Objective: Transformer-less DC-DC converter suitable for low-power applications, with a high voltage gain. With fewer elements, this suggested converter may generate a higher gain voltage at a lower duty ratio. Method: A transformer-less quasi-Z-source DC-DC converter with gain is introduced and examined. To boost the load voltage, the topology makes use of both the switched capacitor and active switched-inductor structure based on the quasi-Z-impedance network. The theoretical outcomes and the converter's functionality are verified by the simulation, which is run using the PLECS software program. Findings: The benefits of the conventional Z-source boost converter, including fewer voltage stress, constant input current, and common ground, are still present in the suggested converter. Additionally, at a relative duty ratio of 0.3, the gain is greatly increased by around 10 times. Each power switch's voltage stress is also significantly decreased. A detailed discussion is held on the steady-state operation. Novelty: A novel architecture with higher voltage gain at a decreased duty ratio is presented in this work. The network of inductors and capacitors typically used to raise the dc-dc converter's output voltage. The suggested topology raises the output voltage by using just one switch and switched capacitor and switched inductor network.
