Abstract

The invention provides an auxiliary power module and a circuit. The auxiliary power module comprises an insulated gate bipolar transistor (IGBT), a surge capacitor, a composite busbar and a support capacitor, and is characterized in that the composite busbar comprises an input interface and an output interface; and the support capacitor is connected with the IGBT and the surge capacitor through the composite busbar. According to the invention, the DC input interface and the inverter output interface are integrated into the composite busbar, and the support capacitor is integrated into the auxiliary power module at the same time, so that integration of the auxiliary power module is realized, the stray inductance of the module is reduced, and the performance and the reliability of the auxiliary power module are enhanced.

Description

technical field [0001] The invention relates to power supply structure technology, in particular to an auxiliary power module and a circuit. Background technique [0002] In recent years, with the rapid development of power centralized traction conversion systems in rail transportation, traction control systems, auxiliary power systems, and charger power systems have been integrated into one system, forming a product model of one cabinet and one system. The power module of the auxiliary power system, that is, the auxiliary power module of the converter, is an important part of the auxiliary power system in the power centralized traction conversion system, and its integration directly affects the Auxiliary power system reliability. [0003] At present, the main components of the auxiliary power module include an insulated gate bipolar transistor (Insulated Gate Bipolar Transistor, IGBT), a heat sink, a sudden change capacitor, a composite busbar, a support capacitor, and a s...
