The VAHLE vPOWER non-contact power supply is intended for automated guided vehicles. The primary coil is a long conductor loop; the secondary coil is placed on an open ferromagnetic core and mounted as a module on the mobile unit. The primary inverter unit converts the 3-phase AC voltage into a single-phase AC with a frequency of 140kHz, while supplying the primary conductor with a constant current. The power modules provide 10kW each and can be cascaded up to 40kW per power feed segment.
