Pulse Regulation Control Technique for Integrated High-Quality Rectifier-Regulators

The Pulse Regulation control scheme is presented and applied to the boost integrated flyback rectifier/energy storage dc/dc (BIFRED) converter as the most popular member of the integrated high-quality rectifier-regulators (IHQRR). In contrast to the conventional control techniques, the principal idea of Pulse Regulation is to regulate the output voltage using a series of high- and low-power pulses generated by the current of the input inductor, which is operating in discontinuous conduction mode (DCM). In this paper, analysis of the BIFRED converter operating in DCM is presented. Fundamentals of Pulse Regulation as well as its stability analysis and the estimation of the output voltage ripple are introduced. Experimental results on a prototype converter are also presented to validate the analytical and simulation results.
