Abstract
An apparatus and method utilizing a sweep-frequency, high voltage generator coupled to an applicator gun for feeding electric power into pest-infested dielectrics, for example termite-infested wood. Utilizing a conventional line frequency of 120 or 60 Hz, the generator produces 140 kilovolts propagated within a spectral band ranging from 15 to 120 kHz and rich in harmonics. Output is discharged through a high-voltage energy storage capacitor charged using an insulated gate bipolar transistor driven by a variable frequency inductively coupled multivibrator. The output voltages penetrate dielectrics and electrocute the pests inside. The invention is effective against insects having hard exoskeletons comprised substantially of cuticulin, chitin, and sclerotin.
