Abstract :
Shunt active power filters are connected in parallel with the electricity supply network. If the AC mains has accessible neutral it is desired that the mains harmonics currents zero sequence components are compensated. This can be realised with a four wire PWM voltage converter connected to the network. Its input currents must be controlled. In the paper a space vector based current controller in αβ0 coordinate system is presented. With this current controller positive, negative and zero sequence current harmonics systems can be injected by the converter and thus compensated on the AC mains
