Özet
To increase the voltage gain of power electronic circuits, numerous converters have been designed by researchers. In particular, step-up converters are used in various circuits and systems due to their reliability. Mostly, in some studies, researchers proposed to use coupled inductors and switched capacitors. Therefore, in this study, we aim to use new-generation E-HEMT switches by using a hybrid topology which includes both a switched capacitor and a coupled inductor to deliver ultra-high voltage to the output. The proposed switched capacitor-based hybrid converter (SCBHC) is modeled in Simulink and PowerSim to verify the analytical voltage gain derivations. The proposed SCBHC is compared with a traditional boost converter, a switched capacitor-based topology and two different coupled inductor-based schemes in terms of gain performance for different duty cycles, switching frequencies and turn ratios. With this combined design, we obtain approximately 300-400% more voltage gain than a traditional boost converter. The proposed SCBHC provides a considerable gain and a wide output voltage range with lower turn ratios compared with other topologies.
