Background Monolithic wide band gap power semiconductors capable of four quadrant operation (blocking bidirectional voltage and carrying bidirectional current) are emerging and becoming commercially available. Four-quadrant devices have historically been referred to as “Bidirectional Switches” (BDSs), and they have been implemented using...

Power converters convert electrical energy (e.g., convert alternating current (AC) into direct current (DC) and vice versa, change the voltage or frequency of current, or do some combination thereof). Transformers are key components in power converters and transfer electrical energy from one electrical circuit to another circuit or multiple circuits....
