Abstract

The invention discloses a full-bridge power module structure based on a crimping type IGCT. The full-bridge power module structure comprises a fixed frame assembly, an IGCT module, an insulating partition plate and a diode module, wherein the insulating partition plate is fixed in the middle of the fixing frame assembly, the IGCT module and the diode module are arranged on the left side and the right side of the insulating partition plate respectively, and the IGCT module and the diode module are detachably connected with the fixing frame assembly in a pressing mode; and IGCT devices of the IGCT module are arranged in a stacked mode, first diode devices of the diode module and the IGCT devices are correspondingly arranged in a stacked mode, and the first diode devices and the corresponding IGCT devices are reversely connected in parallel to form a full-bridge circuit. The modular design is adopted in the modular structure, so the structure is compact and attractive, and circuit distribution is reasonable; and installation and maintenance are convenient.

Description

Technical field[0001]The present invention belongs to the field of power electron power module, and in particular, the present invention relates to a full bridge power module structure based on crimping IGCT.Background technique[0002]Integrated Gate Change Crystal Gate IgCT (Intergrated Gate Commutated Thyristors) was a new power semiconductor device in a giant power electronic device in 1996. IGCT is a gate-off thyristor structure based on the gate, using the integrated gate structure to perform gate hard drive, using a new high-power semiconductor switching device of the buffer layer structure and anode transparent emitter technology, Tong-state characteristics of the thyristor and the switching characteristics of the transistor. IGCT makes a tremendous progress in power, reliability, switching speed, efficiency, cost, weight, and volume, and a new leap to the power electronic device. The medium and high pressure power unit uses IGCT as the core device to electrically, metallurgy,...
