Problems solved by technology

[0004] This leads to the problem of switching between the two power supply methods. At present, the transition of OHT from the track to the maintenance room in the industry is done in a non-automatic way, which is achieved by manual handling, which is a waste of manpower.

Abstract

The invention provides a power supply switching system. The power supply switching system comprises a control circuit, a power supply interface, a non-contact power supply module and an AC power supply module. In a first state, the control circuit controls a first capacitor in the non-contact power supply module to discharge electricity to the power supply interface when the non-contact power supply module stops supplying electric power in order to make the power supply interface switch to the AC power supply module for supplying power under an action of electric energy generated by electric discharging. In a second state, the control circuit controls a second capacitor in the AC power supply module to discharge electricity to the power supply interface when the AC power supply module stops supplying electric power in order to make power supply interface switch to the non-contact power supply module for supplying power under an action of electric energy generated by electric discharging. The power supply switching system realizes automatic switching between two different power supply systems, reduces cost, avoids labor of carrying by workers and improves production efficiency.

Description

technical field [0001] The invention relates to the field of power electronics, in particular to a power supply switching system. Background technique [0002] AMHS (Automatic Material Handling System, Automatic Material Handling System) is mainly used in the handling of semiconductor wafers, and OHT (High Altitude Transport) is an important part of AMHS. [0003] During the transportation of OHT on the track, the non-contact power supply or battery on the track is used to provide working power. When the OHT needs maintenance or battery charging, it needs to enter the maintenance room. In order to save costs, the OHT usually uses AC220 uses non-contact power supply to supply power to OHT instead of erecting rails. Therefore, the equipment in the maintenance room is powered by AC220V. [0004] There is a problem of switching between the two power supply methods. At present, the transition of OHT from the track to the maintenance room in the industry is done in a non-automati...
