Abstract
A vehicle may include an electric drive system including switches having gates configured to control the switches. The vehicle may include a galvanic isolation coupling having a primary side electrically connected with an input power source and a secondary side electrically connected with a gate driver circuit. The gat driver circuit has a controller configured to actuate the gates and a power supply circuit electrically connected to the controller to provide backup power. The galvanic isolation coupling may be a flyback converter.
