Example Embodiment

[0025] Example 1

[0026] See Figure 2-4 As shown, the present invention provides a multifunctional high-density power unit applied to an on-vehicle energy storage type rail trolley, including: a heat sink 1, the upper part of the heat sink 1 includes three-phase inverter, single-phase chopper and energy control functions The IGBT module 2 is provided with a first frame assembly 3 and a second frame assembly 5 on the side of the heat sink 1. The first frame assembly 3 and the second frame assembly 5 are arranged opposite to each other; a composite busbar 7 is arranged above the IGBT module 2 , Configuration board 12, composite busbar 7 is installed with absorbing capacitor 6; above the composite busbar 7 is provided with a drive board assembly 8, two ends of the drive board assembly 8 and the first frame assembly 3, the second frame assembly 5 Installation and fixation; a power connector 11 is installed on the driving board assembly 8, and a protective plate is arranged above t...

Example Embodiment

[0037] Example 2

[0038] On the basis of Example 1, combine figure 1 , The present invention provides an electrical schematic diagram of a multifunctional high-density power unit applied to an on-vehicle energy storage rail tram. The power unit includes three conversion functions, one is a three-phase inverter function; the other is a single-phase chopping function; The third is the energy control function. Among them, the three-phase inverter function is to convert DC power into AC power for use by AC motors, the chopping function is to feed back and consume energy when the train is braking; the energy control function is to control the flow direction of electrical energy so that the electrical energy flows in the required direction .

[0039] according to figure 1 The principle shows that if the selection of IGBT considers a single tube, 10 IGBTs or diodes are required for layout and calculation, the power density is high, and the radiator area is too large. Therefore, when se...

Abstract

The invention belongs to the technical field of guide rail tramcars, relates to a power unit, in particular to a multifunctional high-density power unit applied to a vehicle-mounted energy storage type guide rail tramcar. The power unit comprises a heat dissipation device, and an IGBT (Insulated Gate Bipolar Translator) module with the functions of three-phase inversion, single-phase chopping andenergy control is arranged above the heat dissipation device. A first frame component and a second frame component are arranged at side edges of the heat dissipation device; a composite busbar and a configuration board are arranged above the IGBT module. An absorption capacitor is installed on the composite busbar. A driving plate assembly is arranged above the composite busbar, and the two end parts of the driving plate assembly are fixedly mounted with the first frame assembly and the second frame assembly respectively; a power connector is installed on the driving plate assembly, and a protection plate is arranged above the driving plate assembly. Through the design of an IGBT structure packaged by a bridge arm, the whole main circuit has the functions of three-phase inversion, single-phase chopping and energy control, and the whole power unit has the characteristics of high density and high space utilization rate.

Description

technical field [0001] The invention belongs to the technical field of guide rail cars, and relates to a power unit, in particular to a multifunctional high-density power unit applied to a vehicle-mounted energy storage type guide rail car. Background technique [0002] With the development of power electronic technology, the power electronic conversion system puts forward higher requirements for efficiency and volume. On the one hand, it is hoped to integrate all power devices into one power unit; on the other hand, it is hoped that the integrated power unit should be as lightweight and miniaturized as possible; how to balance these two requirements is the direction of all converter technology research. [0003] At present, in the converter cabinet, the function of the power unit is relatively single, or only has the rectification function, or the inverter function, or the chopping function, and the function conversion can only be completed by external electrical connection...
