Max Power
The InQor^® quarter-brick converter series is composed of
next-generation, board-mountable, isolated, 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.
