Title: HIGH VOLTAGE DIRECT CURRENT POWER DISTRIBUTION-BASED ELECTRIC VEHICLE CHARGING STATION
Abstract:
A high voltage direct current power distribution-based electric vehicle charging station, comprising a high voltage circuit breaker, a high voltage direct current conversion device and a charger; a three-phase high voltage input voltage is connected to the high voltage direct current conversion device by means of the high voltage circuit breaker, and the high voltage direct current conversion device converts the three-phase high voltage input alternating current into direct current so as to supply power to the charger. By providing the high voltage direct current conversion device, and using a high voltage withstanding switching device, the invention realizes power factor correction and LLC full-bridge inversion, and converts the three-phase high voltage input alternating current into direct current so as to supply power to the charger, simplifying the design of a direct current charging module, improving the power density of the direct current charging module, improving the stability of the charger, and reducing the construction cost of the charging station.
