Metal-halogen lamp electronic ballast prototype design of digital control

On the basis of digital control plan analysis of metal-halogen electronic ballast,design was made to main circuit and control circuit of the circuit topology, and the selection and design was proposed to the model and the parameters of the main circuit and control circuit of PFC, DC/DC, DC/AC three-stage structure. And a set of digital control metal-halogen electronic ballast with high power factor and low-frequency square-wave output was manufactured.Via analysis of the experimental results,it is verified that the raised digital control plan is feasible.
