Product Description：
1. Fast response capability: advanced algorithms make dynamic response time less than 1ms and transient response time less than 100s;
2. High reliability: multi-layer software and hardware dual protection system with automatic disconnection from the grid function;
3. Large-capacity compensation capability: The compensation capability of active power filters is limited by the capacity of power modules (IGBTs), making it difficult to compensate for large-capacity harmonics. This product can be connected to cabinets without restrictions, making it possible to compensate for large-capacity harmonics and reducing costs.
4. Double closed-loop control technology: the outer loop is a DC voltage control loop, and the inner loop is an AC current control loop;
5. Simple operation method and structure: The operation is simple, just connect the load to the system, no other operations are required. The internal structure is simple, the converter is modular, easy to install and maintain, and after connecting to the system, it can operate normally without human intervention.

The active power filter device is connected to the power grid in parallel, and monitors the load current in real time through a high-precision sampling CT. After converting it into a signal readable by a digital processor, it goes through a series of operations and uses PWM modulation to control the core intelligent power module to output a current that is equal to the harmonic component and opposite in phase, thereby achieving the purpose of eliminating harmonics and purifying the power grid.
