A novel integrated rectifier and boost converter circuit architecture is disclosed. The rectifier architecture includes a plurality of identical half-bridge rectifiers connected to receiving antennas to convert wireless AC power into DC power. The integrated rectifier may be coupled in series with a charging inductor in a boost converter.

The present application provides a conversion system and a control method, including N power converters and N controllers, and N controllers one-to-one corresponds to the N power converters. In addition to receiving a first side current and a second side voltage of a corresponding power converter, each of the N controllers can also receive a neighboring direct current voltage signal which only reflects second side voltages of other M power converters in the conversion system, and perform voltage control on the corresponding power converter according to the received signal. The present application adopts fully distributed control, and does not need to set up a centralized controller. When parts of controllers fail, the other controllers can continue to work, so the reliability is higher.

The device includes a rectifier circuit for rectifying the three phase power input into a plurality of rectified outputs, a converter circuit for converting each of the rectified outputs, and a control circuit for generating the control signal based at least in part on the single direct current output. Each of the rectified outputs may have a common first mean voltage level, which is converted to a second mean voltage level based on a control signal. Each of the rectified outputs at the second mean voltage level are capable of being combined into a single direct current output.

The present improvement essentially integrates a DC link inductance within an interphase power transformer (IPT). The integration is achieved by creating auxiliary magnetic paths for leakage inductance inside the IPT core. The magnetic path can be created, for example, by incorporating extra portions of magnetic material commonly referred to hereinafter as shunts. The IPT flux shared between windings does not cross these shunts. Therefore, this magnetic path increases the self-inductance of the IPT but does not contribute to the mutual inductance between windings. This extra magnetic path allows for leakage inductance of a much higher quantity than that achievable with a conventional IPT.
