The inverter accepts 60 Hz 3-phase 380 or 440 voltage from the grid to generate 20 kHz of AC electricity into the cables.

The cables create a 20 kHz magnetic field that sends flux through the slim ferrite cores to the pick-ups on the OLEV.

[13][14][15][16] For the Generation 1 OLEV, if the primary and secondary coils are vertically misaligned by a distance over 3mm, the power efficiency drops greatly.

In Generation 2 OLEV, the current in the primary coil was doubled to create a stronger magnetic field that allows for a larger air gap.

The secondary coil uses a thicker variation of the W-shaped cores as a way to make up for the lesser area for the magnetic flux to flow through compared to gen 2.
