Step-up DC-DC converters are essential components used in a wide range of applications. Many researchers have proposed various methods to achieve high voltage gain in DC-DC converters. However, this typically involves adding multiple passive components, which increases system complexity and complicates output voltage control. Maintaining a constant output voltage at the desired value is critical in these converters despite the load, supply voltage changes, and circuit disturbance. Recently, a snubber-less high-step-up enhanced super-lift converter has been developed as a possible solution to these issues. This converter offers high gain without high voltage stress or snubber losses. A model of the converter was created using the state-space averaging technique and is presented in this paper. The control strategy proposed uses the input current in the inner loop and the output voltage in the outer loop. The paper also includes simulation and experimental results that validate the circuit analysis equations.
