Abstract

This paper presents the analysis of a pulse-width modulated (PWM) quadratic buck or BUCK² converter operating in continuous conduction mode (CCM). This class of converter offers very wide range of DC voltage conversion ratio enabling higher switching frequencies. In this paper, the steady-state analysis of the quadratic buck converter is presented. Results pertaining to the operation of the converter at boundary between continuous and discontinuous modes is discussed. A 24 V/10 V, 9 W quadratic buck converter is considered as a design example. Simulation results obtained using SABER circuit simulator are provided validating the analysis presented in the paper.
