Tolerance Computation of a Power Electronic Circuit by Higher Order Sensitivity Analysis Method
Toshihiro Fukuyama, Toshiji Kato · IEEJ Transactions on Industry Applications · 2001
There is a tolerance between a designed and an actual characteristics when there are circuit parameter variations in a designed circuit. It is necessary to develop a tolerance analysis method which computes the tolerance region under circuit parameter variations. Interval mathematics is one of these analysis methods. However no practical method has been reported for transient or steady-state analysis because they are initial value or boundary value problems. This paper proposes an alternative method which efficiently computes a tolerance region with a parameter polynomial approximately and practically by using the Taylor series expansion with a higher order sensitivity analysis method.
