Abstract

The invention relates to a power system structure which comprises a power module and a structure connected with a system, wherein a direct-current positive busbar is arranged above the power module; a direct-current negative busbar and a main bus copper bar are connected through a transfer copper bar; the structure connected with the system comprises a transfer copper bar nut plate and a compression module direct-current busbar leading-out terminal of the transfer copper bar; an alternating-current copper bar on the rear lower side of the power module is directly connected with an alternating-current copper bar of the system; a bus capacitor passes through a bus capacitor fixing plate, and a bus capacitor clamping plate and a capacitor clamping pull rod are fixed on a module fixing bracket and a water cooling plate; two terminals of the direct-current positive busbar and two terminals of the direct-current negative busbar are upward, are led out and are respectively connected with the main bus copper bar. With the adoption of the system structure and the power module structure provided by the invention, high power density, compact structure and a good water cooling heat dissipation effect of the bus capacitor and an IGBT (Insulated Gate Bipolar Transistor) can be realized; a direct-current copper bar and the alternating-current copper bar of the power module are respectively led out up and down; through a transfer structure, mounting and connection are reliable and convenient, and the characteristics of high power and compact structure are realized.

Description

technical field [0001] The invention relates to a power system structure applied to a high-power converter, including a power module and a system connection structure, and belongs to the mechanical field. Background technique [0002] The invention relates to a structural scheme of a power system. For current high-power converters, the increase in power density leads to larger volume, and the smaller space of the entire system leads to increased difficulty in system connection; the system current is getting larger and larger, requiring must There is a reliable system connection. This requires the power system structure to be very compact, and does not affect the performance of installation and maintenance. Contents of the invention [0003] The invention provides a power system structure, which aims to solve the technical problems of the existing high-power converters with too large volume and small space. [0004] The technical solution of the present invention: a power...
