Abstract
In accordance with at least one aspect of this disclosure, an isolated drive (e.g., for a generator controller) includes a gate driver configured to operatively connect to a switch to drive the switch between a first state and a second state, a transformer configured to power the gate driver and provide an ON/OFF signal to the gate driver, an input line configured to connect a first side of the transformer to the gate driver, and a floating return line configured to connect a second side of the transformer directly to a source terminal of the switch such that parasitic currents from the transformer and/or drive circuit bypasses the gate driver and flows to the floating return line.
