OEM Modular Design APF Active Power Filter Low Loss for Harmonic Reduction

Shanghai Nengdu New Energy Co., Ltd. is a high-tech and "Little Giant" specialized enterprise focusing on power quality treatment and green new energy technologies. The company’s core products include Advanced Static Var Generators (ASVG/SVG), Active Power Filters (APF), Three-Phase Unbalance Regulators (SPC), etc. We provide low-voltage dynamic reactive power compensation and integrated power quality solutions featuring millisecond-level response, stepless continuous compensation, and modular high reliability. Our products have passed ISO9001 certification and a number of authoritative third-party tests. With more than 20 patents and proprietary core algorithms, we offer customers customized solutions to support grid stability, energy conservation and consumption reduction, as well as efficient grid integration of new energy.

If you are looking for highly reliable and adaptable harmonic suppression equipment, Shanghai NengDu is your preferred partner. We have a team of senior power electronics engineers and a professional R&D and design center that can tailor active power filter solutions based on your grid parameters, load types, and iron core harmonic mitigation requirements.

Active Power Filter APF can eliminate harmonic oscillations and reduce costs. Active Power Filter APF, as a multifunctional solution, can be easily customized to provide power factor improvement, voltage change control, flicker mitigation, and load balancing functions, greatly improving the power quality in the network while reducing harmonic pollution. 

The Active Power Filter APF is an  system designed to eliminate harmonic oscillations and thereby reduce costs. It can be flexibly customized to achieve functions such as power factor improvement and load balancing, which can significantly improve power quality in power grids.

The active harmonic filter adopts a professional optimized modular design. The complete system consists of one or more standard APF filtering modules and an optional intelligent LCD touch screen.Each APF module is an independent and complete harmonic treatment unit, capable of stable standalone operation. Users can freely add or remove modules to flexibly adjust the system’s rated capacity according to on-site load requirements, without modifying the original system.It features the advantages of convenient installation, flexible configuration and strong scalability.

Our streamlined production process delivers both quality and efficiency:
R&D & Customization: Custom design per project requirements
Material Preparation: Certified components and raw materials
Assembly & Testing: Automated assembly and full performance inspection
Packaging & Delivery: Export-standard packaging with complete documents
