Frequency converter (VFD) is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply. The frequency converter mainly consists of rectifier (AC to DC), filter, inverter (DC to AC), braking unit, driving unit, detection unit, microprocessor unit, etc. The frequency converter adjusts the voltage and frequency of the output power supply by breaking the internal IGBT, providing the required power voltage according to the actual needs of the motor, thereby achieving the goal of energy conservation and speed regulation.

The heat dissipation of frequency converters has a huge impact on their performance and service life. A good heat dissipation solution is undoubtedly important for frequency converters, especially in fiercely competitive situations. Good heat dissipation can improve the quality and competitiveness of frequency converters. Over the years, Yaofeng has provided advanced heat dissipation technology and services to numerous frequency converter manufacturers, tailoring heat dissipation solutions for customer frequency converter products, and providing effective technical support such as thermal simulation, thermal simulation, and thermal testing to ensure the stable performance of frequency converter products.
