Abstract
The utility model discloses an electronic switch open-state power supply circuit, comprising a main control return circuit and a triggering return circuit. The main control return circuit comprises a load and a main silicon controlled rectifier that are connected between the live conductor and the zero line of a power supply. The utility model is characterized in that the triggering return circuit comprises a main silicon controlled rectifier flip-flop, a charging circuit and a flip-flop circuit. When the electronic switch composed of the utility model is on the two states of closing and opening, two current supply return circuit are mutually isolated because of the reverse-biased close of a rectifying diode. Thus, the phenomenon appearing in the background art can not appear. Namely, because a current-limit resistor isn't effectively isolated with an igniter of the silicon controlled in the main control return circuit on the close-state, the silicon controlled is likely to be triggered by mistake and is conducting when the electronic switch is on the close-state. Simultaneously, the utility model adopts a bidirectional thyristor output photoelectric coupler to achieve the goal, so the circuit is extremely simple.
