HIGH INTENSITY DISCHARGE LAMP WITH BOOST CIRCUIT

摘要

A circuit for operating a high intensity discharge (HID) lamp includes an H- bridge connected between a common terminal and a power line, and a control circuit connected to the H-bridge. A boost circuit is connected in parallel with the H- bridge between the power line and the common terminal, where the boost circuit includes a resistor, a Zener diode and a capacitor connected in series.
