Abstract:
1. A parallel filter circuit for use with an electrical system capable of connecting to a power source and capable of having at least one load connected thereto comprising: a first current sensor capable of sensing at least a current of the electrical system; a first filter capable of producing a first current and connected to the electrical system such that the first filter is connected to the electrical system at a first location downstream of the first current sensor; a second filter capable of producing a second current at a second location downstream of the first current sensor; a second current sensor capable of sensing the first current; a third current sensor capable of sensing the second current; wherein the first current sensor produces a first signal indicating the current of the electrical system and sends the first signal to the first and second filters; wherein the second current sensor produces a second signal indicating the first current and sends the second signal to the first filter; wherein the third current sensor produces a third signal indicating the second current and sends the third signal to the second filter; and wherein the first filter produces the first current and supplies the first current to the electrical system through the first location based at least in part upon the first signal, the second signal and a difference between the first current and the second current, and the second filter produces the second current and supplies the second current to the electric system through the second location based at least in part upon the first signal, the third signal and the difference between the first current and the second current.
