The invention discloses a charger starting circuit and a charger, and relates to the power supply field, a step-down conversion module is used for carrying out step-down on an AC power supply, a first rectification module is used for converting the step-down AC power supply into a DC power supply, and when the first rectification module outputs the DC power supply, a first control module controls a first controllable switch to be closed; the direct current activates the charger control unit. Therefore, when the alternating current power supply is the power supply for the garage, the converted direct current can supply power to the charger control unit, and when the storage battery is lack of power, the alternating current power supply can be the power supply in the garage, and the direct current electric energy converted from the alternating current can activate the charger control unit and the charger to charge the storage battery lack of power. And the storage battery does not need to be charged by using a mobile charger or another train, so that the cost of charging equipment is reduced, and the process steps are relatively simple.

    本发明公开了一种充电机的启动电路及充电机,涉及供电领域,由降压变换模块对交流电源进行降压,再由第一整流模块将降压后的交流电源转换为直流电,当第一整流模块输出直流电时,第一控制模块则控制第一可控开关闭合,直流电激活充电机控制单元。如此一来,当交流电源为库用电源时,转换后的直流电则能为充电机控制单元供电,在蓄电池亏电时,交流电源可以为库内电源,由交流电转换成的直流电能激活充电机控制单元,充电机为亏电的蓄电池充电,则不需要使用移动的充电机为或者使用另一列车为蓄电池充电,降低了充电设备的成本,流程步骤也较为简单。
