Abstract
A gate drive topology and gate drive power supply topology designed to allow for a single Printed Wiring Board (PWB) design to be configured for two applications. In one application, select paired locations of solder pads or connector locations in the circuitry are populated with connecting 'spanning' resistors for integration within the gate driver and gate driver power supply topologies. The physical manifestation of these resistors on the PWB allows paralleled gate drive switching of corresponding power transistor devices for driving a load. A common gate-source voltage is applied to all three gates and the switching devices share dynamic switching and conduction loss. In an alternate application, the select paired locations are not populated with spanning resistors thereby rendering a circuit topology permitting independent operation independent power transistor gate driving switching operations. The path across the unpopulated spanning resistors provides a high voltage creepage isolation between independent gate driver circuits.
