Abstract

The present invention discloses a driver for a special vehicle. The driver comprises a shell and also comprises a capacitor, an IGBT, a lamination busbar, and a busbar arranged in the shell. The driver also comprises a plug arranged outside the shell. The capacitor is connected with the IGBT in parallel through the lamination busbar, and the lamination busbar is connected to the busbar at the same time, and the external connection of the lamination busbar is realized through the busbar. The plug comprises a configuration plug for an external support capacitor, and the configuration plug for the external support capacitor is connected to the capacitor in parallel through the busbar. According to the driver, the technical problems of large workload of type selection design, expensive test resources, high cost, and no change of a capacitance value of a special vehicle driver can be solved.

Description

technical field [0001] The invention relates to the field of vehicle electrical equipment, in particular to a driver device with an external support capacitor applied to a special vehicle. Background technique [0002] In the prior art, when a DC bus is used for power supply and a driver (DC / AC, DC / AC converter) is used to control the motor to drive the vehicle, matching between the driver and the motor becomes a key issue. According to design experience, the selection of drive power components is relatively easy. According to the formula P=U*I*cosα, the selection of power components can meet the requirements of voltage and current. The combination of voltage and current with different rated points will lead to a relatively large range of power variation. The formula for selecting the reference capacitor is: C≥P / (4ηf s UΔu), when P changes, the capacitance value of the supporting capacitor will also change. When other parameters of the supporting capacitor are determined...
