Abstract:
A power control circuit includes a solid state power controller operable to connect an AC power source to a load. The solid state power controller includes a first switching device and a second switching device arranged serially. Each of the switching devices includes a diode, a controller controllably coupled to each of the first switching device and the second switching device, such that the controller is capable of controlling an on/off state of the first switching device and the second switching device. The controller further includes a non-transitory memory storing instructions for causing the controller to perform the steps of: switching off a first switching device having a diode aligned with a current polarity of an AC current flow prior to a first zero crossing, delaying a switching off of a second switching device until after the first zero crossing, and switching the second switching device off after the delay and before a second zero crossing.
