General Safety notes
This controller (frequency inverter, DC controller) operates
at high voltage to control rotating machinery. The heat sink
operates at elevated temperature. This equipment must be
operated by qualified, skilled personnel conversant with all
applicable safety standards.
Installation
The Demo Board must be placed on an insulating surface
with a suitable cooling fan to control heat sink temperature.
Suitable mating connectors must be used for the GUI and
motor interfaces. Do not make any alterations or soldered
connections to the printed wiring board. Verify that the input
selector switch matches the AC supply voltage.
Protection
A flashing yellow LED indicates that DC bus voltage is
present. Before handling the controller, check that this LED
is not flashing and that the AC input voltage applied to J4
pin1 and pin2 is turned off.
Note: High voltage is present on the motor connections dur-
ing operation.

System Description
The IRAMS10UP60X is a complete 3 phase drive for appli-
ance and other small motor drive applications. It is a power
conversion unit for a 120V, 230V, 3-phase, 350W AC PWM
(Pulse Width Modulated) drive. The system is based on an
8-Bit Micro controller used to generate the PWM informa-
tion and implement the motor control loop. The power stage
is the new IRAMS10UP60A, Advanced Intelligent Power
module (AIPM) developed and optimized for electronic mo-
tor control in appliance applications, such as washing ma-
chines and refrigerators. This 600V power module contains
6 IGBTs with soft recovery commutation diodes, 3 bootstrap
diodes and one 3-phase IC driver. There is also a thermistor
to monitor IGBT temperature and an RC network for auto-
matic fault trip reset.
Figure 1 shows the complete assembly of the
IRAMS10UP60A Reference Design Kit. and Figure 2 illus-
trates a typical connection block diagram.
The printed wiring board has been designed to minimize
ground loop currents with particular attention to reducing
EMI generation. The use of the Graphical User Interface
(GUI) enables the user to control motor speed and set the
basic control parameters such as PWM frequency and shut
down conditions via the serial link.
The micro controller generates the constant volt-seconds
PWM signals from the instructions entered into the GUI. The
GUI also displays all the micro controller parameters. This
feature enables the user to monitor the actual operation
parameters in real time. Three LEDs are used to monitor
the electrical status of the control board:
All the protection functions are enabled by the software. The
micro controller monitors the DC bus voltage and current
and the heat sink temperature. Shut down is activated if
one of the following conditions is present:
The GUI will display which fault has been detected and guar-
antees complete protection for the power stage. The maxi-
mum case temperature can be set through the GUI from
25°C to 100 °C.
The auxiliary power supply uses a UC3842D single ended
current mode PWM controller in a buck topology with linear
post regulators to deliver 5V and 15V DC referenced to the
DC bus return. The auxiliary power supply operates open
loop at 50KHz with a fixed duty cycle. Voltage regulation is
maintained over a DC bus voltage variation from 60VDC to
400VDC.
