Problems solved by technology

Parallel connection of resistance-capacitance absorption circuit on each switching device is a feasible method, but the increase of components will cause the system reliability to drop, and the internal temperature rise of the case caused by the power resistor heating will also become a big problem

Embodiment Construction

[0028] An insulated gate bipolar transistor three-level power cabinet according to the present invention includes a cabinet body 1 and six sets of inverter / rectifier power modules 2 installed inside the cabinet body 1, three sets of DC filter capacitors 3 and overlapping busbars 4, like figure 1 shown. According to the electrical schematic diagram, the position of each power electronic component is reasonably arranged to form an insulated gate bipolar transistor three-level power module. The specific arrangement is as follows:

[0029] The interior of the cabinet 1 is divided into upper, middle and lower layers from top to bottom, and is divided into front, middle and rear in the depth direction; each layer in the cabinet is arranged with two groups of inverter / rectifiers in the same layout The power module 2 and a set of DC filter capacitors 3, two sets of inverter / rectifier power modules 2 are respectively located on the left and right sides of the DC filter capacitor 3, an...

Abstract

The invention relates to an insulated gate bipolar transistor three-level power cabinet comprising a cabinet body as well as six groups of inversion / rectification power modules, three groups of direct-current filter capacitors and a lapping busbar installed inside the cabinet body. The inside of the cabinet body is internally divided into an upper layer, a middle layer and a lower layer from top to bottom and a front, a middle and a rear in the depth direction. Every two groups of inversion / rectification power modules and one group of direct-current filter capacitors are disposed on each layer in the cabinet body in the same layout and all positioned at the front positions in the middle of the cabinet body. The six groups of inversion / rectification power modules are all cooled through water-cooled heat sinks, and the water-cooled heat sinks are connected with an external circulating cooling water channel through a water-channel main tube in the inner front of the cabinet body. The lapping busbar is installed in the rear of the cabinet body and comprises stacked busbar bodies A installed on each group of inversion / rectification power modules and stacked busbar bodies B installed on each group of direct-current filter capacitors. The insulated gate bipolar transistor three-level power cabinet has the advantages of less circuit stray inductance and high output capacity, and convenience in installation and connection and applicability to different engineering requirements as being of a modular structure.

Description
