A unit capable of identifying and correcting for a variety of anomalies in AC power systems by using control algorithms driving power converters.
Active filters can be either series or shunt connected devices.
The power obtained by multiplying current amplitude by voltage amplitude in an AC power distribution system. A passive electrical component that stores energy in the form of an electrical charge. A control algorithm used to control the instantaneous current output level of a power converter. When operated in this mode the converter voltage takes whatever value is necessary to force the actual current to equal a reference value. The DC bus is designed to allow limited storage of electrical energy and serves to control the peak voltages seen by IGBT's or other power semiconductors.
