FULL-BRIDGE AND HALF-BRIDGE COMPATIBLE DRIVER TIMING SCHEDULE FOR DIRECT DRIVE BACKLIGHT SYSTEM

摘要

A driver circuit or controller flexibly drives either a half-bridge or a full-bridge switching network in a backlight inverter without modification, redundant circuitry or additional components. The driver circuit includes four outputs to provide four respective driving signals that establish a periodic timing sequence using a zero-voltage switching technique for semiconductor switches in the switching network.
