| Abstract |
The performance of a conventional shunt active
filter is heavily dependent on accurate current sensing and a
complicated control algorithm. This paper presents an improved
control method for a voltage source active power filter that does
not require any information on the currents to compensate the
harmonics. The operating principles and space-vector control of
the system are presented and analyzed. The control based on the
steady state equations is found to cause dc components to supply
currents. Thus the transient state performance is improved using
a compensation method based on the dynamic model of the
system. Finally, the current sensorless active filter is examined
with simulations and the performance is confirmed with
experiments in the laboratory. |
