Abstract

A multifunctional electric energy converter is composed of rectifier, filter, inverter, the differential mode voltage suppressing reactors serially connected to the outputs U, V and W of inverter, and filter capacitor group. Its features are that the output lines V, V and W of inverter are wound on a magnetic ring for isolating HF signals, decreasing output of common-mode voltage and improving output voltage waveform.

Description

technical field

[0001] The invention relates to electrical transmission devices in the field of electrical transmission. Background technique

[0002] Electric energy is widely used in various occasions. With the increasing development of science and technology, people have developed various electric energy transmission devices, such as transformers that change voltage, to achieve Inverters for AC-DC conversion, inverters for changing output frequency, and various active reactive power compensators and energy feedback devices for protecting grid power from pollution. The common disadvantage of these power transmission devices is single function, and the performance cannot fully reach the ideal working state, such as the contradiction between the voltage transformation capacity of the transformer and its own consumable cost, high temperature insulation; the high voltage transmission of the inverter and its own The contradiction between low-voltage power switches and the comm...
