A current control method for active filters without detecting current harmonics
説明
In conventional active filters, the load current as well as the active filter output current is detected. Then, the harmonic component of the load current is extracted to create a reference current of the active filter. This paper proposes a novel current control method that requires only detecting the source current. It requires neither detecting the active filter output current nor extracting a harmonic component from the source current. Only two current sensors are required for detecting the current in respective two phases. Thus, the current control system can be greatly simplified.
