摘要
针对航天器平台一级能源变换高压大功率的应用需求,采用并联式DC/DC变换器的最大功率点跟踪(MPPT)拓扑结构,设计一种顺序开关分流最大功率调节(S^3MPR)电源控制器。为了解决传统S^3MPR技术的算法电路复杂、跟踪精度低等问题,兼顾航天器应用环境的特殊性,通过采用模拟电路实现的方式设计出一种基于交错扰动方法的MPPT控制算法电路。该算法可以实现太阳电池阵电压电流输出较大范围内精确跟踪其最大功率输出。研制了5 kW功率(10路太阳电池阵)的原理样机对设计进行试验验证,结果表明:电源控制器性能良好,满足高压大功率航天器平台的应用需求。
An S^3MPR(sequential switching shunt maximum power regulator) power controller is designed for the demands of the primary energy conversion of high-voltage high-power spacecraft platforms. The controller belongs to the MPPT topology of a parallel DC/DC converter. In order to improve the complex algorithm circuits as well as low tracking accuracy of traditional S^3MPR technology and take the particularity of the spacecraft application environment into consideration, an MPPT control algorithm circuit based on the staggered disturbance method is designed using analog circuits. It can accurately track the maximum power output when the voltage and current output range of the solar array changes widely. A 5 kW power(10-channel solar array) prototype is completed to verify the design. The results show that the power controller performs well and meets the application requirements of high-voltage high-power spacecraft platforms.
