ABSTRACT:
A microprocessor-controlled high voltage sensor circuit controls resonant operation of an induction coil—capacitor circuit. The sensor circuit includes an input that receives a high voltage signal from the induction coil—capacitor circuit, an attenuator coupled to the input, wherein the attenuator reduces the high voltage signal to a low voltage signal, a peak detector coupled to the attenuator, the peak detector that holds the low voltage signal and detects a peak value of the low voltage signal, a clipper circuit that limits an output voltage from the peak detector so as to prevent damage to components of the high voltage sensor circuit, and a linear amplifier that receives the low voltage signal from the clipper circuit and amplifies the low voltage signal for detection of resonance conditions in the induction coil—capacitor circuit by a microprocessor coupled to the high voltage sensor circuit.
