Product Description

PRODUCT INTRODUCTION:
        WT-APF active power filter (APF) is a new type of power electronic device used to dynamically suppress harmonics and compensate reactive power. It detects the load current with sampling circuit, extracts the harmonic component in the load current through internal DSP calculation, and drives IGBT, The control inverter generates a harmonic current which is equal to the harmonic current of the load and in the opposite direction and injects into the power grid to achieve the purpose of filtering. According to the same principle, APF can also compensate the negative sequence current component of asymmetric three-phase circuit, to realize the three-phase unbalance compensation and reactive power compensation.
        Comprehensive functions: intelligent harmonic filtering, dynamic reactive power compensation and three-phase load balancing can be realized at the same time
        Excellent performance: with nearly perfect harmonic filtering effect and continuous dynamic reactive power compensation, the power factor is increased to more than 0.95 to ensure load balance and safe operation of equipment
        Advanced technology: continuous, dynamic tracking compensation, 40us response to load change, 10ms compensation. The filtering performance is not affected by the system impedance. The harmonic compensation characteristics are not affected by the frequency change of the power grid, and the compensation ability is not limited by the grid voltage.
