摘　　要：在野外供电不便的情况下,为了给各类维修工具及电子仪器供电,采用了ATmega8单片机编程控制脉宽调制芯片TL494及开关管专用驱动集成IR2110,逆变产生纯正弦波交流电压,设计得到了一种智能化程度较高的正弦波逆变器。通过实际应用证明,该逆变器具有便于携带、功耗低、性价比高、抗干扰能力强等特点。In the case of power supply in the open where power supply is inconvenient, in order to provide power supply for all kinds of repair tools and electronic equipments, the ATmega8 single chip microcomputer for programming was used to control pulse width modulation chip TL494 and integrated IR2110 for switch pipe driving to produces pure sine wave alternating voltage by inversion. A higher intelligentized sine wave inverter was designed. The actual application proves that the inverter is easy to carry, and has the characteristics of low power consumption, high cost performance and perfect anti-interference capability.
