Two Impedance-Network DC-DC Converters Based on Switched-Capacitor Techniques

This paper devises two impedance-network DC-DC converters based on switched-capacitor techniques to realize high voltage gain. Compared to the traditional ones, the proposed ones vary the position of a diode and add only a capacitor and diode to increase the voltage gain. Moreover, the proposed ones have the same voltage stresses of all diodes, capacitors, and switch, which helps to choose components and reduce economic costs. In order to verify their features, their detailed analysis is demonstrated and compared with traditional converters. Finally, simulation results are conducted to validate their effectiveness.
