Title:
【発明の名称】エネルギ回収を備えたソリッドステート・モータ・スタータ
Document Type and Number:
Japanese Patent JP2002508648
Kind Code:
A
Abstract:
A motor starter circuit providing recovery of the energy trapped in the motor windings when the supply voltage and current have opposite polarities by selectively controlling actuation of a plurality of high speed switches. The circuit, for use with a multiphase motor and power source that provides positive and negative voltage alternations which result in the generation of a load current in the motor having positive and negative alternations, includes a plurality of switch-diode combinations electrically configured such that for a given pair of supply voltage/load current polarities, only one diode of each combination may be forward biased.
