| 中文摘要: |
| 介绍了一种采用单片机控制的航空测试用DC/AC逆变电源.直流降压部分采用电流控制型集成芯片UC3846控制,能够显著地抑制推挽变压器的磁偏,并提高负载的动态响应速度.逆变部分的SPWM控制脉冲波形由P87LPC768型单片机生成,精确度高.该航空测试用交流逆变电源具有结构简单、体积小、输出稳定和易于调整等特点.文章最后给出了测试波形. |
| 英文摘要: |
| In this paper,an aeronautic tested DC/AC inverter based on a Micro-computer Unit(MCU) is introduced.The DC/DC boost unit is push-pull circuit controlled by UC3846,which can restrain the magnetic bais of the push-pull transformer and enhance the dynamic load response. The SPWM control pulses are produced by P87LPC768.This inverter has the merits of simple structure,small volume,high output-stablity and easy to be adjusted.The test waveform is present at the end of this paper. |
