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

3.2.4 Programming Hall sensor TLI4971
The evaluation board uses two TLI4971-A025T5-E0001 Hall sensors for current sensing. One sensor is used for
PFC current sensing and the other one is used for inverter current sensing. The Hall sensor TLI4971 is a high-
precision, coreless current sensor for industrial applications in an 8 x 8 SMD package. These sensors are
configured in a single-ended mode, in which an external analog reference voltage VREF is provided as an input.
All user-programmable parameters, such as overcurrent detection (OCD) thresholds, deglitching filter settings,
and output configuration mode are stored in an embedded EEPROM memory. This memory can be
programmed in the application through a serial inspection and configuration interface (SICI). A current sensor
programmer board and a GUI software tool are required to program the sensor. This tool can be downloaded
from Infineon’s website (link). The current sensor programmer board (link) is essential to program the EEPROM
memory. Figure 10 shows the Hall sensor EEPROM programming window. For programming details, please
download the application note and datasheet for the programming guide and the user manual from Infineon’s
website.

EVAL-IKA15N65ET6 User Guide
Getting started
For programming TLI4971, the programmer board’s output terminal should be connected to the EVAL-
IKA15N65ET6 board, as shown in Figure 11. The programmer board has three channels for connecting three
sensors at the same time. For EVAL-IKA15N65ET6, users can use two channels to connect the two Hall sensors,
as shown in Figure 11, and then select sensor 1 or sensor 2 to program the two TLI4971 sensors in the
programming pop-up window. Of course, only one channel is needed to program the two Hall sensors
separately; there is no need to connect the sensors together. For example, when users use channel 1 to
program the PFC current sensor, they only need to connect programmer connector pins 1, 4, 14, and 20 with
TP2, TP1, TP5, and TP6, respectively, on the evaluation board. After programming the PFC Hall sensor, users
need to keep pin 14 and pin 20 connections for 3.3 V and GND. Pin 1 and pin 4 connections can be moved to TP7
and TP8 on the evaluation board for programming the inverter current sensor.
When programming the Hall sensor, the jumper cap must be unplugged from the connector J8 on the EVAL-
IKA15N65ET6 board. After finishing the TLI4971 programming, the jumper cap should be plugged in again to J8.

Hardware description
4Hardware description
All necessary technical data such as schematic diagrams, layouts, and components that are needed to meet
customer requirements and make EVAL-IKA15N65ET6 a basis for development or modifications are described
in this chapter.
This evaluation board consists of the following functional blocks:
•Motor controller
•PFC stage
•3-phase power stage
•Current sensing
•Auxiliary power supply
4.1 Motor controller
The board uses the iMOTION™ IMD112T-6F040 smart driver as the motor controller. IMD112T-6F040 is part of
the IMD110 series of highly integrated ICs for controlling variable speed drives. It integrates the motor
controller with a high voltage, 3-phase gate driver and a voltage regulator in a single package.
Controller’s PWM outputs are internally connected to the gate driver inputs. Two controller digital pins are also
connected to the gate driver’s enable input and fault output. The integrated voltage regulator generates 5 V to
supply the controller and can share the same 15 V supply rail as the gate driver.
The motor controller uses the Motion Control Engine to create a ready-to-use solution to control the PMSM,
providing the shortest time to market for any motor system at lowest system and development cost. The
integrated script engine provides application flexibility to users without interfering with the motor and PFC
control algorithm.
4.2 PFC stage
The EVAL-IKA15N65ET6 board contains a boost PFC stage to reduce the reactive power and total harmonic
distortion (THD) in the grid.
The PFC function on the evaluation board is performed by TRENCHSTOP™ 5 WR6 IGBT IKWH30N65WR6
combined with the silicon power diode IDW30E65D1. The TRENCHSTOP™ 5 WR6 IGBT in a high creepage and
clearance TO-247-3-HCC package is optimized for PFC topologies. The Rapid 1 silicon power diode in a TO-247
package has excellent compatibility with the IGBT.
PFC shapes the input current of the power supply to be synchronized with the mains voltage to maximize the
real power drawn from the mains. In an ideal PFC circuit, the input current follows the input voltage as a pure
resistive load, without any input current harmonics.
The main stage schematic for EVAL-IKA15N65ET6 is shown in Figure 12.
