Problems solved by technology
[0002] The inverter is a device that converts DC power batteries and storage batteries into alternating current, generally 220V, 50Hz sine wave. The existing inverter needs to use multiple single-tube devices in parallel. For example, low-voltage electric vehicles are welded with MOS single-tube On the aluminum substrate, the full-bridge drive uses at least 24 single tubes, and some have a more conservative design and higher power, and even reach 36 or 48. Due to the large number of single tubes, in addition to the large amount of labor in the welding process Unexpectedly, the quality consistency of the welding process caused a very high return rate in the future

The invention belongs to the field of electrical equipment and particularly relates to an integrated module driven inverter, which comprises a micro-control module, a digital signal processing module,a power supply control module and a driving module. The power supply control module is respectively connected with the control module, the digital signal processing module, and the driving module. The digital signal processing module is connected with the micro-control module. The driving module is connected with the digital signal processing module. The driving module is connected with a three-phase motor. The integrated module drives the inverter to integrate a chip into a soft rubber module and is combined with a radiator as a whole, so that the heat conduction effect can be improved. Thearea of a driving circuit is reduced. The area of the radiator is reduced, and the return rate is reduced.
