In this paper, we examine the passivity and stability of quasi-static partial element equivalent circuit models. The impact of inaccuracies in the computed partial element values is considered as a possible source of time domain instabilities. Our analysis shows how existing partial element calculation routines, analytical and numerical, and the use of poor mesh generators can introduce large errors in partial element values We also show how this affects the passivity and stability of the PEEC
