Embodiment Construction

[0031] Such as Figure 6 As shown, the present invention provides a hydrogen energy fuel cell air compressor motor controller. The upper box body 1 and the lower box body 4 are relatively covered to form a box body, which plays the role of water cooling and heat dissipation and a component installation base. The input module 3, DC-LINK capacitor 2, IGBT module 5 and output module 6 that constitute the main control circuit are fixed, and the shielding plate 9, control board 8 and low-voltage signal port connector 10 are also fixed; the DC power from the battery pack It flows into the control main circuit through the input module 3, and is output by the output module 6 after inversion; the control board 8 and the IGBT module 5 realize signal intercommunication through the wire harness, and the shielding plate 9 is arranged between the control board 8 and the IGBT module 5 to achieve electromagnetic shielding.

[0032] Such as figure 1 , Figure 6 As shown, the input module 3 ...

Abstract

The invention provides a hydrogen energy fuel cell air compressor motor controller, which comprises a box body. An input module, a DC-LINK capacitor, an IGBT module and an output module which form a control main loop in sequence are mounted in the box body; the input module is provided with a 2PIN high-voltage connector which is upwards arranged on the box body, and the 2PIN high-voltage connectoris electrically connected with the bent upward input end of the input copper bar assembly; a mounting operation hole is formed in one side, corresponding to the input end, of the box body, and a cylindrical anti-falling sheath is inserted into the mounting operation hole; the input copper bar assembly is manufactured in an injection molding mode. A plastic casing and a copper bar are arranged; aforming groove is formed on the plastic casing, a safety capacitor and a magnetic ring are fixed in the forming groove, the safety capacitor and the magnetic ring form a filter circuit, a welding pinis arranged on the copper bar, and the safety capacitor is connected with the welding pin of the copper bar in an electric resistance welding mode. The controller provided by the invention has the advantages of wide voltage and current ranges, high power density and good heat dissipation performance.

Description

technical field [0001] The invention relates to the hydrogen energy automobile industry, in particular to a hydrogen energy fuel cell air compressor motor controller. Background technique [0002] In the case of increasingly scarce oil resources and increasingly serious environmental pollution, the hydrogen energy vehicle industry has also received extensive development and attention. With the continuous development of the hydrogen energy vehicle industry, on the one hand, the interior space of the vehicle is becoming more and more compact, and the power density requirements of the hydrogen energy fuel cell power supply system of the vehicle are getting higher and higher. This requires the air compressor motor controller, which is one of the important components of the hydrogen energy fuel cell, to be as small as possible and have as high a power density as possible to meet the layout space requirements of the vehicle. On the other hand, due to the incomplete development of...
