[0034] When the embodiment of the present application is in use: four outputs per phase, a total of 12 outputs for three phases, each high and low voltage is controlled by optical coupling isolation, each phase has an independent zero-crossing detection circuit, and provides an accurate trigger reference signal for dimming. F1 is a fuse, which plays a protective role when the circuit is overcurrent. VR1 is a varistor, which plays a role in protecting the back-end circuit when the circuit voltage exceeds 270V. The T1 transformer converts 220V AC into 9V AC, and then rectifies it into a half-sine wave DC through four 1N4007 full-bridge rectifiers. The voltage is divided by R2 and R3 and supplied to the base of Q1. When the voltage exceeds 0.7V, the transistor is cut off and the collector outputs a high level of 3.3V. When the voltage is lower than 0.7V, the transistor is turned on and outputs a low level. The microcontroller generates a zero-crossing signal by detecting the rising edge of the output waveform. PWM-A1 to PWM-A4 are the microcontroller output control signals, which are connected to the optocouplers U1 to U4 respectively. The optocouplers control the control pins of the thyristors Q2, Q3, Q4, and Q5, thereby controlling the on and off of the thyristors to achieve the dimming effect. R5 and C3 form a peak absorption circuit to reduce the excessive pulses generated when the thyristors are turned on.
