Title:
【発明の名称】非相称の故障を相称化する方法
Document Type and Number:
Japanese Patent JP2002502219
Kind Code:
A
Abstract:
The short-circuit protection operates on one half of the inverter to bring all the inverter phases to either the positive or negative supply potential. The power switches in the inverter (1R,2R,1S,2S,1T,2T) are controlled so that one half of the bridge is closed and the other half is open, stopping the supply to the motor and avoiding a short-circuit across the DC rails of the bridge.
