Abstract:
The Pulsed Electroacoustic method has been widely
used in research labs and industries for space charge
measurement for quite some time. Due to its robustness and
simplicity it has attracted great attention of researchers.
Various models of PEA system have been reported using
numerical simulation and COM SOL to address issues related to
charge signal. Recently, the authors have reported a PSpice
model of PEA system to address some design related issues.
This PSpice model utilizes analogy between electromagnetic
wave propagation in transmission lines and acoustic wave
propagation in solids. In the present work the authors have
modeled amplifier response which was not reported in their
previous work. It explains the signal distortion when an
amplifier is connected in the PEA setup. Wherever possible, the
simulated results have been compared with the experimental
results and found to be satisfactory.
