In the positive half cycle (N-L) of the alternating current, the level of a U51 pin of the operational amplifier is greater than 0V, and the U54 pin outputs high level; in the negative half cycle (L-N) of the alternating current, the level of the U51 pin of the operational amplifier is less than 0V, and because the U5 supplies power to the single power supply, the U54 pin outputs low level, so that a 50% duty cycle square wave with the frequency equal to the frequency of the alternating current is obtained as shown in a graph c.

As shown in fig. 4, the MOS FET solid-state relay U2 is used to drive the triacs Q111, R10, and R11 to limit the on-current of U2, thereby protecting U2 and Q1. The MOS FET solid state relay is a fully controllable device (silicon controlled rectifier is a semi-controllable device), and has the advantages of high gain, low internal resistance, small conduction voltage drop, high response speed, small volume and strong anti-interference capability. When Q2 is turned on, current flows through the U2 led to turn on the U2 MOS FET, and when Q2 is turned off, the U2 MOS FET is then turned off. After the U2 triggers the g pole of the bidirectional thyristor Q111 to switch on the Q1, the U2 is switched off at a moment before the next zero point is continuously switched on, in the whole process of switching on the Q1, the g pole of the Q1 has trigger voltage, the bidirectional thyristor is switched on by using the MT1MT2 two poles under the triggering of the g pole, the g pole trigger voltage is removed, the thyristor cannot be switched off as long as the voltage at the two ends of the MT1MT2 is not zero (the voltage between the MT1MT2 is greater than the minimum switching voltage, and the current flowing through the thyristor is greater than the minimum maintaining current), and the thyristor cannot be switched off until the next zero point arrives, and the thyristor is in a semi-controllable state at the moment. Therefore, the trigger circuit of the silicon controlled rectifier needs to have extremely high anti-interference capability, and the anti-interference capability of the trigger circuit can be greatly improved by using the MOSFET solid state relay.
As shown in fig. 2, the fuel gauge circuit collects the high and low values of the input voltage and the output power value, and transmits the values to the control module, so as to realize the input overvoltage or undervoltage protection function, the output overcurrent protection function, or the output overpower protection function.
Further, the working process of the intelligent dimming switch may be as follows: when the dimmer starts working after the power supply is switched on, the internal MCU and the communication module start initialization, then the current input voltage, current and power are detected by the fuel gauge, any value of the current input voltage, the current and the power exceeds a standard range, the dimmer sends out an alarm (an indicator lamp of the dimmer flickers or a buzzer sounds) and prohibits output until the fault is relieved and the input power supply is switched off and then is electrified again. If the electricity meter detects the input voltage, the current and the power do not exceed the standard, the system continues to work and judges whether a user has a preset ambient light or a human body motion state value in the environment, if the preset ambient light or the human body motion state value does not exist, the dimmer waits for the lighting-on or dimming action of the user, if the lighting-on or dimming action exists and the user turns on the light according to the brightness value set by the user, the electricity meter continues to detect the voltage, the current and the power value after the lighting-on and makes corresponding actions. If the user has a preset ambient light or a human motion state value in the environment, the ambient light sensor and the ambient motion sensor continuously detect the human motion state in the environment, and if the ambient light or the ambient motion state accords with the preset value, the light is turned on according to a brightness value set by the user; after the lamp is turned on, the ambient light sensor and the pyroelectric sensor can continuously detect the ambient state until the ambient light or the ambient motion state does not accord with the preset value, and then the output is closed.
