Abstract
In one embodiment, the present disclosure is directed to a method for performing diagnostics on a matching network that utilizes an electronically variable capacitor (EVC). According to the method, all the discrete capacitors of the EVC are switched out. At a first node, a parameter associated with a current flowing between a power supply and one or more of the switches of the discrete capacitors is measured. The method then switches in, one at a time, each discrete capacitor of the EVC. Upon the switching in of each discrete capacitor, the method remeasures the parameter at the first node and determines whether a change to the parameter at the first node is within a predetermined range to determine whether the corresponding switch, driver circuit, or filter of the discrete capacitor most recently switch in has failed.
