The CIPOS™ Maxi IM818 product group offers the chance for integrating various power and control components to increase reliability, optimize PCB size and system costs. It is designed to control three phase AC motors and permanent magnet motors in variable speed drives applications such as low power motor drives (GPI, Servo drives), pumps, fan drives and active filter for HVAC(Heating, Ventilation, and Air Conditioning). The product concept is specially adapted to power applications, which need good thermal performance and electrical isolation as well as EMI save control and overload protection.
Three phase inverter with 1200V TRENCHSTOP™ IGBTs and Emitter Controlled diodes are combined with an optimized 6-channel SOI gate driver for excellent electrical performance.

Maxi IM818主要特性:

 Fully isolated Dual In-Line molded module
 1200V TRENCHSTOP™ IGBT4
 Rugged 1200V SOI gate driver technology with stability against transient and negative voltage
 Allowable negative VS potential up to -11 V for signal transmission at VBS = 15 V
 Integrated bootstrap functionality
 Over current shutdown
 Built-in NTC thermistor for temperature monitor
 Under-voltage lockout at all channels
 Low side emitter pins accessible for all phase current monitoring (open emitter)
 Cross-conduction prevention
 All of 6 switches turn off during protection
 Programmable fault clear timing and enable input
 Lead-free terminal plating; RoHS compliant

评估板EVAL-M1-IM818-A

EVAL-M1-IM818-A is a complete evaluation board including a 3-phase CIPOS™ Maxi Intelligent Power Module(IPM) for motor drive application. In combination with control-boards equipped with the M1 20pin interfaceconnector, like EVAL-M1-101T or EVAL-M1-099M, it features and demonstrates Infineon’s CIPOS™ Maxi IPMtechnology for motor drive.

The evaluation board EVAL-M1-IM818-A was developed to support customers during their first stepsdesigning applications with CIPOS™ Maxi IPM.

CIPOS™ Maxi IPM in this board is IM818-MCC which has three phase inverter with 1200V TRENCHSTOP™IGBTs and Emitter Controlled diodes are combined with an optimized 6-channel SOI gate driver. It isOptimized to industrial applications like Ventilation and Air Conditioning.

The EVAL-M1-IM818-A 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 caneasily be interfaced through the iMOTION™ MADK M1 interface connector which is 20 pin connector.

This evaluation board is designed to give easy-to-use power stage based on the Infineon ’ s CIPOS™ MaxiInteligent Power Module (IPM). The board is equipped with all assembly circuit for sensorless field orientedcontrol (FOC). It provides a single-phase AC-connector, rectifier and 3-phase output for connecting themotor. The power stage also contains emitter (leg) shunts for current sensing and a voltage divider for DClinkvoltage measurement.

The EVAL-M1-IM818-A evaluation board is available through regular Infineon distribution partners as well ason Infineon’s website. The features of this board are described in the design feature chapter of thisdocument, whereas the remaining paragraphs provide information to enable the customers to copy, modifyand qualify the design for production according to their own specific requirements.

Environmental conditions were considered in the design of the EVAL-M1-IM818-A. The design was tested asdescribed in this document but not qualified regarding safety requirements or manufacturing and operationover the whole operating temperature range or lifetime. The boards provided by Infineon are subject tofunctional testing only.

Evaluation boards are not subject to the same procedures as regular products regarding Returned MaterialAnalysis (RMA), Process Change Notification (PCN) and Product Discontinuation (PD). Evaluation boards areintended to be used under laboratory conditions and by trained specialists only.

The block diagram of the EVAL-M1-IM818-A is depicted in Figure 1. This evaluation board includes a DC EMIfilter and soft power up circuit, 20-pin iMOTION™ MADK-M1 interface connector, auxiliary power supply toprovide 15 V and 3.3 V, and the CIPOS™ Maxi IPM IM818-MCC.
