating leg inductances to the dc-link, where they are shared by all inverter legs. This is particulary interesting when using devices in power pack modules. In high load çurrent operation no net energy is transfered to the snubber, giving no losses snubber operation. At low load, excess energy is stored as current in the inductors. A way to return this energy to the supply is presented, thereby achieving minimum losses under all load conditions. |
