A CIRCUIT TO REDUCE STRAY INDUCTANCE AND A 3-PHASE CONVERTER THEREOF

摘要

The present invention relates to a novel circuit, method and three-phase multi-layer Voltage Source Converter / Inverter (VSC/VSI) with multi-layer, sandwich bus-plates to converter to minimize the stray inductance of the interconnections and which will enable the converter to be operated at higher switching frequencies without any dissipating snubber. A capacitor resistor network is also proposed which has negligible losses to snub the voltage spikes generated due to minimum stray inductance, if any in the new three-phase multi-layer Voltage Source Converter / Inverter.
