High-Current Power Switching Elements for Bridge Conversion: In an exemplary embodiment of the present system and method, which is non-limiting, the A-PS 300 has a reconfigurable H-bridge converter (RH-BC) module 320 which includes four high-current power switching elements (HC-PS) 325.1, 325.2, 325.3, 325.4, also labelled in
The four exemplary SiC MOSFET power transistors 330 are switchable (from on-to-off states and vice-versa) at switching frequencies up to at least tens of kilohertz or hundreds of kHz. As such, the power transistors 330 are suitable for current/voltage switching/sampling at these frequencies; and so in combination are readily suitable for converting AC-to-DC voltages, converting DC-to-AC voltages, converting a first AC frequency to a second AC frequency, and voltage inversion, all via suitable controlled modulation of the gate elements of the power transistors 330. Details of this are known in the art of bridge converters, and will not be repeated here. (It will be noted that, with galvanic isolation, an output AC frequency may be the same frequency as the input frequency or may be a different frequency.)
