ABSTRACT:
An electrical circuit incorporating an improved diode expander network for an EMAT having a coil and a radio frequency power source which emits radio frequency power, and which blocks noise and interference while having the ability to operate at high frequencies and high current/power levels. A matching transformer having a primary side is operatively connected to the radio frequency source for receiving the radio frequency power. The transformer also has a secondary side having a first leg and a second leg. The matching transformer is normally a step-down transformer. A diode expander network is provided having a first pair of composite diodes connected in parallel with respect to each other to the first leg of the transformer, and a second pair of composite diodes connected in parallel with respect to each other to the second leg of the transformer. Each composite diode has a plurality of diodes arranged in a series and parallel relationship. One of the composite diodes in each pair is arranged to conduct electricity therethrough in a first direction while the other composite diode in each pair is arranged to conduct electricity therethrough in a second direction, opposite to the first direction.
