Embodiment Construction

[0020] The integrated on-board charger of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, the high-voltage battery 1 bus is connected to the motor controller 2 bus. The motor controller consists of 6 switch tubes to form 3 pairs of half-bridges, and each switch tube is connected in parallel with a diode. The inverter is realized by controlling the sequence of three groups of half-bridges.

[0022] Such as figure 2 , image 3 As shown, the rectifier bridge D7 is connected to the filter capacitor C2 after rectifying the mains power. The positive pole of the filter capacitor C2 is connected to the center point of the three sets of windings of the motor, and the negative pole of the filter capacitor C2 is connected to the negative pole of the busbar (BUS-) through the first rectifier switch tube Q7. The negative electrode of the bus bar is connected to the positive electrode of...

Abstract

The invention discloses an integrated vehicle-mounted charger. The integrated vehicle-mounted charger comprises a power supply, a controller and a motor that are connected mutually, wherein the three-phase winding of the motor is connected with a rectifier bridge D7; the positive electrode of a capacitor C2 is connected with the central point of the three-phase winding of the motor; the negative electrode of the capacitor C2 is connected with the negative electrode of a bus of the controller through a first rectifying switch tube Q7; and the negative electrode of the bus of the controller is connected with the positive electrode of the capacitor C2 through a diode D8. The integrated vehicle-mounted charger can save cost and space volume, improve charging efficiency and can realize quicker charge.

Description

technical field [0001] The invention relates to the field of electricity, in particular to an integrated on-board charger suitable for new energy vehicles, especially an integrated on-board charger. Background technique [0002] Petroleum is one of the most important primary energy sources in the world at present. With the development of economy, people's demand for petroleum is increasing day by day. Due to the depletion of petroleum resources and the increasing environmental pollution, people began to develop clean and renewable energy. In the field of automobiles, replacing petroleum with electric energy as the driving energy will be the development trend of new energy vehicles in the future. At present, the new energy vehicles on the market are mainly hybrid and pure electric vehicles, and these vehicles need to frequently charge the vehicle power supply and power battery. However, the current charging devices are slow and inefficient, and cannot meet the requirements ...
