Description

technical field [0001] The invention relates to the field of IGBT driving technology, in particular to an IGBT driving device integrating a variable and charging system. Background technique [0002] The IGBT driving device is a device that drives the IGBT and regulates its overall performance. It not only affects the dynamic performance of the IGBT, but also affects the cost and reliability of the system. The selection of the driving device and the calculation of the output power determine the reliability of the converter system. Insufficient power or incorrect selection of the driving device may directly cause damage to the IGBT and the driving device. [0003] The current IGBT-based drive devices on the market have the following problems in use: [0004] 1. The traditional IGBT drive device, because the whole device is too large, cannot meet the requirements of the current device compactness, it takes a lot of time for installation, and at the same time increases the ci...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a variable and charging integrated IGBT driving device, which solves the problem that the traditional IGBT driving device cannot meet the requirement of small and compact devices due to the large size of the whole device, and requires a lot of time and energy. At the same time, the loop between the driver IC circuit and the IGBT module is increased, which reduces the driving control effect and complicates the operation. In addition, the traditional IGBT driver installs the heat sink inside the driver, which cannot be well done. The dissipation of heat affects the working efficiency of the device, and excessive heat can easily lead to damage to the IGBT and the drive device
