ABSTRACT:
A high-Q load circuit is matched to a drive circuit with an L-type filter network including series and shunt reactances which are both either inductive or capacitive. While a first of the reactances is effectively removed from the network, the value of the second of the reactances is varied until the impedance magnitude of the load and network, as seen from the drive circuit, reaches a predetermined magnitude, and a predetermined relationship exists for the polarity of the phase of the voltage and current supplied by the drive circuit to the network. When the impedance magnitude seen by looking from the drive circuit into the network reaches the predetermined magnitude and the correct phase polarity exists, the first reactance is reconnected into the network and then varied until a predetermined relationship exists between the phase angle between the voltage and current applied by the drive circuit to the network.
