Kurzbeschreibung (Abstract)
This thesis introduces multiple new approaches to efficiently perform adjoint sensitivity analyses for large scale time periodic electric circuits. Firstly, transient forward harmonic adjoint sensitivity analysis combines an efficient transient simulation with a harmonic solution of the adjoint system. Secondly, Parareal adjoint sensitivity analysis sticks to transient simulation for both the forward and the adjoint problem but accelerates those with the Parareal algorithm. Thirdly, the periodic adjoint sensitivity analysis uses a periodic solver, such as periodic Parareal with periodic coarse solver, to efficiently calculate the periodic solution only and uses the solution in a modified adjoint integral. All proposed methods are applied to several application examples, including real world circuit applications with a large number of electrical devices. Most notably, these circuits include a DC-DC converter, a B6 bridge-motor supply circuit and an active filter.
