Design and implementation of energy-saving power supply for electrified-education multimedia equipment
摘要
Abstract
The power supply module is a basic unit of the electrified-education multimedia equipment.In order to reduce the power consumption of the electrified-education multimedia equipment and design the energy-saving power supply,an energy-saving power supply design scheme based on distributed control system (DCS) is proposed.The low-power consumption STM32F101xx chip is taken as the central control unit of the microprocessor.The energy-saving power supply system module includes the power amplification module,driver module,overcurrent and overvoltage protection module,and interface module.The modem MOS technology is used to conduct the overcurrent and overvoltage protection.The digital isolator is set to improve the voltage stabilization performance of the power supply.The DCS is adopted to reduce the radio frequency interference,and realize the optimization design of the energy-saving power supply.The experimental results show that the designed energy-saving power supply of the electrified-education multimedia equipment has high peak-to-peak value of output voltage,low power consumption,strong power supply stability,and good energy-saving effect.关键词
