Work & Capacitance

  1. Sep 23, 2014 #1
    Hi there,

    I have a system that trace every 10ms the voltage of the dc link and in parallel there are capacitors on the DC Link that is about 100 F. The DC Link Voltage can raise as high as 300VDC and it fluctuates.
    (I am just throwing out numbers as I'm just trying to grasp the concepts)

    To find the energy of the system I used 1/2 CV2
    From the table here that I calculated. Would it be right to say :
    Energy At that Instant would be 1/2 CV2
    Energy Consumed would be the positive value, and the negative values would mean there is excessive energy is returned back to the dc link?

    Hope someone could clarify this. Thanks!

    Hi AmazingTrans. I see you are new here. http://img96.imageshack.us/img96/5725/red5e5etimes5e5e45e5e25.gif [Broken]

    That is the energy stored in the capacitance, from sample to sample.
