Abstract

The design of power converter circuits is highly dependent on the types of the input and output terminations. Conventional dc-dc converters assume the input termination being a voltage source, and the converter circuits so developed are voltage-source-mode (VSM) converters which generally consist in switching an inductor between the input and the output with two complementary switches. However, when dealing with an input current source, the counterpart current-source-mode (CSM) converters are much less known. This article derives all single-input dual-output (SIDO) converters that inherently achieves no cross regulation using both VSM and CSM buck and boost converters, and provides a detailed comparison of the different SIDO configurations in terms of step-up and step-down functions, connection type, number of ground-referenced drivers, number of inductors, number of capacitors, voltage stress, and current stress. The control requirements for independent regulation of the two outputs are discussed. For illustration purposes, one specific CSM SIDO converter is presented and its detailed operation and design considerations are discussed. Finally, experimental results are presented to verify the analytical findings.
