Power Loss in Switched-Capacitor Power Converters: Causes and Analysis
Note that V out is taken as a constant while calculating the output voltage of the converter because (V out2 − V out1) is negligible compared to its nominal value.However, in calculating the redistribution loss, it becomes important. Once C out is charged to V out2, it is then discharged to V out1 by the load current I out over one …
