Your Leading Active Dynamic Filter Manufacturer in China
Shanghai Nengdu New Energy Co., Ltd. is based in Shanghai, China. As a specialized and sophisticated enterprise, we focus on power quality management and power electronic equipment, integrating R&D, production, sales, and service. With independent core algorithms, our products feature high-precision harmonic compensation, no resonance risk, and excellent adaptability to fluctuating loads. We have obtained ISO9001 certification and multiple authoritative test reports, serving industries, commerce, new energy, data centers, and other fields, with a market reach covering both domestic and overseas customers.
Compared with passive filters, the Active Dynamic Filter realizes real-time dynamic compensation with faster response, covers a wider range of harmonics, avoids resonance for higher safety, works stably under fluctuating loads, and features a smaller size with stronger overall performance.

Working Principle of Our Active Dynamic Filter
The Active Dynamic Filter first samples and monitors the grid current in real time, accurately separating the fundamental wave from harmonic components. It then generates a compensation current with the same amplitude but opposite phase to cancel out the harmonics. As a result, only a clean, stable current is supplied to the load, thereby improving power quality.
It is an advanced power quality device that dynamically suppresses harmonics, compensates reactive power, and balances three-phase current.
It samples grid current in real time, detects harmonics, and outputs reverse compensation current to cancel harmonics automatically.
It is available in wall-mounted, modular, and cabinet-type designs to meet different installation requirements.
Faster response, wider filtering range, no resonance, stable performance under fluctuating loads, and stronger overall performance.
Widely used in industrial plants, data centers, commercial buildings, new energy stations, precision equipment, etc.
