便携式船舶通导开关电源的设计

Design of portable switching power supply for ship communication and navigation equipment

随着船舶电气自动化程度的日益提高,各种船用导航通信电子设备的使用也越发频繁。但是由于设备种类复杂,功能不一,每种设备对电力供应的需求并不一致,特别是在紧急情况下,为了使这些设备能正常工作,急需一种便携式的稳定电源来满足这些核心设备的正常工作要求。针对这种情况,本文分析船用通信导航设备的电力供应系统的特点,设计一种能满足其需求的开关电源。此开关电源电压输出稳定,具有良好的抗电磁干扰能力,并且电源的控制电路容易实现,最终满足了舰载通信导航设备的电源要求。

With the increase of the degree of electrical automation,the use of electronic equipment is becoming more and more frequent. However,due to the complexity of the equipment,the different function,the demand for power supply is different,especially in the emergency situation. In order to make these equipments work normally,a portable and stable switching power supply is needed to meet the requirements of these core equipments. In view of this situation,this paper analyzes the characteristics of the power supply system of marine power supply system,designs a kind of switching power supply,which can meet the needs of the power supply.The power supply can achieve stable and efficient energy output. Finally,the power control circuit is easy to implement,and ultimately meet the power requirements of shipboard navigation equipment.
