2.8 Signal waveforms cont.

Example 2-2 cont.

EAC = Energy for AC case = Pave. ´ TAC = [(VRMS)2/RH] ´ 5 Min. \ EAC = [(170 V./Ö2)2/RH] ´ 5 Min.

EDC = Energy for DC case = PDC ´ TDC = [(VDC)2/RH] ´ TDC \ EDC = [(48 V.)2/RH] ´ TDC

Then: EAC = [(170 V./Ö2)2/RH] ´ 5 Min. = [(48 V.)2/RH] ´ TDC = EDC which yields TDC » 31 Min.
