[0065] The working principle of the utility model is as follows: after the main power topology circuit is powered on, the rectifier and filter circuit performs rectification, the auxiliary power supply IC circuit performs voltage boosting, and at the same time, the PFC main control IC and the peripheral circuits stabilize the duty cycle of the MOS tube Q1, so that there is a stable DC voltage at both ends of the capacitor CE1. At this time, the Flybuck main control IC controls the duty cycle of the MOS tube Q2. At this time, the transformer T1 is coupled to the output end, and the rectification and filtering are performed through the rectifier diode D2, the rectifier diode D8, and the rectifier diode resistor. At the same time, the isolated feedback circuit detects the change of the output voltage, and then transmits it to the Flybuck main control IC through the optical coupler in the isolated feedback circuit. Finally, the Flaybuck IC FB pin controls the duty cycle of Q2 through the internal loop, so as to stabilize an output voltage.

[0066] When the thyristor is adjusted, its working principle is: after the mains is connected, it is rectified by the rectifier diodes D5 and D6, and then divided by the voltage divider circuit. Once the divided voltage is higher than the conduction voltage of the mos Q10, the mos Q10 is turned on, and a PW_IN signal is output to the GND pin of the microcontroller U2 through the signal isolation converter U3. After the microcontroller U2 receives the signal, it processes it through internal coding and outputs PW1 and PW2 to control the mos Q3 and mos of V1- and V2-. The switch of Q11; however, when the conduction voltage of the MOSFET Q10 in the thyristor signal detection control circuit changes, the signal of the signal isolation converter U3 will also change, and the changed signal will be fed back to the single-chip microcomputer U2 and reversely processed. By adjusting the dimmer to the totem drive circuit 1 and the totem drive circuit 2, the duty cycle of the MOSFET Q3 and the MOSFET Q11 is controlled, and the output circuit 1 and the output circuit 2 are adjusted, thereby controlling the brightness of the lamp or the speed of the motor of the external device, and realizing the control of the external sensor;

[0067] When the external regulating element is used for adjustment: after the mains is connected, the main power topology circuit generates a normal output voltage at both ends of the power capacitor CE6, the power capacitor CE2, and the power capacitor CE4, and provides power to the single-chip microcomputer U2 through the VDD output terminal. The single-chip microcomputer U2 detects the signals of each pin. When adjusting and controlling, any signal of the DIM+ connection terminal, the PW3 connection terminal, the AP connection terminal, the Pr+ connection terminal, and the PWIN input terminal of the thyristor is given to PW1 or PW2, and the signals PW1 and PW2 output by the single-chip microcomputer U2 change accordingly, and then the duty cycle of the mos tube Q3 and the mos tube Q11 is controlled through the totem drive circuit 1 and the totem drive circuit 2, and finally the output of the output terminal V1+ and the output terminal V2+ is controlled;

[0068] When remote control is performed, a control signal is sent to the cloud through an external terminal APP, and the cloud transmits the signal to the Bluetooth module, WiFi module and Zigbee module. The Bluetooth module, WiFi module and Zigbee module output the control signal from the PW3 connection end to the microcontroller U2 for encoding control, and output signals to control PW1, PW2, and then control the duty cycle of the MOS tube Q3 and the MOS tube Q11 through the totem drive circuit 1 and the totem drive circuit 2, and finally control the output of the output terminal V1+ and the output terminal V2+ to achieve remote control.

[0069] The utility model realizes a variety of control modes such as thyristor adjustment control, sensor control and remote control by setting control circuit one, control circuit two and control circuit three, and realizes voltage adjustment by setting a main power supply topology circuit. Combined with setting totem drive circuit one and totem drive circuit two, it can provide different drive power supplies for multiple external electrical appliances, which can be used for driving different external devices, thereby improving flexibility; the thyristor adjustment control function is realized by setting a thyristor signal detection control circuit and a signal isolation converter U3, thereby improving the efficiency of dimming and speed regulation; combined with setting a single-chip computer U2, the output power and state control of the output switch control circuit is realized; the control of the output switch control circuit by control components is realized by setting a control circuit two with a dimmer, a light-controlled sensor head and an adjustable resistor; and a variety of remote controls of the output switch control circuit are realized by setting a control circuit three with a Bluetooth module, a WiFi module and a Zigbee module, thereby greatly improving the applicability and flexibility of household power supply and reducing the cost of household control.
