Abstract

In the article isolated and non-isolated dual inductor-fed DC/DC boost converters were compared. Among various current-fed type boost topologies, a dual inductor-fed boost converter thanks to smaller inductor’s current is the most attractive scheme due to the high voltage conversion cycle, less stress on power switches and lower conduction losses. Unfortunately most of current-fed boost topologies including dual-inductor schemes have crucial defects such as a high voltage spike when a switch is turning of. Also soft start-up is not possible due to the limited range of duty cycle above 0.5. By integrating an isolated dual inductor-fed boost converter and a parallel boost converter, a non-isolated converter has been created, but the mentioned problems were only limited. Topology verification was performed by testing the prototypes of power converters in power range (100–1400) W and input voltages (10–40) V using identical components.
