SY3634

Product Overview
SY3634
Bipolar Power Supply Heterogeneous System
High efficiency, low cost, high stability, easiness of configuration and maintenance are the key
features of this new power supply (PS) system.
Especially designed to operate in particle accelerator facilities, i.e. Synchrotrons and FELs.
The system houses up to 4 independent current-controlled bipolar power supply modules.
Different combinations of up to 4 modules (chosen among 5A, 10A, 20A or 30A) can be easily
installed in the same rack.
Extremely versatile and easy to “tune” to any load/magnet condition.
Features
t Digital feedback current control loop
t Graphic color display OLED and an
encoder per channel for local control
t Up to 95% DC/DC power conversion
efficiency
t True bipolar zero-crossing operation
t Ethernet connectivity
t 8 (eight) independent external
interlocks user-selectable
t On-module speed-regulated fans
t Internal temperature monitor circuits
t MS Windows, Linux and MAC OS
t Epics- and Tango-compatible
High efficiency, low cost, high
stability, easiness of configuration
and maintenance are the key features
of this new power supply (PS) system,
especially designed to operate in
particle accelerator facilities like
Synchrotrons and FELs.
The system houses up to 4
independent current-controlled
bipolar power supply modules,
ranging from 5A to 30A, in a single
19-inch 3U standard crate (SY3634).
Different combinations of modules
(chosen among a catalogue including
5A, 10A, 20A or 30A channels) can
easily be installed in the same rack.
Applications
t Magnet Power Supplies
t Current Waveform Generation
t Accelerator Machine Power Supplies
t Beamline Magnetic Experiments
t Nuclear Magnetic Resonance (NMR)
An auxiliary AC/DC converter
module, the A3636 - SY3634,
powers the control circuits. Each
module implements a completely
digital feedback control loop with
a proprietary PWM generation
technique: this makes the system
extremely versatile and easy to “tune”
to any load/magnet condition.
Modules are composed by a Control
Board (CB) and a Power Board (PB)
that are mechanically connected:
communication between boards
is almost exclusively performed by
digital signals that avoid possible
analog signal corruption and
undesired noise pick-up.
The CB is mainly composed by a DSP
that performs current control and an
FPGA that supervises all processes
like communications, diagnostic
operations and interlocks handling.
Remote communication is
guaranteed by means of an Ethernet
10/100 auto-sensing socket present
on each module front panel. The
PS can also be locally monitored/
controlled via an encoder and a
graphic color display featuring userfriendly menus.
An external DC bulk power supply
feeds the PB power section and its
ancillary parts. Cooling is performed
by embedded fans, directly
controlled by an output currentrelated hysteretic algorithm.
Software and drivers are available for
different operating systems like MS
Windows, Linux and Mac OS; these
devices are also Epics- and Tangocompatible.
