Study and application of soft-switching three-phase inverter in AC drive system based on the DSP
摘要
Abstract
At present,the study of soft-switching inverter technology in AC drive system is quite prevailing,while that on the application of soft-switching technology and DSP (digital singnal processor) technology are comparatively much lagged behind.The dead-time effect is the main characteristics of the three-phase inverter.So in order to improve the reliability of their work and the quality of output current waveform of the inverter,the ADRPI (auxiliary diode resonant pole inverter) is taken as an object to analyze the topology configuration and work principle.Based on these,formation mechanism,size and influencing factors of dead-time are investigated as well as the impact of dead-time effect on soft-switching inverter.Through mathematical model construct,simulation experiments and AC speed regulation based on the DSP,it's demonstrated that the application of the ADRPI soft-switching three-phase inverter and reasonable configuration of dead-time is able to significantly improve that the quality of output current of inverter.These results provide references for further applying ADRPI softswitching inverter in practice.关键词
