| description | A multi-stage active switched inductor-capacitor network (SLCN)-based high gain DC-DC converter structure with a single switch is proposed in this paper. The idea of utilizing multiple number of SLCN networks to achieve an ultra-voltage gain is proposed. The achievement of ultra-gain helps to operate the converter at lower duty ratio. Hence, a reduction of conduction loss, improvement in efficiency and elimination of core saturation are attained in the proposed bi-quadratic converter compared to the conventional converters. The performance of a biquadratic boost converter which is formulated from the <inline-formula> <tex-math notation="LaTeX">$n$ </tex-math></inline-formula>-stage SLCN converter for <inline-formula> <tex-math notation="LaTeX">$n=2$ </tex-math></inline-formula>, is analyzed. To reduce the effect of parasitic elements of the semiconductor devices, the SiC-based devices are selected. The small-signal model of the biquadratic converter is derived, and a PI controller is designed to regulate the output voltage. The designed controller is implemented using XSG platform. Experimental waveforms for 650 V output voltage, 500 W output power and 50 kHz switching frequency are presented. The performance of the proposed converter with similar recently reported topologies is compared. Simulation results of the bi-quadratic converter interfaced solar PV panel with P&O algorithm are presented to assess the feasibility of the proposed converter in solar PV application. |
