A New Highly Step-Down Quadratic Converter

This paper introduces a hybrid step-down converter of quadratic nature which is derived from a quadratic Buck-Boost-type converter. The new topology is well suited for applications that require a higher step-down voltage difference between the input and output. For the obtained converter, a DC analysis was carried-out. In order to check the validity of the theory developed and analysis, simulations were carried out using CASPOC software. Subsequently, practical experiments were performed, resulting in a remarkable agreement between the observed outcomes and the theoretical predictions.
