On the Efficiency of DC to DC Converters Based on Switched Capacitor Networks |
| |
| Abstract: | A study on the efficiency of DC to DC converters using switched capacitor networks is made.A formula applicable to any types of switched capacitor converters is derived.A new topology is proposed,which is capable of improving the efficiency of buck and boost switched capacitor converters. Results from both experiment and computer simulation are in good agreement with those from theoretical analysis. |
