基于高频整流模式新型EPS及工作原理分析

A New-type EPS Based High-frequency Commute Pattern and Analyze the Principle

EPS作为一种可靠的绿色应急供电电源,在电梯、消防、应急照明等场合发挥重要作用。根据PWM整流器能量双向传输的特点,发展新型EPS应急电源在消防电源中的应用,其充电、放电都由PWM整流器完成。新型EPS应急电源优化传统EPS电源的结构和控制策略,提高消防电源的效率和管理信息化程度。对新型EPS应急电源的工作原理进行深入的分析,针对直接电流双环PID控制策略在MATLAB环境下进行仿真研究,并对仿真结果进行扼要的分析。

As a kind of reliable and green - line emergency power supply, EPS acts more important effect in the field of elevator, fire protection, emergency illumination, Base on the power bidirectional transfers by PWM rectifier, advance a new type EPS emergency power supply for fire protection, of which charging and discharging finished by one PWM rectifier. The new type EPS optimize the configuration and the control of the traditional one and advance efficiency and the degree of manage information. Analyzes the principle of the new - type emergency power supply profoundly, and simulation studies the direct current - double loop PID control by MATLAB, and analyzes the result of MATLAB simulation.
