CURRENT SHARING CONTROL FOR PARALLELED POWER CONVERTERS

摘要

Current sharing between paralleled power converters (110,210) is attained by adjusting the error signal in the converters' regulation circuits to assure that all the paralleled converters have a regulated output voltage that forces the converters to share the load equally. In particular circuitry (140) is provided to limit the variation in output voltage that can be achieved through operation of the current sharing control.
