Self reconfigurable, adaptable power electronics building block (A-PEBB)
摘要
說明書
In an exemplary embodiment, an SCPS may consist of four SiC MOSFET switches/devices, each with an antiparallel diodes, along with a plurality of electrical contactors (mechanical switches, relays) and/or electronic switches (low power transistors) which can be used to change the path flow of electric current in the SCPS, thereby adapting the operations of the SCPS in real-time. In addition, a number of inductors in the SCPS may be employed to further regulate the internal current flow. In one exemplary embodiments, two separate inductors (that is, inductors not part of a transformer unit) may be employed. Below, this document presents one exemplary connection topology for these elements.
Via the lower-power transistors, the adaptable SCPS can be self-configured to variously serve, at any one given time, as any one of a bidirectional DC to DC converter, a bidirectional DC to AC, and a bidirectional AC to AC converter; that is to say, the SCPS has multiple adaptable power conversion modes, all with embedded compact high frequency isolation transformer.
Among other modes, the SCPS can be self-configured as any one of a bidirectional buck, boost, or buck & boost DC to DC converter. By suitably changing the operational modes of the outer H-bridges, the operational modes of an entire A-PEBB can be changed or reconfigured for different power applications and different mission modes.
