Abstract: An inductive power transfer system for a device such as battery charger on an electric vehicle includes a primary circuit having a rectifier and an H bridge inverter connected in parallel with a reactor connected in series to deliver direct current voltage to a stationary primary coil of a transformer. The system further includes a secondary circuit on the vehicle including a secondary coil and another rectifier connected in series. AC voltage from a power supply is converted to DC voltage and then transformed into a pulse width modulated high frequency square wave voltage for electromagnetic transfer from the primary coil to the secondary coil. The square wave voltage is converted back to DC voltage for delivery to a vehicle charger.
