This thesis investigates the likelihood of PD behavior in HV PCBs and evaluates the suitability of existing design guidance for avoiding this behavior in the implementation of HV PCBs. As part of this analysis, five PCB test subjects were designed and evaluated using both experimental procedures and finite-element (FE) simulations. Experimental measurements were conducted using a standard-based 60 Hz AC voltage stimulus to determine the partial discharge inception voltage (PDIV) for each design.

The resulting FE models were analyzed using two techniques: a traditional maximum-field-based approach and a newly-proposed critical-area integration method.
