摘要：

This paper presents a new high voltage gain step-up DC/DC topology. This topology has formed from the combination of an LCCT impedance network and switched-capacitor cells with only one power switch. This power switch performs shoot-through state and transfers energy between switched-capacitor cells. The power switch must tolerate half of the output voltage value, and the voltage stress can be decreased by engaging more switched-capacitor cells. This converter works in continuous current mode (CCM). Output gain can be increased by appending extra switched-capacitor cells. Both simulations and experiments evaluate the performance of this new converter. Results confirm the proposed topology and show this converter can reach 91% efficiency under the full -load condition.
