On the system’s main circuit programme, the control circuit and a system fault detection. The Chargers used the main circuit full-wave rectifier circuit, Charging voltage and charging current can be predetermined and continuously monitored by the sensing means, so as to control the phase-triggered of the thyristor and maintain charging voltage and charging current at levels which is not greaten than predetermined limits, therefore the charging rate is continuously optimized. Experimental results of the prototype show that the proposed charger has the advantages of electric separation, simple frame, high efficiency, small volume, light weight and easy for the field application.
