Aiming at the many shortcomings of analog control electronic ballast, this paper proposes a control method of digital control electronic ballast using PIC16F873 series single chip microcomputer, which can realize the control of the start-up and steady-state operation of metal halide lamp and realize the load matching with different stages of lamp. The working principle and circuit structure are introduced, and the method is verified to be feasible through experiments.
