Embodiment Construction

[0012] In order to further understand the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0013] attached by figure 1 It can be seen that: attached figure 1 The single-phase double-switch high-variable voltage regulation AC stabilized power supply with industrial compensation, which consists of high-frequency inverting transformer T1, power frequency compensation transformer T2, two bidirectional switches S1 and S2, one inductor L, and two capacitors C1 Composed of C2 and its control circuit, S1 is composed of 2 diodes D1, D2 and 2 triodes V1, V2. S2 is composed of two unidirectional thyristors V3 and V4 in parallel, and there are DC signals on their trigger poles during the positive and negative half cycles of the power supply. Therefore, in the chopper voltage regulation process, only the on-off ratio of the bidirectional switch S1 can be adjusted to invert the phase and regulate the voltage....

Abstract

The invention belongs to a compensation type alternating-current voltage-stabilized power supply. The power supply comprises a single phase and a three-phase, and the three-phase is formed by connecting three single phases in a star shape. A single-phase double-switch high-variable inverse-modulation power-variable compensation alternating-current voltage-stabilized power supply is composed of a high-frequency inverse-modulation transformer T1, a power frequency compensation transformer T2, two bidirectional switches S1 and S2, an inductor L, two capacitors C1 and C2 and a control circuit. TheS1 is composed of two diodes and two triodes or four diodes and one triode. The S2 is composed of two unidirectional thyristors V3 and V4 which are connected in an anti-parallel mode. Compared with aGong's half-bridge chopping voltage regulation power transformation compensation type alternating current voltage-stabilized power supply invented by the same inventor, by using the power supply of the invention, a high-frequency transformer is used for replacing a power frequency autotransformer with a center tap, a size is small, and weight is light.

Description

[0001] [1] Technical field [0002] The invention relates to an AC chopping, phase-inverting, voltage-regulating and voltage-compensating AC stabilized power supply using a power frequency change compensation transformer. [0003] [2] Background technology [0004] AC chopping control voltage regulation has the advantages of continuous stepless non-contact voltage regulation, high precision, high cost performance, etc. Piezoelectric power supply has the disadvantage of many two-way switches. The double-switch half-bridge chopping control voltage regulation industrial transformer compensation AC regulated power supply invented by the same inventor has reduced two bidirectional switches but added one with a center tap. Auto-inverting transformers have the disadvantages of large volume and heavy weight. [0005] [3] Contents of the invention [0006] The purpose of the present invention is not to invert the phase of the power frequency autotransformer. [0007] In order to achi...
