| Abstract: | For the drawback of the power regulation in the existing current fed CPT system, a novel circuit topology and control method is presented, which can realize either Buck or Boost mode and can extend the power regulation scope. The improved topology is modeled, while the relations between the duty cycle and the output power for the two modes are derived for system analysis and design. Simulink and PLECS are used to simulate the PP type CPT system. The simulation results prove the theory analysis. |
