The wireless power transfer systems using the Class E push-pull inverter for industrial robots

By decrease of the working population, maintenance-saving is becoming important task. We suggest the feeding system for industrial robots by using the wireless power transfer system for decreasing battery maintenance. In this Report, we try to develop the Class E push-pull inverter for feeding a large AGV (Automated Guided Vehicles : transfer robot) at 300-600W. To countermeasure for the efficiency decreased by increasing output power, our circuit uses the compensation capacitor. We got 80% of efficiency at 600W.
