Active Power Filter

Active Power Filter

Wt-apf active power filter (abbreviated as APF) is a new power electronic device used to dynamically suppress harmonics and compensate reactive power. It uses current to detect the load current, extracts the harmonic components in the load current through internal GSP calculation, and controls the inverter to generate a harmonic current equal to the load harmonic current and in the opposite direction by driving IGBT to inject it into the power grid, Achieve the purpose of filtering. According to the same principle, APF can also compensate the negative sequence current component of asymmetric three-phase circuit and realize the functions of three-phase imbalance compensation and reactive power compensation.
