Abstract: According to the requirement of spacecraft system for secondary power supply, a DC/DC converter circuit structure based on the feedback control of magnetic isolation bidirectional transmission is proposed for the aerospace high-power multifunctional DC/DC converter. Based on this circuit, the auxiliary functions such as over-current protection, forbidding and current sharing are developed. Through the actual test and verification, the product adopting this scheme has excellent performance indicators and good auxiliary functions.
Key words : feedback control of magnetic isolation bidirectional transmission;over-current protection;current sharing;DC/DC converter

隨著國內航天器系統性能的不斷提升,整機單位對于高可靠、多功能、小體積的厚膜大功率DC/DC變換器的需求也越來越多。單機設計者為減少體積、簡化設計、提高可靠性,往往希望所用的DC/DC變換器能夠具有自我保護、遠程遙控、多塊產品并聯等能力[1]。在空間站、載人航天、商業衛星等航天領域中,許多用戶提出了66 W~120 W大功率輸出,具有過流保護、禁止、并聯均流等輔助功能的抗輻照DC/DC變換器研發需求。目前,此類DC/DC變換器的來源主要依賴進口,如美國Interpoint 公司的MOR系列DC/DC變換器。因此開發國產大功率多功能DC/DC變換器十分必要。
