[one] technical field the present invention relates to AC chopping regulating circuit, and the alternating voltage especially relating to AC chopping voltage output two ends can positive direction export, the AC chopping regulating circuit that can export in the other direction again.

[two] the AC chopping regulating circuit that background technology is present can only export the AC chopping voltage identical with input ac voltage phase place, when it is for high-power compensation type AC regulated power supply, paraphase electronic switch must be increased before AC-input voltage or after interchange output chopping voltage and could realize 2 directions adjustment bucking voltages, last year, same inventor invented a kind of AC chopping bidirectional pressure regulating circuit realizing 2 directions adjustment bucking voltages without electronic switch commutation, but 1 must be had before alternating-current chopper circuit to provide two AC power with centre tapped autotransformer, 201510173812.0) and hand over bridge-type copped wave bidirectional pressure regulating circuit (application number: 20151017381.2) on April 6th, 2015, same inventor applied for bridge-type AC chopping bidirectional pressure regulating circuit (application number:, they also also exist the problem also being needed to convert bidirectional electronic switch by forward pressure regulation to anti-phase pressure regulation.

[three] object of summary of the invention the design is that 2 the bridge-type AC chopping bidirectional pressure regulating circuit solving same inventor all will convert the bidirectional pressure regulating problem that master control, afterflow and short circuit 3 bidirectional electronic switch could realize alternating voltage.

Two AC chopping bidirectional pressure regulating devices of the design, by choke-condenser filter L1C1 and L2C2, 4 bidirectional electronic switch S1 ~ S4 and control circuit composition thereof, it is characterized in that: 4 bidirectional electronic switch S1 ~ S4 are made up of 4 diodes and 1 triode, by master control bidirectional electronic switch S1, afterflow bidirectional electronic switch S2 and choke-condenser filter L1C1 forms the 1st alternating-current chopper circuit, by master control bidirectional electronic switch S3, afterflow bidirectional electronic switch S4 and choke-condenser filter L2C2 forms the 2nd alternating-current chopper circuit, the make-to-break ratio of 2 master control bidirectional electronic switch S1 and S3 regulates direction contrary, there are 2 ac voltage inputs (1, 2), 2 ac voltage outputs (3, 4), oppositely the make-to-break ratio of adjustment 2 master control bidirectional electronic switch S1 and S3 just can at the not common voltage output end (3 of 2 AC chopping regulating circuits simultaneously, 4) export and 2 ac voltage inputs (1, 2) the adjustable AC chopping voltage of same-phase or antiphase.1st AC chopping regulating circuit is identical with the employing chopping frequency of the 2nd AC chopping regulating circuit, and copped wave make-to-break ratio rightabout regulates.
