Abstract In order to realize the precise control of output voltage and current inductive power transfer (IPT) battery charging system, wireless communication‐based are generally employed in a lot existing works. However, stability IPT converter will be impaired if communication fails. This paper proposes novel noncommunication‐based strategy with simple switched controlled capacitor design at receiver side system. A series‐inductor–capacitor–capacitor compensation network is selected verify proposed strategy. Without feedback communication, system can reliable constant over full load range fixed switching frequency. At side, introduced reactive convey output‐side information transmitter form impedance angle. angle detected real time, phase shift regulate or Detailed analysis, implementation, hardware realization presented this paper. 250 W experimental prototype built laboratory Constant for application realized through control. Zero minimized achieved, which allows high efficiency operation. Compared work literature, provides benefits reduced cost, higher reliability stability.
