Description

Multi-output semiconductor crown block vehicle-mounted non-contact power supply module Technical Field The utility model relates to the technical field of power electricity and control electricity isolation, in particular to a multi-output semiconductor crown block vehicle-mounted non-contact power supply module. Background The semiconductor crown block system is a carrier for automatically carrying wafers, and is required to operate without faults for 10 years in an electrified state, and if an crown block alarms, the crown block system needs to manually read data reported by a crown block control system at a main control console to analyze the reason of the alarm. If the power is off, the crown block control system needs to perform system self-checking and communication connection for more than 1 minute, so that the whole production line is blocked. The power supply of the overhead travelling crane vehicle-mounted control circuit is required to be always in a live working state and can not be powered off. The servo system of the crown block needs 300V direct current power supply, the control system needs 48V direct current power supply, the non-contact power supply system is unified to the vehicle end module to supply 300V direct current, and one path of 300V direct current is separated in the crown block and is converted into 48V power supply for the control system through a switching power supply. In order to ensure that the control electricity is not powered off, super capacitors are generally added at the 300V output end uniformly to provide energy for the control electricity. This mode is simple to design for a contactless power supply system, but for the whole crown block system: 1. A 300V-to-48V switching power supply is needed to be added in the vehicle body, and the volume and the weight are large; 2. The voltage limit of the super capacitor monomer is only 4V, and the volume and the weight of the super capacitor array to be formed into 300V grades are very large; The 3.300V super capacitor supplies power to the servo motor system and the control system at the same time, the energy distributed to the control system only occupies a small part, and the energy utilization efficiency is low after the switching power supply is converted; 4. Because one power supply system is shared, if the main circuit fails, the control circuit is immediately powered off, so that the whole production line is broken down. The running speed and the acceleration of the crown block system determine the production efficiency and the productivity of the whole production line, and the volume and the weight of the internal module determine the limit speed and the acceleration of the crown block, so that the crown block weight reduction is an important way for improving the production efficiency of a wafer factory by optimizing the volume and the weight of the non-contact power supply system module. Disclosure of utility model The utility model improves the traditional single-path direct current 300V output into 300V and 48V double-path output, realizes the isolation of power electricity and control electricity, and ensures the stable power supply of the crown block system.
