This paper reports on the optimization of an Electro-Optic Voltage Transducer (EOVT) using a VHDL-AMS model. Specifically, two different voltage reconstruction schemes have been assessed: reconstruction using arctangent and using arccosine. Both schemes have been simulated for different applied voltages and phase shift errors between the two electrical signals produced by the EOVT. Despite the high complexity of the device (optical and electronic parts, digital and analogue signal processing), modeling has allowed estimating the performance of the system accurately. This would have been practically impossible through theoretical considerations alone. Results show the arctangent method to outperform arccosine. However, both methods reach the desired accuracy of 0.1% when the phase shift error remains below 6%. © 2011 Published by Elsevier Ltd.
