Problems solved by technology

However, as a conventional energy source, the imbalance between oil resources and its consumption is becoming more and more serious. It is no exaggeration to say that based on the current consumption rate of oil resources, in the near future, oil resources will be exhausted due to and will disappear from us
In addition, when petroleum fuel is used as a power source, it will emit a variety of toxic gases, and may also cause many environmental pollution problems, such as the greenhouse effect, acid rain or photochemical smog, etc.

Abstract

The invention provides an alternating current (AC) to direct current (DC) power converter, which comprises a phase-shifting transformer, at least one rectifier group and at least one DC-DC converter, wherein the phase-shifting transformer is provided with a primary winding and at least one secondary winding; at least one secondary winding is set as at least one winding unit; each rectifier group is provided with at least one rectifier; each rectifier is electrically connected to the secondary winding in the corresponding winding unit; and at least one DC-DC converter is electrically connected to the corresponding rectifier group and outputs predetermined DC voltage. Correspondingly, the invention also provides a DC charging station. By the invention, the phase-shifting transformer is provided with at least one secondary winding which is set as at least one winding unit, so different phase-shifting angles can be provided according to the actual quantity of windings in each winding unit, harmonic components in current are decreased, and power factors of a system are increased.

Description

technical field [0001] The invention relates to power electronic conversion technology, in particular to an AC-DC power converter with high power factor. Background technique [0002] As we all know, most of the current cars generally use oil as a power source. However, as a conventional energy source, the imbalance between oil resources and its consumption is becoming more and more serious. It is no exaggeration to say that based on the current consumption rate of oil resources, in the near future, oil resources will be exhausted due to And will disappear from us. In addition, when petroleum fuel is used as a power source, it will emit a variety of toxic gases, and may also cause many environmental pollution problems, such as the greenhouse effect, acid rain or photochemical smog. [0003] With the development of science and technology and the deepening of new energy research, people pay more and more attention to the concept of energy saving and environmental protection ...
