小功率车载逆变器研究

A Research on Small Power Vehicle Mounted Inverter

以车载逆变电源为研究对象,对小功率车载逆变器进行整体方案设计,并对逆变器功率电路进行研究,为保证逆变输出端交流电压具有较好的正弦度,对逆变输出端串联的LC滤波器的参数设计和电感设计进行重点论述,最后给出了实验结果及波形分析.实验表明该小功率车载逆变器具有较好的稳态性能.

The overall design scheme of the full- bridge inverter is designed based on the vehicle in- verter power supply. The power circuit of the inverter is studied, and in order to ensure the AC voltage at the output terminals of the inverter has good sine wave, parameter design of the LC filter of the in- verter is discussed, as well as the inductor design. Finally, the paper gives the experimental results and waveform analysis, and the experimental results show that the small power vehicle inverter has good dy- namic and steady performance.
