摘要
高压大功率及模块化安装的卫星功率平台,采用S4R(Sequential Series Shunt Switch Regulator)功率调节技术。针对提高高压大功率空间EPS的效率及动态响应,采用非线性重叠调用和2阶噪声整形调制技术,解决了基于S4R型功率EPS单纯增加输出滤波电容来提高平台动态性能及效率问题。仿真及实验结果表明了该方法的有效性。
The future satellite EPS(Electrical Power Subsystem) requires high-voltage high-power and modular installation.A power regulation technique named S4R(Sequential Series Shunt Switch Regulator) is used in the high power modular platform.Aimed at improving efficiency and dynamic response of the high-voltage and high-power EPS,a low-frequency noise shaping technique is used to nest each module of S4R.Its experiments have proven that this kind of method has a high power conditioning efficiency and high dynamic response performance without a larger capacitor array.
