Abstract

The invention relates to a voltage conversion device and a three-phase voltage conversion device, and belongs to the technical field of power electronics. The device comprises: at least a voltage input end and a voltage output end; at least one main magnetic induction assembly, provided with a first notch; at least one auxiliary magnetic induction assembly, provided with a second notch corresponding to the first notch; at least one input coil, connected with the at least one voltage input end; an output coil, connected with the voltage output end; and at least one magnetic induction adjustingassembly, arranged between the first notch and the second notch, can move and used for adjusting the voltage of the voltage output end. Therefore, the movable magnetic induction adjusting assembly isarranged between the first notch and the second notch to change the magnetic path so as to adjust the coupling degree of the output coil and the input coil, online stepless adjustment of the amplitudeand / or the phase of the output voltage can be achieved, the structure is simple, and complex operation of changing connecting wires is avoided.

Description

technical field [0001] The present disclosure relates to the technical field of power electronics, in particular to a voltage conversion device and a three-phase voltage conversion device. Background technique [0002] Since its inception, alternating current has been the most important and irreplaceable form of energy, among which amplitude, phase, and frequency are the three elements that define alternating current. Broadly speaking, any device that changes one or more elements of the output voltage for a given input can be referred to as a voltage conversion device or transformer. At present, transformer devices are widely used in the transmission, transmission, transformation, distribution, and utilization of alternating current to realize the conversion between different voltage amplitudes, phases, and frequencies. In the power transformation and distribution link, it is necessary to adjust the variable ratio to stabilize the output voltage according to the grid voltag...
