High Voltage Gain

This paper proposes a high step-up high-efficiency converter, comprised of an active switched coupled-inductor cell. The secondary windings are integrated into a rectifier voltage multiplier cell in a boost-flyback configuration, allowing the operation with high voltage gain with low switches duty cycle and low turn-ratios on the coupled-inductors. Both coupled-inductors are integrated into a single core due to the parallel operation of the switches. The leakage inductances of the coupled-inductors are used to mitigate the reverse recovery currents of the diodes, while regenerative clamp circuits are used to protect the switches from the voltage spikes caused by the leakage inductances. The operation of the converter is analyzed both quantitatively and qualitatively, and the achieved results are validated through experimentation of a 400 W prototype. A 97.1% CEC efficiency is also reported.

Multiplier Circuit

This paper presents a high voltage gain of a DC-DC converter. The proposed system consists of voltage multiplier circuits and a coupled inductor of a boost DC-DC converter. The input voltage of the voltage multiplier circuit is the induced voltage of inductor at a boost DC-DC converter. The field programmable gate array (FGPA) is used for generating the control signal of the proposed system. To verify the proposed circuit, an experiment was conducted from the prototype circuit. The proposed circuit can step-up the voltage with high voltage gain. Moreover, the voltage across the switch is very low.
