Embodiment Construction

[0006] Such as figure 1 As shown, C1, C2, L1, L2, and L3 form an AC filter circuit to filter out various interference waves of the AC 220V input power supply, and send high-quality AC power to the next-stage circuit. Among them, C1 and C2 are safety capacitors, L1 and L2 are differential mode inductors, and L3 is common mode inductors.

[0007] Such as figure 1 As shown, D1, D2, D3, D4 and T1 form an AC pulse width regulation circuit. Its input is sinusoidal alternating current, and its output is also sinusoidal alternating current. Only the output value can be adjusted according to the needs, and the adjustment is controlled by the duty ratio generation circuit. .

[0008] Such as figure 1 As shown, D5, D6, D7, and D8 form a single-phase bridge rectifier stack, which converts the input alternating current into pulsating direct current and sends it to the next stage circuit. D9, D10, D14, C3, C4, C5 and R1 form a power correction circuit, the output voltage of the rectifie...
