1. , the mine lamp charging auxiliary equipment, it is characterized in that:

  • it just comprises, negative input and just, cathode output end, be connected with voltage-adjusting unit between electrode input end and the cathode output end, be connected with the voltage sampling unit between negative input and the cathode output end, be connected with a reference source between electrode input end and the negative input, be connected with the current adjustment unit and the current sampling unit that are in series between negative input and the cathode output end, other be provided with voltage ratio than amplifying unit and current ratio than amplifying unit, the both has two inputs and an output;

    described voltage ratio is connected voltage sampling unit and a reference source respectively than two inputs of amplifying unit, and its output then connects voltage-adjusting unit;

    Described current ratio connects current sampling unit and a reference source respectively than two inputs of amplifying unit, and its output then connects current adjustment unit.
