This article presents a novel non-isolated boost converter based on the voltagelift (VL) technique with high voltage gain. In the current study, the operation principles, the steady-state relations in continuous conduction mode (CCM) and discontinuous conduction mode (DCM), the critical inductance calculation, a theoretical analysis of the power losses, and the state-space averaged model (SSA) analysis with effects of parasitic elements are provided. The proposed converter is compared with other recently proposed non-isolated boost converters, which validates the merits of the proposed converter, such as a higher voltage gain and efficiency as well as better electrical stresses on semiconductor devices. Finally, a 100 W laboratory prototype is developed with experiments to validate the proposed converter's given theories and feasibility.

The voltage of the solar system can produce a maximum voltage up to 16 V during daylight, and it is compatible enough with DC-DC boost converter system to charge batteries at any time due to the behavior of the DC-DC boost converter. Researchers' interests in the converters mentioned above involve a wide range of subjects, such as electrical energy conversion, 2 designing rotary systems in various sizes and power scales, 3 design and optimization of energy storage systems, 4 optimized control strategies, 5 and battery chargers. 6 The converters above switching control are accomplished by pulse-width-modulation (PWM), and by employing a control system, the output voltage can be regulated around an operating point. 7 DC-DC converters using the PWM technique are divided into two categories of non-isolated converters, such as boost, buck, boost-buck, SEPIC, and Cuk, and isolated converters, such as fly-back, forward, half-bridge, full-bridge, and push-pull. 8 Isolation is determined by whether the system has a common input and output ground, which is done by employing a high-frequency transformer.
