为了使车载逆变器可以同时为5个电子设备充电,满足人们日常生活多样化的需求,设计了一款5路输出的车载逆变器,该逆变器包括220V输出和5路不同电压输出结构。介绍了车载逆变器的工作方法,研究了KIS-3R33S内部电路基本原理,提出了使用KIS-3R33S模块结合该逆变器进行5路输出的方案。同时,利用saber对电路进行仿真,并搭载了实验模型进行验证,结果表明:电源各项指标达到设计要求,有较强的实用性和可靠性。
In order to enable the car inverter to charge 5 electronic devices at the same time and meet the diversified needs of people’s daily life, a 5-output car inverter is designed. The inverter includes 220V output and 5 different voltage outputs structure. The working principle of the car inverter is introduced, the basic principle of the KIS-3R33S internal circuit is studied, and the scheme of using the KIS-3R33S module and the inverter to output 5 outputs is proposed. At the same time, using saber to simulate the circuit, and carrying the experimental model for verification, the results show that: the power of the indicators meet the design requirements, strong practicality and reliability.
