Abstract

A hybrid phase modulated converter (HPMC) with current doubler rectification has superior soft switching characteristics, high efficiency, and low EMI as compared to a conventional phase modulated converter. It has essentially three modes of operation; i) Continuous conduction mode (CCM) ii) Continuous conduction mode with reversed inductor currents and iii) Discontinuous conduction mode (DCM). There is never a discontinuity in conduction in the inductors and the definition of DCM is different in itself. In this paper, the various modes are defined, analyzed and design equations derived. The analyses are also verified with a 500W peak current mode controlled prototype model, switched at 100 KHz and the results are presented. The soft switching behavior of the converter in this mode is also studied and is found to be advantageous.
