specific Embodiment
[0052]Specific examples are as follows:
[0053] Take the flyback power supply as an example for the off-state power-taking circuit:
[0054] The first method: when the switch device is connected to the live line and the load line, when the light is turned on, the switch part is closed, the open state power-taking circuit works, and the obtained power is stored in the energy storage part to provide energy for the MCU chip.
[0055] When the light is turned off, the switch part is disconnected, and the off-state power-taking circuit works. At this time, the input of the off-state power-taking circuit is composed of live wire and load line, and the rectifier composed of diodes D1, D2, D3, D4, D5, and D6 The bridge circuit, the rectifier bridge circuit manages the alternating current into direct current, and the filter circuit filters the direct current. The flyback transformer, power management chip and switch tube are responsible for energy conversion. The feedback circuit sa...
Embodiment 2
[0061] In this embodiment, a switch device compatible with single live wire or neutral live wire is used as an example:
[0062] Such as Figure 4 As shown, when the user connects the switch device to the cassette, if the cassette only has live wires and load wires, connect the live wire and load wire to the switch device. At this time, the neutral line detection circuit does not work, and the MCU chip detects until the switchgear is in single live wire mode of operation.
[0063] Such as Figure 5 As shown, when the user connects the switch device to the cassette, if there are live wires, neutral wires and load wires in the cassette at the same time, the three wires can be connected to the corresponding terminals of the switch device at the same time. At this time, the neutral wire Through the diode D7, the Zener diode D8 is charged, so that the switch tube Q1 is turned on, and the drain of Q1 is pulled down to the ground. The MCU chip detects that the switch device is in a...
Embodiment 3
[0064] Embodiment 3 also provides a neutral line access detection circuit:
[0065] The zero line detection circuit is composed of diodes D7, D8, resistors R1, R2, R3, capacitor C1, and switch tube Q1. The diode D7 sorts the alternating current into direct current, and the resistors R1 and R2 are used to reduce system power consumption; the resistor R3 , Capacitor C1 and diode D8 form a voltage stabilizing circuit; the gate voltage of the switching tube Q1 is stable above the conduction threshold voltage of Q1, the drain of the switching tube Q1 is connected to the MCU chip, and the source is connected to the system ground signal, so When the switching device is connected to the neutral line, the gate voltage of the switching tube Q1 reaches its conduction threshold, then Q1 is turned on, the drain voltage is pulled to the ground, and the MCU chip detects the presence of the neutral line.
[0066] If the switch device does not detect the existence of the neutral line, the MCU ...
