Wireless charging system of electric logistic vehicle AGV

Abstract

The invention discloses a wireless charging system of an electric logistic vehicle AGV, and in particular relates to an electromagnetic resonant type wireless charging system of the electric logistic vehicle AGV. According to the wireless charging system, wired charging is replaced by wireless charging, so that full-automatic unmanned control of the electric logistic vehicle AGV is achieved; the electromagnetic resonant type wireless electric energy transmission method is adopted, thus increasing transmission distance; a transmitting coil and a receiving coil with magnetic conductive structures are adopted, and thereby the transmission efficiency is increased, and the electromagnetic radiation is reduced; a super-capacitor is used for storing energy, so that quick charging of the vehicle when parking at fixed points can be achieved; a single tuned filter, a single phase rectifier and a small capacity high frequency capacitor are adopted, thus achieving the high power factor on the input side of an inverter; single phase inverter full-bridge phase shifting PWM is adopted to control, thus simplifying the circuit structure.

Description

technical field [0001] The invention relates to a wireless energy charging system for an AGV of an electric logistics vehicle, in particular to an electromagnetic resonance wireless energy charging system for an AGV of an electric logistics vehicle.
