A novel combined inductive power transfer (IPT) and capacitive power transfer (CPT) for dynamic charging of electric vehicles is proposed to reduce power pulsation. The capacitive couplers, which are aluminum plates, are placed between the inductive coils. Both IPT and CPT systems are operating simultaneously and contribute to generating the overall output power. The distance between IPT and CPT couplers is selected in a way that they do not have an impact on each other's performance. By using this proposed combined system, the power pulsation is reduced and limited to ±6%. The reduction in power pulsation is achieved due to the operation of the CPT system to nullify the zero output power of the IPT system when the receiver is between the inductive coils. The proposed system is cost-efficient as the aluminum plates are used instead of additional coppers which are more economical. An LCC-Compensated IPT system is connected with an LCLC-Compensated CPT system. First order harmonics approximation (FHA) method is used to analyze the circuit performance.
