The InQor Half-brick converter series is composed of next-
generation, board-mountable, fixed switching frequency dc-
dc converters that use synchronous rectification to achieve
extremely high power conversion efficiency. Each module
is supplied completely encased to provide protection
from the harsh environments seen in many industrial and
transportation applications.
