Title:
ISOLATED BIDIRECTIONAL DC-DC CONVERTER
Document Type and Number:
WIPO Patent Application WO/2017/116070
Kind Code:
A1
Abstract:
The present invention relates to an isolated bidirectional DC-DC converter for enabling highly efficient control by mixedly using different switching schemes according to the type of load in a bidirectional DC-DC converter applied between a DC grid system and a battery. The isolated bidirectional DC-DC converter according to the present invention controls switching of a first switching unit and a second switching unit so as to control the flow of power by changing a bidirectional DC-DC voltage between the DC grid system and the battery, wherein PSM switching control and SPWM switching control are mixedly used according to charge amounts charged to the battery, thereby enabling the efficiency of a system to be improved.
