The ReFlex Power TM system is comprised of a Mainframe, a Controller
module, and one or more plug-in power modules. Its architecture is based
on intelligent power modules under control of and in communication with
a Controller module, all integrated through a backplane-based power and
signal distribution network. Optimized for automated applications, the
ReFlex Power
TM
system is operated through a computer interface, and,
therefore, does not utilize manual controls.
Extensive utilization is made of digital technology with FPGA-
implemented digital feedback loops, supervisories, and state controls.
Each power module has a native digital controller that communicates with
the system Controller module and/or with other power modules. A high
degree of user configurability is provided to allow adaptation of
functionality to the requirements of a particular application.
The power modules use high-frequency power conversion for
implementation of the power processing stages to minimize size, weight,
and maximize power density. Their performance has also been optimized
in areas of accuracy, output slew rates, and ripple/noise. Power factor
correction (PFC) is provided to minimize input current harmonics and the
resultant apparent power that is drawn from the input power source.
Ethernet communications, with future extensions of USB, GPIB, CAN-
bus, serve to accommodate popular instrumentation control interface
buses. All setup, programming, measurement, and calibration functions
can be accomplished through the control interface. An embedded Web
server allows interactive remote control over the Internet.
The ReFlex Power
TM
system is housed in a rack-mount compatible
enclosure, with modules plugging in the front of the Mainframe. The
modular design facilitates accessibility to the modules and maintainability
of the system. All internal power/control connections are made through a
backplane interface, requiring no internal hardwiring of the modules. All
user output and control terminations are at the front of the modules, while
the input power connection is at the rear of the Mainframe. Pin/Socket
connectors are provided for fast installation and quick connection to
application cabling.
