Zusammenfassung: | This paper presents a transient forward harmonic adjoint sensitivity analysis
(TFHA), which is a combination of a transient forward circuit analysis with a
harmonic balance based adjoint sensitivity analysis. TFHA provides
sensitivities of quantities of interest from time-periodic problems w.r.t. many
design parameters, as used in the design process of power-electronics devices.
The TFHA shows advantages in applications where the harmonic balance based
adjoint sensitivity analysis or finite difference approaches for sensitivity
analysis perform poorly. In contrast to existing methods, the TFHA can be used
in combination with arbitrary forward solvers, i.e. general transient solvers. |
