Systems and methods are provided for combined inductive power transfer (IPT) and capacitive power transfer (CPT) to reduce power pulsation in dynamic charging of electric vehicles. Aluminum plates provided between transmitter coils inhibit output power drop, the power pulsation can be reduced, and a constant power profile is provided by operation of CPT system when the receiver is between the IPT coils. As the aluminum plates cover the space between coils, the IPT coils can be separated away from each other by a longer distance compared to conventional segmented coils; therefore, a lesser copper can be used which enhances the cost effectiveness of the provided system. As the respective IPT and CPT system are used alternatively, thus the system's output power can be constant, nearly constant, or effectively constant.
