A multiphase power converter includes a plurality of subconverters and a control circuit. Each subconverter has an input circuit, an output circuit, and a magnetic core coupling the input circuit to the output circuit. The magnetic core of at least one of the plurality of subconverters has a core section that is shared by the magnetic core of another one of the plurality of subconverters. The control circuit is configured to operate the input circuits of the plurality of subconverters with different phases. The magnetic cores may be cores of a transformer, a coupled inductor, etc.

Multiphase power converters having shared magnetic core sections

An electronic circuit breaker has an input, an output, and a switch electrically connected between the input and the output. The electronic circuit breaker monitors the energy dissipated by the switch and opens the switch when the energy reaches a threshold value in order to protect the switch. The electronic circuit breaker also monitors the current through the switch and opens the switch when necessary to protect the load.
