these curves illustrates the capacitor charging and discharging periods its charging until time 0.037, after that the discharging period will began, as its clear the discharging has more power than charging

its clear the discharging has more power than charging

There is no physical problem with the discharging power being greater than the charging power for a short amount of time. What matters is the total charge being discharged. From your screenshot, it seems that the integral of Pc from 0 to 0.1 is close to 0. So the total charge discharged from 0.037 is equal to the total charge accumulated before 0.037.

thank you @ Nicolas Schmit for your answers, I have another thing to add, that the charging curve is not linear because the capacitor charging form a PV generator, that's the main reason of how it seems like dis power more than ch, put when I change the PV with normal DC source I figured out the reason.

thanks again brother with my greatness :)
