Abstract :
This paper presents a high-frequency electronic ballast for high intensity discharge lamps. A new fixed frequency dimming method with low electromagnetic interference (EMI) features is developed in this research. The proposed electronic ballast has the advantages of high power density, simple circuit, and low EMI features. The circuit operating principle and design procedures are described in detail. A laboratory prototype was built and tested. The simulation and experimental waveforms verify the feasibility of the proposed scheme
