Description

Technical Field

[0001] The utility model relates to the technical field of frequency converters, in particular to a frequency converter with a European structure. Background Art

[0002] The frequency converter is an electric power control device that applies frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. The frequency converter is mainly composed of rectification, filtering, inversion, braking unit, drive unit, detection unit and microprocessing unit.

[0003] Most existing inverters are large in size, making them inconvenient to place side by side and operate and control. When the fan blows air to dissipate heat inside the inverter, dust easily accumulates on the internal components of the inverter after long-term use. The excessive dust corrodes the internal components of the inverter, affecting the service life of the inverter. At the same time, external equipment connects the connecting wires directly to the inverter wiring port. If the user accidentally trips over the wires, the interface may become loose, causing the risk of electric shock. Therefore, a European-style inverter is needed. Utility Model Content
