Embodiment Construction

[0008] In order to further understand the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0009] Depend on figure 1 It can be seen that:

[0010] 1) A single-switch AC chopping filter voltage regulating circuit is composed of full-control switch S1 chopping, high-frequency inductors L1, L2, L5 and high-frequency capacitors C1~C3, between the two output terminals (3, 6) The output AC voltage U36 is an adjustable voltage with the same waveform as the AC input terminals (1, 2).

[0011] 2) It is composed of full-control switch S2 chopping, high-frequency inductors L3, L4, L5 and high-frequency capacitors C4~C6 to form another single-switch AC chopping filter voltage regulating circuit, at the two output terminals (4, 6 ) between the output AC voltage U46 is the same adjustable voltage as the waveform at both ends of the AC input (1, 2).

[0012] Since the above two AC chopping control voltage reg...

Abstract

A dual-switch chop voltage regulate and compensating AC voltage regulate power supply consists of a power frequency transformer, a high frequency inductor, a high frequency capacitor, A full-control switch and a control circuit thereof, A fully controlled switch S1, Inductor L1, L2, L5 and capacitors C1 to C3 form a single-switch chopper voltage regulating circuit, A fully controlled switch S2, Inductor L3, L4, L5 and capacitors C4 to C3 constitute another single-switch chopper voltage regulating circuit. 2 single switch chop control circuits are connected in parallel, 2 fully-controlled switch S1 and S2 inversely regulate that duty cycle, two non-output common terminals (3, 4) as act as output terminals (3, 4) of the bidirectional circuit, 3 and 4 terminals are connected with that primarywinding W1 of the pow frequency compensation transformer, the secondary winding W2 is connected in series between the AC input terminal 1 and the regulated output terminal 3, and the fully controlledswitches S1 and S2 are each composed of two diodes and two transistors, or are composed of four diodes and one transistor. The supply has the advantages of small volume, light weight and low cost, and has good economic and social benefits.

Description

technical field [0001] The invention relates to an AC chopping control bidirectional voltage regulating circuit and an industrial transformer compensation AC stabilized voltage power supply Background technique [0002] CN204707039 U; CN204707042 U; CN204615661 U; CN20615662 U; CN204615663 U: CN204615666 U and other various four-switch chopping control voltage regulation high-variation compensation AC voltage regulators designed by the same inventor have the defect of many bidirectional electronic switches. Contents of the invention [0003] The AC stabilized power supply needs an AC chopping control voltage regulating circuit that can both step up and step down. The first purpose of the present invention is to provide a dual-switch bidirectional AC chopping control voltage regulating circuit. The second purpose is to design Industrial change compensation type AC regulated power supply. [0004] In order to achieve the above-mentioned first object, the dual-switch AC chop...
