摘要
车载逆变器将汽车蓄电池的12 V直流电转化为工频220 V交流电,数控正弦波逆变器输出电压特性好,适用于各类小功率车载电器设备。系统采用DC/DC推挽升压和DC/AC全桥逆变两级结构以及基于dsP IC33FJ16GS502单片机的数字控制策略,研制一台150 W正弦波车载逆变器。试验结果表明,样机工作稳定高效,正弦度好,谐波畸变率小,具有良好的应用前景。
Vehicle-mounted inverter converts 12 V DC car battery to 220 V AC power. Digital control sine wave inverter has high quality of output voltage and applies to all types of low-power on-board electrical equipment. The system consists of two stages ,which uses push-pull inverter as the DC/DC topology and full-bridge inverters as the DC/AC topology. A 150 W sine wave vehicle-mounted inverter was developed based on the digital control strategy by dsPIC33FJ16GSS02 MCU. The experimental results show that the prototype is stable and efficient, of good sine degree, THD is small,which has a good prospect.
