时钟控制供电电路及其工作原理

设计一种由指针工电子石英钟计时，用晶体管正反馈互补双稳态电路作为控制器，并采用电瓶供电与自动浮充电相结合的钟控供电电路，提高了电路的抗干扰能力，使其工作不受电网停电的影响。使用该电路去控制电网的接通、断开，具有安全、方便、经济、准确的优点，且可随意设定。时控器的个数相视用户的实际需要而定。

Clock Control Power Supply Circuit and Its Operating Principle

A practical clock control circuit of power supply is reported. In this circuit, a pointer type electronic quartz clock is used for timing ; the transistor Positive feedback complementary bistable circuit is usedas controllerl and the storage battery combining with automatic floating charge is used for promoting anti-interference ability of the circuit and thus ensuring its work unaffected by power cut of electric network. It issafe, convenient, economical and accurate to apply this circuit to control break and make of electric network.The circuit can also be designed at will. Its controllers can be varied in number according to user's practicalneed.
