Description
The CPA and CPD Series are highly reliable power supplies
for CompactPCI
®
systems, which are increasingly used in
communications, industrial, military, aerospace, and other
applications. These power supplies offer high power density
in plug-in modules that meet the requirements of the PICMG
®
power interface specification for CompactPCI
®
systems.
The converters use the patented EDGE
TM
technology and
provide important advantages such as flexible output power,
extremely high efficiency, excellent reliability, full input-to-
output isolation, negligible inrush current, hot-swap
capability, soft start, and overtemperature protection.
The input is protected by a transient suppressor (varistor)
against surges and transients occurring on the source lines
and cover an operating input voltage range from either 90 to
264 VAC or 36 to 75 VDC.
The outputs are protected against continuous overload,
open-circuit, and short-circuit. Full n+1 redundant operating
mode is made possible by integrated ORing FETs or ORing
diodes. When several converters are connected in parallel, a

AC-DC and DC-DC Converters
single-wire connection between converters ensures proper
current sharing.
The converters are designed with two or three separate
forward converters with fixed switching frequency and
synchronous rectifiers at their output.
LEDs on the front panel and various warning signals display
the status of the converter. The aluminum case acts as a heat
sink and as an RFI shield. It is designed for vertical insertion
into 19" rack systems, but it can also be mounted in any other
position, as long as the necessary airflow is ensured. The
connector is a 47 pin type from Positronic or similar.
Several options are available to meet different requirements.

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.
1
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

All models have a separate auxiliary supply for the primary

secondary bias voltage of the other models is generated by
the forward converters. Only the forward converters are
controlled by the inhibit and enable inputs; see
Auxiliary
Functions.

leading and trailing-edge pulse-width modulation. It has a
proven track record in high-availability power solutions.
The switching frequency is typically 135 kHz. Some models
(CPx200/250 version V117, CPA500/550 version V110) exhibit
a crystal oscillator with 131 kHz.
