摘要：
A method and system for driving a plurality of transient decoupling capacitors connected in a circuit in order to heat them and to screen them via a thermal image of them. Radio-frequency excitation is provided for the purpose by connecting a pulse driver through an inductive circuit and a series capacitance to supply a driving current to the decoupling capacitors. The inductance is selected to yield resonance at a selected frequency; and the series capacitance provides a voltage divider to help set the frequency and to adjust the level of the drive of the decoupling capacitors.
