Abstract

The invention provides a modularized power unit which comprises an insulative outer shell where power devices are arranged in a sealed mode, a drive circuit box where a drive circuit board is arranged in a sealed mode and a low-inductance busbar with multiple wiring terminals. The low-inductance busbar is fixed on the power devices in the insulative outer shell and electrically connected with the power devices. The drive circuit box is fixed on the insulative outer shell and the drive circuit board is provided with a set of control output ends which are connected with the power devices in the insulative outer shell. The invention further provides the modularized power unit where two power devices are arranged in a sealed mode and an inverter corresponding to the modularized power unit. The power devices are arranged in a sealed and isolated mode and a modularized structure is used so as to achieve a hardware topology structure of an inverting circuit in the industrial field. Maximum multiplexing of technology and high reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of frequency conversion, and more specifically relates to a modular power unit used in a high-power inverter. Background technique [0002] With the rapid development of power electronics technology in the field of industrial automation, frequency conversion and speed regulation technology has been widely used in recent years. In addition to good control performance, users have a greater understanding of the size, maintainability, modular design and safety of frequency converters. high demands. [0003] Existing modular design power modules include drawer-type horizontal modules and load-bearing book-type modules. Two invention patent applications with application numbers 200810000169.1 and 201210109947.7 respectively disclose the above two power modules. These two types of power modules are formed by integrating components such as radiators, high-voltage IGBTs, high-voltage low-inductance busbars, AC busba...
