| Abstract |
In this paper, it has been proposed the simultaneous control of PFC (power factor corrector) and electronic ballast for fluorescent lamp by one chip micro-controller. Boost DC-DC converter is adopted for PFC, and half bridge inverter for electronic ballast. It controls, simultaneously and independently, the boost DC-DC converter and the half bridge inverter. As PFC and electronic ballast are controlled by one chip micro-controller, it is possible to achieve the simpler and the cheaper controller for fluorescent lamp. Experimental results have shown the feasibility of the proposed simultaneous control of PFC and electronic ballast by one chip micro-controller. |
