Overview of APF Active Power Filter Products
       Active Power Filter (APF) is connected to the power grid in parallel. Through real-time detection of the harmonic and reactive components of the load, and using PWM transformation technology, the harmonic and reactive components are injected into the power supply and distribution system with the same magnitude and opposite direction of the current. It can suppress harmonics and compensate reactive power dynamically.


Performance Characteristics of APF Active Power Filter   
    1. It can compensate 2-50 harmonics or select specific harmonics to compensate separately.
    2. Flexible compensation methods: only compensating harmonics; harmonics and reactive power compensation; only compensating reactive pow 
    3. It has remote communication interface and can be monitored by PC in real time. Intelligent control circuit, high reliability.
    4. Advanced power conversion technology, flexible compensation mode and simple operation.
    5. The equipment has high reliability and can withstand high temperature, high charged dust and heavy corrosion environment.
