Abstract

The invention particularly relates to a power adjusting power supply which comprises an A phase, a B phase, a C phase and a trigger board, the trigger board is provided with a first adjusting circuit,a second adjusting circuit and a third adjusting circuit, one end of the A phase is connected with one end of the first adjusting circuit, one end of the B phase is connected with one end of the second adjusting circuit, and one end of the C phase is connected with one end of the third adjusting circuit. The other end of the first adjusting circuit is connected to the common end between one end of the B phase and the second adjusting circuit, the other end of the second adjusting circuit is connected to the common end between one end of the C phase and the third adjusting circuit, and the first adjusting circuit is provided with a controller used for controlling the working state of the first adjusting circuit. The controller is connected with the second adjusting circuit and the third adjusting circuit. The beneficial effects are that the first adjusting circuit, the second adjusting circuit, the third adjusting circuit and the controller are combined for use, the power supply is controlled and adjusted, and the control is more accurate.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a power regulation power supply. Background technique [0002] The existing power-adjusting power supply uses three phases as a group to control and adjust the power supply, and the distortion rate of the total harmonic current is high, which affects the quality of power transmission in the grid. In addition, the power factor is low, resulting in low transmission efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a power regulation power supply capable of implementing three-phase control and three groups, controlling and regulating the power supply, and more precisely in terms of control. [0004] A power regulation power supply described in the present invention includes phase A, phase B and phase C, and is characterized in that it also includes a trigger boar...
