Eval Board Enables Complete Motor Drive Set-up in One Hour

The Eval-M3-CM615PN from Infineon is a new power board for iMOTION™ Modular Application Design Kit (MADK) that creates a powerful inverter + PFC system. With this board and its matching iMOTION control board EVAL-M3-102T, designers can complete motor drive system set-up within one hour.

It enables easy evaluation of IFCM15P60GD based on CIPOS™ Mini IPM technology, combining a 3-phase inverter stage and a PFC stage based on TRENCHSTOP™ IGBTs. The evaluation also allows rapid prototyping of motor control systems for fans, pumps and compressors, combined with active PFC.

Eval-M3-CM615PN is an evaluation board as part of the iMOTION™ Modular Application Design Kit. This power board includes a PFC integrated 3-phase CIPOS™ Mini Intelligent Power Module (IPM) for motor drive application.

In combination with the control board equipped with the M3 30pin interface connector such as EVAL-M3-102T, it features and demonstrates Infineon’s CIPOS™ Mini IPM technology and Advanced Motion Control Engine (MCE 2.0) technology for permanent magnet motors drive over the full speed range.

The inverter section has 600V of voltage and 15A of current rating, and the PFC section has 650V of voltage and 30A of current rating. It is optimized to major home appliances like air conditioners and low power motor dirve application with high frequency switching operation of power factor correction.

This evaluation board Eval-M3-CM615PN was developed to support customers during their first steps designing applications with CIPOS™ Mini PFC integrated IPM IFCM15P60GD and running any permanent magnet motor via sensorless sinusoidal control.

The MADK platform is intended to use various power stages with different control boards. These boards can easily be interfaced through the 30-pin iMOTION™ MADK M3 such as Eval-M3-102T, or the 20-pin iMOTION™

MADK M1 interface connector to control board. This board is equipped with 30-pin M3 connector and is intended for single motor control only.

This evaluation board is designed to give Easy-to-use power stage based on the Infineon’s CIPOS™ Mini Inteligent Power Module (IPM). The board is equipped with all assembly groups for sensorless field oriented control (FOC).

It provides a single-phase AC-connector, rectifier, a PFC inductor connector, Boost PFC and 3-phase output for connecting the motor. The power stage also contains emitter shunts for current sensing and a voltage divider for DC-link voltage measurement.

The block diagram of the Eval-M3-CM615PN is depicted in the figure below. This evaluation board includes an  EMI filter and soft power up circuit, 30 pins iMOTION™ MADK-M3 interface connector, auxiliary power supply to provide 15V and 3.3V, PFC gate dirve circuit and the CIPOS™Mini IPM IFCM15P60GD.

The hardware circuit regarding overtemperature and overcurrent protection is also included in this power board. The sense connection to common emitter shunt resistor is connected to the 30 pins iMOTION™ MADK-M3 interface connector. This power board is compatible with PFC integrated CIPOS™ Mini IPMs that feature 3 phase common emitter and built-in NTC considering motor power rating and IPM’s current rating.
