Problems solved by technology

[0003] Among them, the single-winding transformer can only provide one voltage, and cannot adjust the voltage
The multi-winding transformer can only output several fixed voltages, the voltage range is narrow, and it cannot be flexibly adjusted, which is inconvenient to use
However, the manufacturing process of the autotransformer voltage regulator is complicated and the cost is high. There is also an electrical connection between the primary and secondary windings in addition to the connection of the magnetic field, so it is easy to cause electric shock to personnel and damage to equipment due to overvoltage.

Embodiment Construction

[0015] figure 1 It is a structural schematic diagram of a voltage regulating device in a specific embodiment of the present invention. Such as figure 1 As shown, the voltage regulating device includes: a transformer, a plurality of secondary side air switches, a main power supply air switch, an AC output air switch, a DC output air switch, a rectifier bridge, and an auto-coupler.

[0016] The design capacity of the transformer Tr is usually calculated according to the average value of the transformer's secondary power and primary power.

[0017] In this embodiment, for the convenience of calculation, the load is purely resistive, and there are eight windings on the secondary side of the transformer Tr, so the total output power of the secondary is

[0018] P 2 =U 21 I 21 +U 22 I 22 +U 23 I 23 +...+U 28 I 28

[0019] Where P2 is the total secondary output power of the transformer. u 21 =1V, U 22 = 2V, U 23 = 4V, U 24 =8V, U 25 =16V, U 26 =32V, U 27 =64V, U ...

Abstract

The invention discloses an AC and DC voltage regulation device which comprises a transformer, a plurality of secondary voltage regulation air switches, a main power air switch, an AC output air switch, a DC output air switch, a rectifier bridge and an autotransformer, wherein the transformer is provided with a primary winding and a secondary winding, the main power air switch is connected with the primary winding in series, the secondary winding comprises a plurality of sub windings, and each sub winding is connected with one voltage regulation air switch; when each secondary voltage regulation air switch is in off position, the sub winding connected with the secondary voltage regulation air switch is disconnected from the secondary winding; when each secondary voltage regulation air switch is in on position, the sub winding connected with the secondary voltage regulation air switch is connected to the secondary winding; the rectifier bridge is connected with the output end of the secondary winding of the transformer in parallel; the AC output air switch is connected with the secondary winding in series; and the DC output air switch is connected with the DC side of the rectifier bridge in series. The invention provides a multi-winding transformer which can realize various flexible secondary output voltages.

Description

technical field [0001] The invention relates to a voltage regulating device. Background technique [0002] In daily life and electrical maintenance, AC or DC power supplies of different voltage levels are often used. In the prior art: there are several forms of voltage regulating devices as follows: single winding transformer; multi-winding transformer; autotransformer voltage regulating device. [0003] Among them, the single-winding transformer can only provide one voltage, and cannot adjust the voltage. The multi-winding transformer can only output several fixed voltages, the voltage range is narrow, and it cannot be flexibly adjusted, which is inconvenient to use. However, the manufacturing process of the autotransformer voltage regulator is complicated and the cost is high. In addition to the connection of the magnetic field, there is also an electrical connection between the primary and secondary windings, so it is easy to cause electric shock to personnel and damage...
