| Abstract: | This paper introduces a newly developed intelligent portable battery charger with 4 kW high frequency soft switching circuit. The main circuit of the charger is a zero voltage and zero current switching full bridge PWM converter. A phase shift resonant controller UC3875 is used as a voltage and current regulator. A single chip microcomputer 89C51 is used as an intelligent controller to change operation model automatically. In the paper, the composition of the hardware and its operation principle are given, and the application of UC3875 in this charger is introduced in detail. The operation model and the software in single chip microcomputer 89C51 are also presented. Finally, the experimental waveform of the main circuit is given. The result proves that the charger is able to auto adjust control structure and parameters according to charging process, and can diagnose self fault and realize human free duty during charging process. |
