High efficiency step-up converter using single switch with coupled inductors

Due to high demand for voltage boosting in the field of renewable energy sources, a novel topology step-up converter with single switch is proposed this paper. The uses coupled inductors architecture. enables control stepping-up gain by adjusting duty cycle and selecting appropriate turn ratio inductors. two circuit can act as transformer. Moreover, technique aims harness turning off stresses across switching element suppress stress transferring it load. induced was reduced forwarding power charge capacitor then transfer through diode output. Circuit configuration, principles operation function are demonstrated. verified comparing practical results theoretical.
