Abstract: The present disclosure discloses a control circuit and a control method for a multiphase power supply and the multiphase power supply. The control circuit includes a current reference signal generator and a controller. The current reference signal generator is configured to adjust a first compensation signal according to a first scaling factor and a first voltage signal, so that the first compensation signal follows the first voltage signal in a steady state, and a current reference signal is obtained according to the first compensation signal and the first voltage signal. The controller is configured to obtain a control signal for each phase power conversion circuit according to the current reference signal to control each phase power conversion circuit to provide a power output to a load. The present disclosure can improve a phase-conversion stability of the multiphase power supply, and can achieve fast and accurate control of the multiphase power supply.

Abstract: The present disclosure relates to a switching power supply, and a control circuit and a control method of the switching power supply. The switching power supply comprises N-phase power conversion circuits, N being an integer greater than or equal to 1. The control circuit comprises a current reference signal generating means and a control means. The current reference signal generating means is configured to obtain an integration signal by integrating an error between a first compensation signal and a first voltage signal, and obtains a current reference signal by adding the integration signal and the first compensation signal. The control means provides control signals for respective ones of the N-phase power conversion circuits in accordance with the current reference signal. The first compensation signal represents a difference information between an output feedback signal of the switching power supply and a predetermined reference voltage.

Abstract: A method for controlling a wind turbine connected to an electrical grid includes receiving, via a controller, a state estimate of the wind turbine. The method also includes determining, via the controller, a current condition of the wind turbine using, at least, the state estimate, the current condition defining a set of condition parameters of the wind turbine.
