A vernier hybrid machine has been developed for use as a linear generator in a wave energy converter. Accurate predictions for power capture require testing this machine in a nonsinusoidal manner. A dynamic model capable of predicting the machine's behavior for this kind of mechanical excitation is presented. Simple equivalent circuit models have been found to be unsuitable for these machines and a flux-linkage map approach is instead used. Experimental results are used to verify this approach and the functioning of a unity power factor controller.
