User Guide for REF-DR3KIMBGSICMA
Reference design for motor drive integration
About this document
Scope and purpose
This user guide provides an overview of the reference board REF-DR3KIMBGSICMA including its main features,
key data, pin assignments and mechanical dimensions.
REF-DR3KIMBGSICMA is a reference design contains two PCBs (named as driver board and power board
respectively), including driver circuit and a three-phase inverter for motor-drive application. The driver circuit
is based on EiceDriverTM IC - 1EDI20I12MH with miller clamp function. CoolSiCTM MOSFET – IMBG120R45M1H is
the main component for the three-phase inverter.
The REF-DR3KIMBGSICMA was developed to support customers during their first steps in designing with
EiceDriverTM IC and CoolSiCTM MOSFET for a servo motor with inverter integration. This reference design is the
power part of demonstration of the integrated servo motor, which is an Infineon joint development project
with partner JingChuan and Maxsine.
Intended audience
This user guide is intended for all technical specialists working with the REF-DR3KIMBGSICMA.
Reference Board/Kit
The Infineon product(s) are embedded on this PCB with functions and form factor close to a commercial
design. PCB and auxiliary circuits are optimized for the final design.
Note: Boards do not necessarily meet safety, EMI, quality standards (for example UL, CE) requirements.

Important notice
“Evaluation Boards and Reference Boards” shall mean products embedded on a printed circuit board
(PCB) for demonstration and/or evaluation purposes, which include, without limitation, demonstration,
reference and evaluation boards, kits and design (collectively referred to as “Reference Board”).
Environmental conditions have been considered in the design of the Evaluation Boards and Reference
Boards provided by Infineon Technologies. The design of the Evaluation Boards and Reference Boards

Safety precautions
Safety precautions
Please note the following warnings regarding the hazards associated with development systems.
Table 1 Safety precautions
Warning: The DC link potential of this board is up to 1000 VDC. When measuring
voltage waveforms by oscilloscope, high voltage differential probes must be used.
Failure to do so may result in personal injury or death.
Warning: The evaluation or reference board contains DC bus capacitors which take
time to discharge after removal of the main supply. Before working on the drive
system, wait five minutes for capacitors to discharge to safe voltage levels. Failure to
do so may result in personal injury or death. Darkened display LEDs are not an
indication that capacitors have discharged to safe voltage levels.
Warning: The evaluation or reference board is connected to the grid input during
testing. Hence, high-voltage differential probes must be used when measuring voltage
waveforms by oscilloscope. Failure to do so may result in personal injury or death.
Darkened display LEDs are not an indication that capacitors have discharged to safe
voltage levels.
Warning: Remove or disconnect power from the drive before you disconnect or
reconnect wires, or perform maintenance work. Wait five minutes after removing
power to discharge the bus capacitors. Do not attempt to service the drive until the bus
capacitors have discharged to zero. Failure to do so may result in personal injury or
death.
Caution: The heat sink and device surfaces of the evaluation or reference board may
become hot during testing. Hence, necessary precautions are required while handling
the board. Failure to comply may cause injury.
Caution: Only personnel familiar with the drive, power electronics and associated
machinery should plan, install, commission and subsequently service the system.
Failure to comply may result in personal injury and/or equipment damage.
Caution: The evaluation or reference board contains parts and assemblies sensitive to
electrostatic discharge (ESD). Electrostatic control precautions are required when
installing, testing, servicing or repairing the assembly. Component damage may result
if ESD control procedures are not followed. If you are not familiar with electrostatic
control procedures, refer to the applicable ESD protection handbooks and guidelines.
Caution: A drive that is incorrectly applied or installed can lead to component damage
or reduction in product lifetime. Wiring or application errors such as undersizing the
motor, supplying an incorrect or inadequate AC supply, or excessive ambient
temperatures may result in system malfunction.
Caution: The evaluation or reference board is shipped with packing materials that
need to be removed prior to installation. Failure to remove all packing materials that
are unnecessary for system installation may result in overheating or abnormal
operating conditions.
