Abstract

The invention relates to an electric power electronic module of a ship frequency converter, which comprises two intelligent power modules (IPM) arranged on a bracket symmetrically and a group of support capacitors arranged in the bracket, wherein a power bus-bar is fixedly connected with direct current input ends of the intelligent power modules; a high-frequency absorption capacitor, the support capacitors and the power bus-bar are fixedly connected with one another; a buffering resistor is fixed on a radiator on the bracket; and a power filter is arranged on the bracket. The electric power electronic module has the advantages of high power density, small volume, small voltage spike for a direct current bus-bar, high reliability, good maintainability and the like, and is mainly used for a high-power and high power density ship propelling frequency converter.

Description

technical field [0001] The invention relates to a power electronic module of a marine frequency converter, in particular to a power electronic module of a high power density marine high-power frequency converter, and belongs to the technical field of power electronic components. Background technique [0002] With the rapid development of power electronics technology and system integration technology, ship integrated electric propulsion has attracted much attention. Integrated electric propulsion has incomparable advantages over traditional propulsion methods, and it is increasingly used in luxury cruise ships, icebreakers and even military ships. Inverter is one of the core equipments of marine comprehensive electric propulsion. Large foreign manufacturers such as ABB, Alstom, and Siemens have developed power electronic modules for marine inverters. In the existing high-power inverters used in other application fields other than ships, the DC connection between the rectifie...
