摘要:
An active circuit for delivering three phase AC input power received from a three phase rectifier to a boost converter and a method of operating the same. In one embodiment, the active circuit includes a phase selection switching circuit, coupled to the rectifier, that selects an inner phase of the three phase AC input power. The active circuit also includes a switching network, coupled to the phase selection switching circuit and the rectifier, that controls a current waveshape of the inner phase and a current waveshape of at least one other phase, thereby to reduce harmonics associated with three phase AC input current.
