Magnetic-coupling-based wireless power transfer systems and schemes are provided that ensure fast wireless power transfer to charge batteries of electric vehicles (EVs) with high power transfer efficiencies and safety to humans and other animals in or near the EVs. A wireless power transfer system can include a direct 3-phase AC/AC converter with a circuit topology that enables bidirectional power flow. The direct 3-phase AC/AC converter can convert a power input at a low frequency, such as 3-phase 50/60 Hz, into a power output at a high frequency, such as a frequency in a range of 10-85 kHz for wireless power transfer applications.
