Abstract:
1. A power system, comprising: a plurality of power sources; a plurality of converters electrically connected to the power sources respectively in a one-to-one manner, wherein each of the converters comprises: a power stage circuit electrically connected to one of the power sources in a one-to-one manner to convert from an input voltage to an output voltage: a positive feed-forward control circuit electrically connected to one of the power sources in a one-to-one manner for providing a feed-forward control signal to positive feed-forward control each of the converters; a driver electrically connected between the power stage circuit and the positive feed-forward control circuit; and at least one load electrically connected to the converters, wherein the positive feed-forward control circuit has an adder connected to a positive terminal of the driver, and the drive outputs a driving signal to the power stage circuit according to the feed-forward control signal.
