Switched periodic networks are widely used in power engineering and sensitivities of their steady‐state to element changes are of interest to the designers. The paper develops a method to obtain steady‐state sensitivities for networks in which semiconductor and other switching devices are modelled as ideal short circuits without additional elements. Such modelling has the advantage that switching transients need not be calculated and correct initial conditions after switching are obtained with only four integration steps. It is also shown that sensitivities need not be calculated during the process of reaching the steady‐state. Once the steady‐state is available, integration over two additional periods is sufficient to provide time domain steady state sensitivity to the element changes.
