| Abstract: | This paper provides the design project of programmable control electric current drive based on programmable control interface which utilizes ATmega8 as core to control the current drive.The electric current drive adopts Buck converter to achieve input/output power conversion.The feedback loop uses voltage and current double feedback adjustment to control PWM drive circuit,so that the output of Buck converter could be adjusted.According to set value,the programmable control interface controls the current drive to output the matching value in the form of high frequency PWM output.The performance experiments are carried out,and the result shows that the output of programmable control electric current drive has much higher reliability and faster responding,satisfying the design demand. |
