In recent years, Automated Guided Vehicles (AGV) are used more and more widely in industry. For the problem of pollution and the necessary suspension of battery charging, a sectionalized and contactless power supply system for AGVs is designed. Based on the principle of electromagnetic induction, the system uses power electronic devices to rectify, filter, and invert the primary side of the electric power to supply to the AGV on the secondary side of the track. In addition, power supply lines under the ground are divided into subsections in order to reduce energy waste. Simulation results indicate that the sectionalized and contactless power supply system for AGVs woks efficiently, and this system supplies enough power for AGVs. So it is good to popularize and apply the sectionalized and contactless power supply system for AGVs, which can provide enough power energy for AGVs moving and lifting goods with high power transfer efficiency.
