【摘要】 本文在分析了死区效应基础上,根据功率模块相关参数随电流变化导致输出电压损失不同,因而提出了一种新颖的死区补偿时间离线测量方法,并在该方法基础上,根据输出电流大小进行分段补偿。实验结果证明该方法是有效的和可行的。更多还原

【Abstract】 Based on the analysis of dead-time effect, and relevant parameters of power module vary as different currents so as to cause different loss of output voltage, therefore, a novel off-line measuring method for dead-time compensation is proposed and in terms of the method according to different magnitude of output current, different compensation time is used= Experimental results verify the method is valid and feasible.更多还原
