This paper presents a simple digital D1S lamp system with a power structure of flyback converter and full-bridge inverter using a low-cost 8-bit one-chip microprocessor to optimize the total system size and minimize implementation cost. The D1S lamp is a high intensity discharge lamp used for the headlight lamp of advanced cars. D1S lamp driver in the proposed system can generate high voltage to ignite the lamp. It can effectively control the power required to drive the lamp after the ignition. The proposed driver is consisted of an igniter, a DC-DC converter, a DC-AC inverter, and a control circuit. The DC-DC converter utilizes the flyback converter topology to minimize its component number. It is utilized to generate high ignition voltage of the D1S lamp. When the operation of the proposed system arrives in a steady state, the driver controls the lamp with AC current using the DC-AC inverter. In this paper, the operation principle of the proposed driver is described in details and the operation principle related to the igniter is explained briefly. Experimental results demonstrated that the proposed system had good performance for the D1S lamp.
