Abstract

The invention relates to a super-high-power wide-range constant power converter, comprising: a first-sixth switch network, a first-sixth resonant network, a transformer module, a rectifier module, a switch module and a high-voltage and low-voltage control module. The first and fourth switch networks are connected in series with each other, the second and fifth switch networks are connected in series with each other, and the third and sixth switch networks are connected in series with each other. The first-sixth switching networks are respectively connected to the respective primary windings of the transformer module via the first-sixth resonant networks. One end of each secondary winding of the transformer module is connected to each other, and the other end is connected to the rectification module; the rectification module respectively outputs the first output voltage and the second output voltage to the switch module, and the high and low voltage control module controls The switch devices in the switch module are switched to realize the ultra-high power and ultra-wide range constant power output of the ultra-high-power wide-range constant power converter.

Description

technical field [0001] The invention relates to the field of power supply modules, and more specifically relates to a super-high-power wide-range constant power converter. Background technique [0002] In today's society, cars are closely related to everyone's life. The development of new energy vehicles is the ultimate way to alleviate the energy crisis and control the problem of urban air quality. The construction of charging facilities such as electric vehicle charging stations is the premise and foundation for the healthy development of the electric vehicle industry. Charging facilities mainly include AC charging piles and DC fast charging piles, and charging power modules are the core components of DC charging piles, which are crucial to promoting the development of new energy vehicles. [0003] The demand for DC fast charging has higher and higher requirements for the power of the charging power module and the constant power of a wide range. On the one hand, the pow...
