Wireless power transfer (WPT) is more convenient and safer system to transfer the power from one end of system to another end system with coil having high inductance value. Wireless power transfer systems is employ to charge the battery pack of electric vehicles (EB) than conventional plug-in system. A wireless method of charging is suitable for charging massive electric vehicle by having multilevel inverter across input side of the system. In this paper we used the 5 level cascaded H bridge multilevel inverter. The multilevel inverter is employed to synthesis of several levels of dc voltages. The H bridge multilevel inverter can operate at both fundamental switching frequencies (SF) that are higher switching frequency and lower switching frequency. Even a switching frequency is low system will have lower switching loss and higher efficiency is achieved. The 5 level H bridge multilevel inverter can reduce torque and flux ripples. The using of H bridge multilevel inverter which helps in receiver side to have desired battery without any changes in its terminal voltage irrespective of its frequency by applying H bridge multi-level across the transmitter side battery gets charged.
