摘要
Methods and systems for balancing output currents of parallel connected resonant converters are disclosed. One such method includes matching switching frequencies for a pair of resonant converters. The method also includes carrying AC output currents of resonant tanks of each of the resonant converters through a current controlled voltage source that is coupled to each of the resonant converters of the pair of resonant converters at an AC side of each of the resonant converters of the pair of resonant converters. The method further includes inducing, for the pair of resonant converters, a voltage that is proportional to a difference in the AC currents carried through the current controlled voltage source by passing the AC currents through the current controlled voltage source. The induced voltage is oriented to oppose the greater of the AC currents and to increase the smaller of the AC currents.
