The scheme can effectively reduce the capacity of diesel generators, improve fuel consumption efficiency, and reduce the disturbance of the voltage and frequency of the shipboard power system. At the same time, because the bow thruster can operate as a generator when braking, the battery storage can replace the consumption resistance and absorb the energy generated by the fast braking machine. An adaptive PI controller for the voltage loop is designed for three phase interleaved DC/DC converter to stabilize the DC bus voltage, and the selection of controller parameters are analyzed. Simulation results show that the controller can effectively suppress the voltage swell and sag of DC bus during the frequent start-up process of the bow thruster.
