ABSTRACT:
An impedance-matching network for impedance-matching a generator to a load over a wide range of frequencies and impedances. The network includes a first pair of busses across which a plurality of capacitors may be selectively connected to achieve an overall desired value of capacitance for the network, and a second pair of busses across which a plurality of inductors may be selectively connected to achieve an overall desired value of inductance for the network. The network may be controlled so that the capacitance and inductance elements may be arranged with respect to each other and the generator and load in any one of four possible L-type configurations or topologies.
