| Abstract: | A 55W digital electronic ballast for Low Pressure Sodium(LPS) lamp with 110V DC supply based on Boost converter and half-bridge LCC inverter is presented in this paper.Its construction and operating process are analyzed.PWM control circuit of the Boost converter is composed with NE555 timers and operational amplifier.Microprocessor is used to realize the Pulse Frequence Modulation(PFM) control of the inverter.The software can ensure lamp's reliable igniting and constant operation,and realize lamp short-circuit and open-circuit protection.The flow chat of the software is given and the ballast is verified by simulation and experiment. |
