The InQor half-brick converter series is composed
of next-generation, board-mountable, isolated
(REINFORCED
INSULATION),
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.
