“…In applications that require a step-down of the input voltage, buck-type topologies are the first choice due to their compact size and ability to handle varying loads [ 1 , 2 ]. They are commonly used in various electronic devices and applications where efficient power converters are necessary, like power supplies [ 3 , 4 ], battery charging [ 5 , 6 , 7 , 8 , 9 , 10 , 11 ], IoT applications [ 12 , 13 ], LED drivers [ 14 , 15 , 16 ] and renewable energy [ 17 ].…”

The paper introduces a step-down converter that exhibits a static conversion ratio of cubic nature, providing an output voltage which is much closer to the input voltage, and at the same duty cycle, compared to a wide class of one-transistor buck-type topologies. Although the proposed topology contains many components, its control is still simple, as it employs only one transistor. A dc analysis is performed, the semiconductor stresses are derived in terms of input and output voltages and output power, revealing that the semiconductor voltage stresses remain acceptable and anyway lower than in other cubic buck topology. All detailed design equations are provided. The state-space approach is used to analyze the converter in the presence of conduction losses and a procedure for calculating the individual power dissipation is provided. The feasibility of the proposed cubic buck topology is first validated by computer simulation and finally confirmed by an experimental 12 V–10 W prototype.
