GALVANIC ISOLATED CERAMIC BASED VOLTAGE SENSORS |
摘要 |
A galvanically isolated voltage sensor is provided which includes a mechanically integral piezoelectric transformer assembly coupled to a modulation circuit. The modulation circuit receives a source voltage signal to be measured and modulates that signal at a frequency equal to a resonance frequency of the transformer assembly and transmits the modulated to signal to the transformer assembly. The transformer assembly generates an output signal that is identical to the modulated signal subject to the transformer gain. The output signal is then demodulated and filtered so as to recreate the source voltage signal for analysis. |
