SY3634 Heterogeneous Bipolar Power Supply System
The system houses up to 4 independent current-controlled bipolar power supply modules, ranging from 5A to 30A, in a single 19″ – 3U standard crate
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.
An auxiliary AC/DC converter module, the A3636, 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.
