In this paper, a new structure for a DC‐DC boost converter is proposed. The
presented converter provides a high voltage transfer gain with lower duty cycle.
Low current and low voltage stress on the switch, enlarged area of operating in
continuous conduction mode (CCM), reduced size of the inductors, and the
input filter are the main advantages of the proposed converter. The high voltage transfer gain with low number of elements has made it suitable to implement. Hence, using only one switch has made the control of the proposed
converter easy. Besides, decreased switching losses and higher efficiency are
obtained. The proposed structure is a combination of the Luo converter and
a booster unit, which its analysis is studied in three modes, CCM, boundary
conduction mode (BCM), and discontinuous conduction mode (DCM). Furthermore, in order to validate the analysis and feasibility of the proposed converter, the experimental results are developed on a low power prototype.
