Overview of Current-fed Power Processing >>
Innovative
Magna-Power Electronics MT Series combines the best of dc power processing
with multiprocessor embedded control. A combination of high and medium frequency
power processing technologies improves response, shrinks package size, and
reduces cost. MT Series power supplies are current fed and are more tolerant
to abusive loads than conventional switching power supplies.
Scalable Power
MT Series power supplies offer both master/slave parallel and series operation.
This enables two or more power supplies to be placed in parallel for increased
output current or in series for increased output voltage. With master/slave
operation, power supplies operate at near equal voltage and current.
Unparalelled Control
MT Series power supplies can be configured through the front panel for
different applications. The power supply can be programmed to have its control
functions accessible from the front panel, rear connector, or through RS-232,
optional GPIB, or optional LXI-C/Ethernet communications. Sensing can be established
at the output terminal of the power supply or through a rear terminal block
for sensing at the load. An external interlock can be set to enable operation
only when an external connection is made. Even calibration has been simplified
with front panel access to calibration digital potentiometers. MT Series power
supplies incorporate an optically isolated feedback system. The result is that
all user interface circuitry is referenced to earth ground -- not the negative
terminal of the power supply. This enables users to connect external circuitry
without concern of ground loops or voltage breakdown.
Designed for Safety
MT Series power supplies have extensive diagnostic functions -- all of
which, when activated, take command to shut down the system. Diagnostic functions
include phase loss, excessive thermal conditions, over voltage trip, over current
trip, fuse clearing, and program line. Program line monitors externally applied
analog set point signals to insure they are within the specified range. Upon
a diagnostic fault condition, main power is disconnected and the diagnostic
condition is latched into memory. Pressing the clear key clears the memory.
All diagnostic functions can be monitored through a rear connector. Furthermore,
control functions can also be set through the rear connector to allow simultaneous
control of one or more MT Series units. MT Series supplies have three levels
of over voltage/current protection: shutdown of controlling insulated gate
bipolar transistors (IGBT’s), disconnect of main power, and input fuses.
After an over voltage/current trip condition, the supply must be reset.
MTA Version Front Panel
MTA models provide stepless analog control from front panel knobs. With
a simple configuration change, the power supply can be programmed from the
rear I/O connector or through software on one of the communication buses.
MTD Version Front Panel
MTD models provide all of the features of the MTA Version plus these models
can be configured for keypad entries and up/down presses for voltage, current,
over voltage trip, and over current trip. Key strokes are kept to a minimum
by a repeat last command feature. MSD Series power supplies are well suited
for laboratory applications requiring enhanced control.
MTD Series models have one-hundred memory states available to program voltage,
current, over voltage trip, over current trip, and time period. Set points
can be auto sequenced with time or external triggering. Special programming
codes allow repeating to create a power function generator. The first 10 memory
states are displayed on the front panel to simplify programming tasks. MTD
Series power supplies offer an analog input to modulate the voltage or current
setting using piecewise linear approximation. This feature enables the voltage
or current setting to be adjusted by a sensor input, such as a thermistor,
or by monitoring its own voltage or current. Modulation allows the output to
be tailored for advanced process control applications, battery charging, and
source emulation.
MTC Version Front Panel
MTC models hava a blank front panel and only allows control from the rear
I/O connector or by RS-232/GPIB/USB/Ethernet communications. These models are
intended for process control applications where front panel controls and displays
are not required nor desired.
 Remote
Interface SoftwareThe Remote Interface Software is shipped with all MT Series power supplies. The software provides the user with a quick method to operate a Magna-Power Electronics' power supply under computer control. The Remote Interface Software has six windows: the Virtual Control Panel, Command Panel, Register Panel, Calibration Panel, Firmware Panel, and Modulation Panel. The Virtual Control Panel emulates the front panel of the MT Series power supply, the Command panel programs and reads SCPI commands with user friendly buttons, the Register Panel programs and reads registers, the Calibration Panel enables calibration of the digital potentiometers, the Firmware Panel enables the program stored internal to the power supply to be upgraded, and the Modulation Panel eases programming of modulation parameters. |
