Embodiment 1
[0021] Such as figure 1 As shown, a phase-shifted output control circuit of the present invention includes: a phase-shifted trigger pulse signal drive circuit, the output end of the phase-shifted trigger pulse signal drive circuit is connected to the common cathode of the rectifier bridge BR1, and the rectifier bridge BR1 is also connected respectively SCR and zero point acquisition circuit.
[0022] When the phase shift trigger pulse PULSE is high, the phase shift trigger pulse signal drive circuit outputs a low level to the common cathode of the rectifier bridge BR1 to trigger the conduction of the thyristor, and the mains voltage across the thyristor is 0V;
[0023] When the phase-shift trigger pulse PULSE is low, the phase-shift trigger pulse signal drive circuit has no output, and the thyristor is cut off, that is, both ends of the thyristor can restore the mains voltage, and when the mains voltage is in the positive half cycle, drive zero point acquisition The circuit obtains...
Embodiment 2
[0035] On the basis of Embodiment 1, Embodiment 2 provides a working method of a phase shift output control circuit.
[0036] The phase shift output control circuit is as described in the first embodiment.
[0037] Such as figure 1 with figure 2 As shown, the working method includes:
[0038] When the phase-shift trigger pulse PULSE is at a high level, the phase-shift trigger pulse signal driving circuit outputs a low level to the common cathode of the rectifier bridge BR1 to trigger the conduction of the thyristor; and
[0039] When the phase-shift trigger pulse PULSE is low, the phase-shift trigger pulse signal drive circuit has no output, and the thyristor is cut off, that is, both ends of the thyristor can restore the mains voltage, and when the mains voltage is in the positive half cycle, drive zero point acquisition The circuit obtains the zero acquisition signal ZERO-CHk.
