A systematic introduction to the core principles and importance of EMC, outlining strategies for interference source control, transmission path blocking, and sensitive device protection, with a focus on the critical role of EMC filters in improving system reliability and regulatory compliance.

Harmonic Solution for Medium frequency furnace

Harmonic Filter

Long cable runs driven by variable frequency drives (VFDs) can cause voltage distortion, peak over voltage, and high-order harmonics, leading to cable aging, motor insulation failure, overheating, and bearing damage. This shortens equipment lifespan, reduces system efficiency, and increases failure rates and maintenance costs.

The 400Hz medium-frequency power supply system has gradually become an important standard in aviation power systems, and the 400Hz transformer is a key core device for achieving voltage conversion and electrical isolation within this system. By increasing the operating frequency, 400Hz transformers can significantly reduce equipment size and weight while improving power density, thereby meeting the stringent requirements of modern aviation and military equipment for power supply systems.
