Safety precautions
1 Safety precautions
In addition to the precautions listed throughout this manual, please read and understand the following
statements regarding hazards associated with development systems.
Table 1 Precautions
Attention: The ground potential of the EVAL-M1-05-65D system is biased to a negative DC
bus voltage potential. When measuring voltage waveform by oscilloscope, the
scope’s ground needs to be isolated. 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.
Attention: EVAL-M1-05-65D system contains DC bus capacitors which take time to
discharge after removal of the main supply. Before working on the drive
system, wait three 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.
Attention: Only personnel familiar with the drive and associated machinery should plan
or implement the installation, start-up and subsequent maintenance of the
system. Failure to comply may result in personal injury and/or equipment
damage.
Attention: The surfaces of the drive may become hot, which may cause injury.
Attention: EVAL-M1-05-65D system contains parts and assemblies sensitive to
Electrostatic Discharge (ESD). Electrostatic control precautions are required
when installing, testing, servicing or repairing this assembly. Component
damage may result if ESD control procedures are not followed. If you are not
familiar with electrostatic control procedures, refer to applicable ESD
protection handbooks and guidelines.
Attention: A drive, incorrectly applied or installed, can result in component damage or
reduction in product lifetime. Wiring or application errors such as under sizing
the motor, supplying an incorrect or inadequate AC supply or excessive
ambient temperatures may result in system malfunction.
Attention: Remove and lock out power from the drive before you disconnect or reconnect
wires or perform service. Wait three minutes after removing power to
discharge the bus capacitors. Do not attempt to service the drive until the bus

Introduction
2 Introduction
The EVAL-M1-05-65D evaluation board is a part of the iMOTION™Modular Application Design Kit for drives
(iMOTION™MADK).
The MADK-platform is intended to use various power stages with different control boards. These boards can
easily be interfaced through the 20 pin iMOTION™MADK-M1 interface connector.
This evaluation board is designed to give comprehensible solutions of a power stage featuring µIPM™-DIP. The
board is equipped with all assembly groups for sensor less field oriented control (FOC). It provides a single-
phase AC-connector, rectifier, DC-link and 3-phase output for power. It contains emitter-shunts for current
sensing and a voltage divider for DC-link voltage measurement.
The EVAL-M1-05-65D evaluation board is available from Infineon. The features of this board are described in the
design feature chapter of this document, whereas the remaining paragraphs provide information to enable the
customers to copy, modify and qualify the design for production according to their own specific requirements.
Environmental conditions were considered in the design of the EVAL-M1-05-65D. The design was tested as
described in this document but not qualified regarding safety requirements or manufacturing and operation
over the whole operating temperature range or lifetime. The boards provided by Infineon are subject to
functional testing only.
Evaluation boards are not subject to the same procedures as regular products regarding Returned Material
Analysis (RMA), Process Change Notification (PCN) and Product Discontinuation (PD). Evaluation boards are
intended to be used under laboratory conditions by specialists only.
Figure 1 Evaluation-board EVAL-M1-05-65D
Figure 1 shows the evaluation board EVAL-M1-05-65D. Although this board is compatible with on surface mount
as well as through whole CIPOS™Micro modules. This document explains the features and details of this board
in combination with CIPOS™Micro IRSM515-065 and IRSM505-065. The only difference between these modules
is the presence of a NTC. IRSM505-065 has a NTC and IRSM515-065 does not. Both modules are rated 500 V.
Ratings and other details of the board are explained in the subsequent sections.

General information about the connectors of the EVAL-M1-05-65D evaluation board is reported. Table 5
includes the details of the line connector J1-AC. It is possible to connect DC voltage to the AC connector. In this
case a permanent DC-current will be conducted through the rectifier bridge. Maximum ratings are valid for AC
as well as DC conditions. It is recommended to observe the temperature of the rectifier bridge. Due to the
rectifier, DC supply’s polarity at the connector is of no concern.
The evaluation board doesn’t have a fuse. An external fuse is highly recommended during testing.

By default, R14 is not mounted on Eval-M1-05-65D. There must be a pull-down resistor mounted on the
corresponding control card.
Figure 11 DC bus sense resistor on EVAL-M1-05-65D evaluation board
If a pull down resistor of 4.87 kΩreferred to ground is inserted either on the Eval-M1-05-65D evaluation board
or on the control board, the DCBSENSE voltage results in the range of 0 to 3.3 V on the pin reflecting a DC bus
voltage range of 0 to 400 V.
If a pull down resistor of 4.87 kΩis inserted on both, Eval-M1-05-65D evaluation board and on the control card,
the DCBSENSE results scale to 0-1.65 V. No safety issue occurs.
If no feedback is desired on the DCBSENSE-pin, R13A or R13B should be removed to avoid high voltage on the
connector.

6.3 EMI input filter and rectifier circuit
Figure 12 depicts the schematic from the AC line input connector J1 to the rectified DC bus voltage. This
circuitry includes a passive EMI filter consisting of elements CX1, CX2, L1, CY1 and CY2, a 4 A/600 V rectifier block
BR1 and a NTC resistor RT1 for surge current protection. An electrolytic capacitor C1 and two ceramic
capacitors C10 and C11 are used for buffering the rectified DC bus voltage DCP. During testing it is advisable to
include an external fuse.

6.4 Inverter section using CIPOS™Micro
The inverter section is implemented using the CIPOS™Micro IPM as sketched in Figure 13. The module includes
six power MOSFETs and three half bridge gate drivers. The shunt resistor section is also given, including the 0Ω
resistors R22 to R27. These resistors allow connecting or disconnecting the shunts’ signals to connector J3. The
three capacitors C29, C31 and C33 are used as bootstrap capacitors to provide the necessary floating supply
voltages VBS1, VBS2 and VBS3 respectively.
