一、前言为了配合野战光纤通信网光端机的研制,我们承担了该机的电源研制任务。为了战时使用方便,该机对电源的要求是可靠性要高、体积小且能交流、直流两用。为此,必须研究工作可靠、体积小、效率高、交直流两用的新型电源技术。显然,老式的线性稳压电源技术已不能充分满足以上要求。 I. Preface In order to cooperate with the development of optical fiber communication network in the field, we have assumed the task of power development of the aircraft. In order to wartime convenience, the machine is the reliability of the high power requirements, small size and can exchange, DC dual-use. To this end, we must study the work of reliable, small size, high efficiency, AC-DC dual-use of new power technology. Obviously, the old linear power supply technology can not fully meet the above requirements.
