Appendix I: Glossary of Terms
AC Inverter
A subassembly of the MT-30 on the left side of the cabinet. Converts
AC to DC to regulate the Intermediate DC Bus.
Battery Cycler
A term for the MT-30 that refers to its use in battery charge and
discharge cycling.
Configuration
The wiring arrangement used for a particular load or loads. Also the
selection on the DC Converter front panel that matches the physical
load connections.
Control Mode
The DC Converter's control algorithm, i.e., the parameter being
controlled. Voltage Mode, Current Mode and Power Mode are the
three control modes in which power transfer can occur. Standby Mode
is a fourth mode in which the output terminals are internally
disconnected and no power transfer occurs.
Converter A
(Also Side A) The master or left converter in the DC Converter (high
current).
Converter B
(Also Side B) The slave or right converter in the DC Converter (low
current).
DC Converter
A subassembly of the MT-30 on the right side of the cabinet. Consists
of two independently controllable converters (A and B), each
regulating the output (load) terminals based on front panel settings or
commands from a remote operation system.
Echo Monitor
On MT-30 is used only as an additional RS 232 output to connect to
additional peripherals.
Independent
One of two load configurations (see also Parallel). Two loads may be
controlled independently by converter A and converter B. Each load is
attached from the positive terminal of a converter to the negative
terminal of the same converter.
Intermediate DC Bus
An internal DC Bus between the AC Inverter and the DC Converter.
This bus is not accessible to the user.
Limits
See
Operating Limits.
Load
A device or system connected to the MT-30 for the purpose of
receiving and/or delivering DC power.
Local Operation
Control of the DC Converter is achieved from the front panel.
Mode
See
Control Mode.
Operating Limits
The maximum and minimum operating points for the DC output.
Upper limits and lower limits may be set on Voltage, Current and
Power.
Operating Space
The area enclosed by operating limits on the DC Converter, as plotted
on a graph of voltage versus current.
Parallel
One of two load configurations (see also Independent). One load is
attached to the paralleled positive and negative terminals of converters
A and B.
Remote Operation
Control of the DC Converter is achieved from a remote operation
system via the Remote Operation Interface.
Remote Operation
Interface
The interface between the MT-30 and a remote operation system. The
physical interface is located on the rear of the AC Inverter. The
interface also specifies message structure and contents of messages
exchanged between the MT-30 and the Remote Operation System.
