Analysis and Design on Disturbance Depression in EPC Used in Spaceborne TWTA
-
摘要: 氣象衛(wèi)星星載行波管放大器TWTA的抗干擾能力是其可靠性的一個(gè)重要參數(shù)。為空間行波管TWT提供電源及控制的EPC的抗干擾性對(duì)整個(gè)TWTA的抗干擾能力起主要影響。該文以EPC中預(yù)穩(wěn)電路為例,利用開關(guān)電源的小信號(hào)模型分析了電路對(duì)穩(wěn)態(tài)干擾的響應(yīng)、運(yùn)用PSPICE進(jìn)行瞬態(tài)干擾分析,給出了PID(Proportional-Integral-Differential)參數(shù)最優(yōu)設(shè)計(jì)方法,實(shí)際結(jié)果滿足要求。

Abstract: Disturbance depression is very important to the reliability of spaceborne TWTA and the Electronic Power Controller (EPC) is responsible for the disturbance depression of it. In this paper, based on small signal model and PSPICE, the responses to static and transit disturbance in the pre-regulation stage of EPC are analyzed. And the design for PID is given, the results are satisfactory. -
