Functional Description
The inputs of all converters are protected against surges and
transients occurring on the source lines. A highly efficient
input filter and an active inrush current limiter ensure a very
low inrush current of short duration. This prevents circuit
breakers and fuses from tripping at switch-on.
All CPA models have an additional bridge rectifier and a boost
converter to provide active power factor correction (PFC)
according to EN 61000-3-2.
The CPx200/250 models (see fig.1a) are equipped with two
independent high efficient 2-switch forward converters,
switching 180° out of phase to minimize the ripple current at
the input.
On the secondary side, two high-current synchronous
rectifiers supply Vo1 (5 V) and Vo2 (3.3 V) with up to 40 A. The
secondary-controlled Vo3 (+12 V) post regulator is supplied
by an additional winding of the 3.3 V main transformer. The
linear regulator for Vo4 (–12 V) is supplied from the output
choke of the Vo3 output. The output filters reduce ripple and
noise to a minimum without compromising the dynamic
response.

Identification of LEDs on the front panel.
The models CPD500 (fig. 1b) and CPA500/550 (fig. 1c) exhibit
a third forward converter for both outputs Vo3 and Vo4. The
outputs Vo1 an Vo2 provide up to 50 and 60 A.
All outputs are fully regulated and protected from the bus by
decoupling FETs or diodes. A current monitor calculates the
output power. As soon as the output power exceeds the
maximum threshold level, the converter starts to reduce the
output power by decreasing the output voltages.
In contrast to the outputs Vo1 (5 V), Vo2 (3.3 V), and Vo3
(+12 V) with active current sharing, output Vo4 ( – 12 V) has a
droop characteristic for passive current sharing.
If for some reason the voltage of any output exceeds the
nominal value significantly, the converter is permanently shut
down. If option L is fitted, this occurs as well, if the max. output
current is exceeded for a predefined time. To reset, the input
voltage must be removed for a short time.
Power-One's Efficient Dual Geometric Edge Technology
(EDGE TM ) facilitates high current density, increases reliability
by reducing component stresses, and decreases the amount
of heat dissipated. The backbone of this patented technology
is an interleaved, multi-channel forward converter utilising a
