Abstract
While a new type of power take-off (PTO) based on mechanical-motion-rectifier has been developed, its dynamic model is over simplified and cannot properly predict its nonlinear system characteristics. There is a need to develop a high fidelity PTO model to predict the system dynamics. An equivalent circuit would be a convenient tool to model the system behaviour and can easily apply to a circuit-based wave-to-wire (W2W) model. In this paper, a methodology for deriving a circuit-based high-fidelity model through the PTO design is introduced following by the extraction of the parameters through experimental results. Finally, the PTO circuit model is validated by the bench test results under the time domain
