Abstract

New electronic ballast for metal halide laws is proposed New ballast has higher efficiency than that of conventional ballast. Proposed 2 stage ballast uses low arm switch as synchronous rectifier mitch. Switch-on voltage drop is smaller than that of diode in small current(<1.5A). High arm switch is turned on in zero voltage in proposed ballast. So conduction loss and switching loss are reduced Index word - synchronous rectifier mitch, toro voltage switching, conduction loss, switching loss.
