Abstract：Inductive coupled power transmission technology(ICPT)has been widely applied in the pow-er supply system of underwater equipment due to its advantages in reliability and security.To avoid the obvious fluctuation of the output voltage of ICPT system with multi-receivers with the working distance and the secondary quantity changes,we proposed a primary-side control strategy based on the active disturbance rejection controller(ADRC).By capturing the primary-side current as feedback,the strat-egy can maintain a constant voltage output without any communication module or voltage stabilizing module.The hardware circuit and control flow of the power transfer system was designed,respective-ly,by establishing the circuit model of multi-receivers ICPT system.The simulation based on Matlab/Simulink &Maxwell and the experiment of third-receivers ICPT system provided the rationality and validity of the above theory.At the same time,experiment result proved that the control strategy has better robust performance and dynamic characteristics compared with other methods.
