AN2019-19 EVAL-M1-2ED2106S User Manual EVAL-M1-2ED2106S User Manual 2ED2106S06F Evaluation board for BLDC motor drives About this document Scope and purpose This application note provides an overview of the evaluation board EVAL-M1-2ED2106S concerning its main features, hardware description, thermal performance and typical waveforms, etc. The EVAL-M1-2ED2106S board is a power drive board including driver ICs, IGBTs, a power connector and signal interface. The board is intended to drive a brushless direct current (BLDC) motor by connecting to an external controller board such as EVAL-M1-101T. The board aims to boost Infineons newly promoted 650 V high and low side gate driver 2ED2106S06F using the silicon-on-isolator (SOI) technology. Intended audience This application note is intended for all technical specialists likely to evaluate the 650 V SOI gate drivers for general applications.

Table 1 Safety precautions Caution: The ground potential of the EVAL-M1-2ED2106S board is biased to a negative DC bus voltage potential. When measuring voltage waveform by oscilloscope, the ground of the device needs to be isolated. Failure to do so may result in personal injury or death, and equipment damage. Caution: 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. Caution: The surfaces of the drive may become hot, which may cause injury. Caution: The EVAL-M1-2ED2106S board 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. Caution: An incorrectly applied or installed drive can result in component damage or reduction in product lifetime. Wiring or application errors such as undersized motor, incorrect or inadequate DC supply, or excessive ambient temperatures may result in system malfunction. Caution: Remove or connect the control board from, or to, the power drive. Wait three minutes after removing power from the power drive 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. User Manual 2 of 29 Revision 1.0 2019-09-18
