Abstract

The present invention relates to a valve group charging device and a valve group charging control method. The device comprises a printed circuit board, a controller, a valve group to be charged, a power switch and a charging power supply, the valve group to be charged, the power switch and the charging power supply are arranged on the printed circuit board, the printed circuit board is provided with an optical fiber interface, the valve group to be charged comprises at least two charging sub modules connected in parallel or in series, each charging sub module is provided with a charging circuit, the controller communicates with the charging sub modules through the optical fiber interface to send charging control signals to each charging sub module by turns, and the charging sub modules respond to the charging control signals to start corresponding charging circuits. The valve group charging device and the valve group charging control method can charge the sub modules alternately with no need for charging all the sub modules at one time so that a high charging voltage is not required, the output capacity of the charging power supply is reduced and the charging cost is reduced.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a valve group charging device and a valve group charging control method. Background technique [0002] The modular multilevel converter is composed of multiple sub-modules with the same structure cascaded. Among them, the valve group is the main component of the modular multilevel voltage source converter, mainly composed of semiconductor devices that can be turned off composed of sub-modules. [0003] Since the converter station requires extremely high DC charging voltage when charging on the DC side, for a test platform with multiple valve groups, the charging power supply needs to have a high output capacity, and the cost is relatively high. Contents of the invention [0004] Based on this, it is necessary to provide a valve group charging device and a valve group charging control method to solve the problem of high charging cost of a multi-valve group test platfo...
