Abstract: An isolated DC-to-DC switching power supply includes an isolation transformer having a magnetic core, a first winding around the magnetic core, a first winding-shield around the magnetic core, a second winding-shield within the first winding-shield, and a second winding within the second winding-shield. There is no direct coupling between the first winding and the second winding since the second winding is enclosed within the second winding-shield and the second winding-shield is enclosed within the first winding-shield.

Abstract: A high voltage protection module can include a housing having two chambers and a wall separating the chambers. The wall can have a hole through which a conductive element can pass to electrically couple an input with an output. The conductive element can be configured to break or fuse with the hole responsive to a high voltage event at the input.
