[问:yq11999 @21cn.com] 智能功率模块的最小供电电压有多高,它在用DSP控制时的灵敏度能否保持不变?
[答:Luca_ Martino] The EDB board is supplied with a nominal voltage of 15V. The flyback power supply is specified for a range of 12V - 18V. The DSP is powered from this input voltage and reads it. When the voltage goes belove 12V the DSP resets itself and the system-shutdown is safe that means the driver goes in protection mode before the DSP is shutted down.  [2002-12-12 10:46:25]

[答:Luca_ Martino] For this low voltage application I would suggest to have a MOSFET power module instead of IGBT power module so actual iNTERO part numbers would not be the best choice.  [2002-12-12 11:17:08]
[答:单词翻译] low voltage application:低压应用  
[问:yue yang_cn] 马达可以用软件通过驱动来控制这确实是非常好的技术。看了简单的介绍知道它是采用电流的监控来实现的,但马达使用的时间长了,同等的电流所提供的转速是会变的,这该怎样解决。我是搞软件开发的,有无样品先体验一下?
