ISOLATED GATE DRIVER CIRCUIT FOR POWER SWITCHING DEVICES

摘要

The half- bridge (half-bridge) and full- bridge (full-bridge) for a power converter topology an upper (high-side) and the lower (low-side) embodiment of a removable gate driver circuit for driving the switching device is disclosed. Disclosed circuit is sufficient dead- service time (dead-time) , and operates over a wide range of duty cycles (duty cycle), a single power supply and (V _CC ) require . In a typical application for such a circuit the cold cathode fluorescent lamp is powered by high voltage DC rail , (cold cathode fluorescent lamp: CCFL) comprises an inverter .
