大功率磁保持继电器起动电路的设计

The design for starting circuit of powerful magnetic self-perpetuating relay

为了从硬件上增加起动电路的自我保护，减少继电器起动时对控制电路中智能芯片的干扰，对双极性大功率磁保持继电器起动电路的常见方案进行了改进。

In order to enhancing the self-protection of the starting circuit and reducing interference in intelligent chip of control circuit while relay starts, this paper improves the ordinary program of starting circuit of bipolar powerful magnetic self-perpetuating relay.
