Problems solved by technology

[0005] However, since the cooling air in the series cooling mode does not flow through the inverter unit 41 and the rectifier unit 42 at the same time, the inverter unit 41 and the rectifier unit 42 have different cooling effects
In addition, since the converter has a flat design and a large volume, it is not easy to install and disassemble

Abstract

The embodiment of the invention discloses a converter module, a converter and a converter cooling system. The converter module includes: a rectification unit (11), a DC link unit (12), and an inverter unit (13), and wherein the rectification unit (11) and the inverter unit (13) are located at Upstream of the flow direction of the cooling air flow; the direct link unit (12) is arranged downstream of the flow direction of the cooling air flow. The embodiment of the invention proposes a modular and compact converter module, the rectification unit and the inverter unit have the same cooling effect, and the connection of the DC bus is very convenient.

Description

technical field [0001] The invention relates to the technical field of power semiconductors, in particular to a converter module, a converter and a converter cooling system. Background technique [0002] A converter (Inverter) is an electrical device that changes the voltage, frequency, phase number and other power or characteristics of the power system. It is also called an inverter or a drive and is usually used to control an electric motor. A converter generally includes a rectifier for alternating current to direct current (AC / DC), a direct current link (DC-link) for decoupling and filtering, and an inverter unit for direct current to alternating current (DC / AC). The power conversion function of the converter is realized by a specific circuit topology composed of power semiconductor devices. Power semiconductor devices generate significant heat during operation, and good heat dissipation is required to ensure working performance. [0003] Currently, specific cooling t...
