Abstract

The invention provides a converter. The converter comprises a first converter body, a direct-current control device and a second converter body. The first converter and the second converter are connected with the direct-current control device. The converter provided by the invention has universality and flexibility, can greatly shorten the research and development period and quickly respond to themarket demand, is convenient to hoist on site, is not influenced by the size of an open pore of a courtyard on site, and is convenient to install and transport.

Description

technical field [0001] The invention relates to the technical field of frequency conversion products, in particular to a converter. Background technique [0002] With the continuous development of the new energy field, the demand for emerging industries represented by the recycling of renewable energy is also increasing, and the requirements for the capacity of the AC-DC converter system are also increasing. Limited to the current development level of power semiconductor devices, the power of a single converter module generally does not exceed 1MW. The converter modules mostly adopt the form of double-module parallel connection, and the capacity of a single cabinet is mostly lower than 2MW. In order to meet the high power demand above 2MW, multi-module series-parallel connection is mostly used. For more than 2 modules in series-parallel connection, the cabinet needs to be redesigned. The research and development cycle is long, not versatile and flexible, and the market comp...
