Abstract :
In this paper the control of the current-source active power filter is discussed. A new control system is presented which can be realized without ac current measurements. In current-source converters the ac current measurements are not needed either for protection but the overcurrent can be detected with dc current sensor. For that reason, the ac current sensors can be totally eliminated and the active filter can be realized with single dc current sensor
