Braking Solution for VFD System

A VFD braking solution manages regenerative energy from motor deceleration to prevent DC bus overvoltage. Dynamic braking dissipates energy as heat via resistors, offering low cost and high torque. Regenerative braking feeds energy back to the grid, improving efficiency for frequent braking applications like cranes and elevators.

EMC/RFI Products

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 EC Fan

EC fans are widely used in data centers, HVAC systems, and industrial cooling due to their high efficiency, low noise, and intelligent speed control. However, their power electronic drives generate harmonic currents that may affect power quality and system stability. Dedicated EC fan harmonic filters use LC passive filtering technology to reduce harmonics, improve power factor, and enhance power supply reliability.

Harmonic Solution for Medium frequency furnace

Systematically analyze the 5th, 7th, 11th, and 13th characteristic harmonics and reactive power impacts generated by medium-frequency furnaces. Compare mainstream solutions, including passive filters, active power filters (APF), dedicated furnace filters, and multi-pulse rectification, providing selection guidance to improve power factor and power supply stability.

Harmonic Solution for VFD system

Harmonic pollution in variable frequency drive (VFD) systems causes severe hazards to equipment, grids, and production safety. Optimizing power quality and lowering comprehensive costs requires implementing three mainstream mitigation solutions: line reactors, passive filters, and active power filters

Motor Protection solution

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.

Power Supply for Aerospace & Military

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.
