Classification: CPC H | IPC H

Claim 16:
17. A method for filtering power on a power system, the method comprising:
receiving a measurement of a load current;
receiving a state of charge of a primary energy storage device, the primary energy storage device being electrically coupled to an active filter system bus to filter power delivered to the active filter system bus via charge and discharge of the primary energy storage device;
controlling a supplemental energy storage device of a shunt active filter electrically coupled to the active filter system bus to perform an active shunt operation to filter the power on the active filter system bus, wherein shunt active filter and the primary energy storage device are controlled to operate collaboratively to perform filtering on the active filter system bus; and
controlling, by control circuitry, a converter of an active filter system to condition power drawn from a generator to create a filtered load on the active filter system bus based on programmable active filter controls, the programmable active filter controls being based on the measurement of a load current and the state of charge of the primary energy storage device, the converter being electrically coupled between the generator and the active filter system bus such that source current from the generator passes through the converter.
