Isolation
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.
