Embodiment

[0028] N=4, the phase-shifting transformer includes 4+1 winding transformers, one of which provides 380v conventional power supply, used to provide reactive power compensation power and auxiliary power supply, and can be connected to uninterruptible power supply UPS, when the phase-shifting transformer or power grid fails supply power to the controller;

[0029] Four winding transformers form a 24-pulse phase-shifting transformer, and the phase-shifting angles are 22.5°, 7.5°, -7.5°, -22.5° respectively, and the outputs of the four winding transformers are respectively connected to four rectifier bridges;

[0030] Such as figure 2 As shown, the rectifier module includes four rectifier bridges, which are rectifier bridge 1, rectifier bridge 2, rectifier bridge 3, and rectifier bridge 4. The output of rectifier bridge 1 is connected in parallel with the output of rectifier bridge 3, and the output of rectifier bridge 2 is connected The outputs of four are connected in parallel...

Abstract

The invention discloses an integrated charging system. The integrated charging system comprises a controller, a phase-shifting transformer, a rectifying module, a DC-DC module, a switch array and a charging gun head. The controller is in communication with the DC-DC module. The controller is connected with a dry contact signal of the switch array. The phase-shifting transformer, the rectifying module, the DC-DC module, the switch array and the charging gun head are electrically connected in sequence. Common direct-current bus voltage is provided for a plurality of DC-DC charging modules by thephase-shifting transformer and the rectifying module. The output of DC-DC module is output to a charging gun through a flexible switch array. The controller control switch state, the charging power of each charging gun can be reasonably distributed, the utilization rate of a charger is improved, and the cost is reduced. Meanwhile, an integrated high-power charging system adopts a phase-shifting transformer and a rectifying module, so that the loss is reduced, and the overall efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an integrated charging system. Background technique [0002] With the development of electric vehicles, the charging demand of electric vehicles is increasing day by day. Different battery capacities and charging ratios of electric vehicles have different power requirements for charging devices. The charging device requires various charging powers for different charging requirements. Most of the current charging systems are AC-DC+DC-DC solutions, which have problems such as low reliability, high cost, and low efficiency for high-power charging systems. The charging system proposed by the present invention uses a phase-shifting transformer and a rectifier bridge to form the AC-DC part to reduce the cost of the system. Further, the rectifier bridge in the AC-DC of the present invention adopts uncontrolled rectification to replace the power switch of the original ...
