Abstract
An apparatus comprises an energy transfer device that operates one or more input switches of an input side of an electrical isolation device to transfer energy through the isolation device to an output side of the electrical isolation device for activating a switch. The apparatus comprises a voltage conversion device that converts the energy from an input voltage of the input side to an output voltage to control the switch when the energy transfer is active. The apparatus comprises a passive turn off device that passively deactivates the switch when the energy transfer is inactive. The passive turn off device is disabled from deactivating the switch when the energy transfer is active.
