We offer you a broad portfolio of efficient semiconductors optimized for motor. You can rely on our intelligent power modules (IPMs) and discretes for smart designs in the low-power range. For medium-power drives, our EasyPIM™, EasyPACK™, and EconoPIM™ modules are the perfect match. Moving on to the high-power spectrum, EconoDUAL™ and PrimePACK™ are the solutions of choice. Combined with the innovative.XT interconnection technology, PrimePACK™ modules can help designers overcome the overrating dilemma as they extend the lifetime by raising thermal and power cycling capabilities.
Highlights of our portfolio include our TRENCHSTOP™ IGBT7 modules, tailored specifically to the needs of drive applications. Ideal for general-purpose drive (GPD) applications, TRENCHSTOP™ IGBT7 devices improve power density, controllability, and overload capability in a variety of proven packages for cost and time gains. For high-speed drives and inverter integration, our CoolSiC™ MOSFETs are an attractive solution as they reduce switching and conduction losses, especially under partial load conditions.
Complementing our power semiconductors, we also offer gate driver ICs for all silicon and silicon carbide (SiC) devices. Our broad EiceDRIVER™ portfolio scales from basic to enhanced functionality. For battery-powered applications like automotive brushless DC motors, customers can rely on our wide range of silicon MOSFETs including our OptiMOS™ family. To round out this offering and make your design ready for Industry 4.0, we support rising connectivity needs with iMOTION™, XMC™, and AURIX™ microcontrollers, complemented by OPTIGA™ Trust solutions for the highest security standards. These devices can be combined with sensors from our XENSIV™ family to bring more sensory intelligence to your design and enable innovative features such as predictive maintenance.

Application
Also check whether your customer has any special requirements, such as: vibration resistance; Long life; high temperatures; very high speed; heatsink type (water or air-cooled); overload conditions as shown in the figures.
What is your specific application? -
The five key questions to design a drives inverter
Application cont.
In drive applications is the limitation of switching speed due to the limitation of the motor insulation system. Therefore, switching slopes (dv/dt) are restricted to a range of 2 to 10 kV per microsecond (kV/µs) with a typical target of 5 kV/µs.

Current
While motor power classes are standardized, the output currents differ a little from one manufacturer to another. There are many factors that can have an impact here, such as: power factor; motor efficiency; modulation scheme

Voltage
Selecting the right voltage class depends on the grid input voltage. Note that the maximum DC link voltage can have a tolerance of 10%. This value should not exceed two-thirds of the blocking voltage of an IGBT due to cosmic ray reliability.

Topology
Does the application require a brake switch? Let’s take a closer look at the rectifier: is it a single, active frontend or a 3-phase design? If it is a 3-phase rectifier, how is it controlled?

The five key questions to design a drives inverter
Topology cont.
For drives up to 22 kW, customers typically use PIM modules. In the 30 to 90 kW range, they use sixpack modules or half-bridges. Above 90 kW, they only use half-bridge modules. If designing servo drives, customers typically use sixpack or PIM modules

Frequency
Industrial drives applications usually operate with moderate switching frequencies when compared to other applications. Normally, 4 kilohertz is a typical value. As you can see in the graphic, increased switching frequency can reduce audible noise.
What is the switching frequency?
The unique and specific requirements of motor drive systems demand a new approach to IGBT design. With the right IGBT technology, it is possible to create better-positioned modules to address these needs. This approach Infineon has taken with its latest generation of IGBT technology, the IGBT7.
At the chip level, the IGBT7 uses micro-pattern trenches (MPT), the structure of which contributes significantly to reducing forward voltage and increased conductivity in the drift zone. For applications with a moderate switching frequency, such as motor drives, the IGBT7 delivers a significant reduction in previous generations' losses. Another improvement offered by IGBT7 from a generation earlier (IGBT4) is the freewheeling diode that has also been optimized for drive applications. The forward voltage drop of the emitter controlled diode, EC7, is now 100 mV lower than the forward voltage drop of the EC4 diode, with improved reverse-recovery softness. Learn more
With more automation being used across industries, there is a correspondingly increased demand for servo motors. Their ability to combine precise motion control with high torque levels makes them the perfect fit for automation and robotics.
Using its manufacturing expertise and long experience, Infineon has developed a SiC trench technology that offers higher performance than the IGBT but with comparable robustness, e.g., short-circuit time of two (or 2) µs or even three (or 3) µs. Infineon's CoolSiC™ MOSFETs also address potential problems inherent in SiC devices, such as unwanted capacitive turn-on. Furthermore, the SiC MOSFETs are available in the industry-standard TO247-3 package, and now with even better switching performance, in the TO247- 4 package. In addition, the CoolSiC MOSFETs are also available in the SMD package TO267-7. Besides these TO-packages, the SiC MOSFET is also available in Easy 1B, Easy 2B, and 62mm packages. Learn more
