Abstract

The embodiment of the invention provides a high voltage direct current charger for charging power batteries with high direct current with high output capacity. The charger comprises a high voltage pulse output module, an alternating current-alternating current conversion module, an alternating current-direct current conversion module and a first master control module, wherein the high voltage pulse output module is used for converting three-phase alternating current to high voltage pulse and outputting the high voltage pulse; the alternating current-alternating current conversion module is connected with the output end of the high voltage pulse output module and is used for boosting the high voltage pulse output by the high voltage pulse output module and then outputting high voltage alternating current; the alternating current-direct current conversion module is connected with the output end of the alternating current-alternating current conversion module and is used for converting the high voltage alternating current output by the alternating current-alternating current conversion module to high voltage direct current and outputting the high voltage direct current; and the first master control module is connected with the alternating current-direct current conversion module and the high voltage pulse output module respectively and is used for receiving the voltage and current sampling feedback signals output by the alternating current-direct current conversion module and then controlling the high voltage pulse output module.

Description

technical field [0001] The invention relates to the field of power supplies, in particular to a high-voltage DC charger. Background technique [0002] Electric buses, electric buses and electric passenger cars are currently more energy-saving and environmentally friendly green travel vehicles. The difference between these electric vehicles and oil-powered vehicles is that they are equipped with power batteries. The power storage battery of the electric tool can be charged at the starting point and the ending point. As the operating mileage increases, electric vehicles may also need to be charged midway, and the charging station is the place to provide this function. [0003] The main equipment of the charging station is the charger, which is a power conversion device with specific functions used to charge the power battery. The charging mode of the charger is divided into DC charging mode and AC charging mode. Among them, the DC charging mode is a mode in which the control...
