چکیده :

This study introduces an ultra-high-voltage gain DC-DC converter with dual output ports, featuring a quadratic-based structure tailored for renewable energy applications. The proposed design incorporates a coupled inductor (CI) combined with a quadratic boost stage to achieve substantial voltage elevation. Voltage gain is adjustable through two main parameters: the duty cycle of the power switches and the turn ratio of the dual-winding CI, enhancing design flexibility. Notable characteristics of this converter include its high voltage gain, reduced voltage stress on switching elements, continuous input current, common ground connection between input and output, and synchronized operation of switch. The advantages of this configuration are underscored by comparative analysis with similar topologies. The converter's effectiveness is demonstrated through tests on a 480W prototype operating at a 47 kHz switching frequency, with a 20V input and equal output voltages of 240V.
