Abstract: A circuit includes first and second electronic switches, first and second excitation circuits, and first and second inductors. The first and second electronic switches are electrically coupled in series. The first and second excitation circuits are used for respectively controlling the first and second electronic switches to be turned on and turned off and are configured to synchronously switch the first and second electronic switches. The first inductor is electrically coupled between the first excitation circuit and the first electronic switch, for transmitting the switch control signal of the first excitation circuit to the first electronic switch. The second inductor is electrically coupled between the second excitation circuit and the second electronic switch, for transmitting the switch control signal of the second excitation circuit to the second electronic switch.

Abstract: An exemplary power conversion system includes a power conversion device and a control system. The power conversion device converts electrical power from one form to another. The power conversion device includes at least one switching element capable of being turned off to block an electrical current flowing through the at least one switching element. The control system is electrically coupled to the power conversion device for monitoring an electrical current flowing through the at least one switching element and for monitoring at least one parameter in association with the operation of the power conversion system. The control system further generates an over-current threshold value that is variable with respect to at least one monitored parameter.
