Abstract:

Voltages up to 10,000 volts or higher must be attenuated and measured to provide control feedback for many applications like medium voltage generators or pulsed power systems. How these medium voltage signals can be conditioned so that they can be input to analog control circuits or analog-to-digital converters is the focus of this thesis. A preconditioner circuit takes as input a medium voltage signal and outputs a low voltage conditioned signal to an analog-to-digital converter. Each of the components of the preconditioner circuit, a voltage divider and an averaging circuit designed with an operational amplifier, contributes to the signal conditioning. The theoretical computations, simulations of the circuit, and experimental data were analyzed for congruence. The 3 dB bandwidth of the experiments frequency response was significantly reduced compared to that of the simulations frequency response because of parasitic capacitances in the circuit board.
