The invention provides an ICPT system and an electric vehicle non-contact power supply system, and relates to the technical field of electric vehicle charging. The ICPT system comprises a wide voltage gain inverter and an energy transmitting and receiving circuit, and the wide voltage gain inverter comprises a first switching device, a second switching device, a first inductor, a second inductor, a first fly-wheel diode, a second fly-wheel diode, a first direct-current capacitor and a second direct-current capacitor. The energy transmitting and receiving circuit comprises a transmitting coil, a receiving coil, a first resonance compensation capacitor and a second resonance compensation capacitor, the transmitting coil and the receiving coil resonate, and the receiving coil is connected with a load through the second resonance compensation capacitor. According to the technical scheme, wide-range adjustment of the output power of the system can be achieved through the two controllable power switching devices.
