[four] appended drawings is the design's Gong Shi paraphase chopping voltage power model main circuit.

[five] embodiment is known by power model main circuit shown in the drawings: it has 2 ac voltage inputs (A1, B1), 2 ac voltage outputs (A2, B2) and 8 control ends, 4 triodes with damper diode (V1～V4) and 2 unidirectional thyristors (V5, V6) to form, and its circuit working principle is as follows:

(a), while requiring input 2 ends (A1, B1) with the output of output 2 ends (A2, B2) same-phase, with 1,3,4 and 5,7,8 control ends, control triode (V1, V4) and thyristor (V5, V6) copped wave and afterflow.

When exchange input A1 end for just, B1 end when bearing, by (3,4) two ends, to the whole positive half cycle of unidirectional thyristor V6, add triggering signal.Positive half cycle alternating current is by copped wave and the unidirectional thyristor V6 afterflow of triode V1 (controlling by 1,3 two ends), output 2 ends (A2, B2) and diode D4, at output 2 ends (A2, B2) output and the synchronous positive half cycle copped wave alternating voltage of input 2 ends (A1, B1).

When interchange, inputting A1 end is timing for negative, B1 hold, by (8,7) two ends, to the whole negative half period of unidirectional thyristor V5, add triggering signal, negative half period alternating current is by copped wave and the unidirectional thyristor D5 afterflow of triode V4 (controlling by 5,7 two ends), output 2 ends (A2, B2) and diode D1, at output 2 ends (A2, B2) output and the synchronous negative half period copped wave alternating voltage of input 2 ends (A1, B1).Therefore, when exchanging input 2 ends (A1, B1) input ac voltage, as long as 6 control ends (1,3,4 and 5,7,8) of logical module are controlled, just can be at output 2 ends (A2, B2) output and input 2 ends (A1, B1) 2 end same-phase copped wave alternating voltages.
