Problems solved by technology

But the electromagnetic operating environment of the power unit is getting worse and worse
With the increase of total voltage level and total output power, the spatial distribution of interference energy inside each standard power unit increases, the aperiodicity of time distribution increases, the spectral bandwidth of interference frequency increases, and the number of emission interference sources increases correspondingly. Its harsh electromagnetic compatibility envir

Abstract

This invention provides one high voltage transducer power unit, which comprises shell, function parts, control board, capacitor array and dissipation part, wherein, capacitor array is put on unit bottom; dissipation device is distributed on one side of capacitor array and other side with control board; there is shield board between control board and power parts with power parts on dissipation surface to connect parts through copper band.

Description

(1) Technical field [0001] The invention relates to a power electronic commutation device, specifically a system for realizing power conversion in a high-voltage frequency converter of the multi-level unit series voltage source type, and is called a commutation power unit in engineering. (2) Background technology [0002] my country's motor design concept and technology were learned from the Soviet Union in the 1950s, leaving a large margin in industrial design, and the power utilization rate of the system is low during operation. There is a great demand for energy saving in the application of high-voltage frequency converters in the power market. [0003] According to the national report "Research on the Ways and Countermeasures of Motor Speed ​​Control Technology Industrialization", 66% of China's total power generation is consumed on motors. At present, the total installed capacity of motors in China has exceeded 400,000 megawatts, and high-voltage motors account for abo...
