Efficient motor drive designs at lowest system costs

3-Phase Motor Drive Application Kit significantly shorten Time-to-Market

Addressing the increasing need for advanced motor drive solutions Infineon offers a new 3-phase motor drive application kit for permanent magnet synchronous motors (PMSM) and induction motors (ACIM). The key components of the kit are the 8-bit XC886 MCU capable of running field oriented control (FOC), the CIPOS™ intelligent power module (IPM), the on-board switched mode power supply (SMPS) based on COOLSET™ and a complete software package. The usage of the kit shorten timeto- market for energy efficient motor control designs with excellent speed control, reduced noise and high system reliability. Target applications are white goods such as washing machines and various industrial motor control applications, e.g. pumps, fans, etc.

The combination of the FOC capable XC886 MCU and the CIPOS power module offers excellent electrical performance at low costs and reduces board space requirements. The on-board SMPS based on COOLSET™ enables quick start-up and evaluation. Optimized motor control software as well as the digitally isolated real time monitoring tool makes the kit an easy-to-use reference platform. The power stage is capable of driving both PMSM and ACIM motors with power rating of up to 750W peak load.

Powerful MCU

FOC is a powerful technique for operating electric motors resulting in smooth and energy efficient operation at all speeds. Implemented on its 8-bit XC886 and XC888 families, Infineon brings FOC motor control solutions to price-sensitive applications. The XC886 microcontroller with the in-built 16-bit Vector Computer enables customers to develop cost-effective sensorless motor controls which are precise, highly responsive and energy efficient, even at highest torque. In addition the XC886 provides a powerful peripheral set including a PWM unit for advanced motor control (CapCom6E) and a fast 10-bit ADC with a conversion time of less then 1.5 ìs.

High integrated IPM

The CIPOS module incorporates a three-phase inverter power stage with a SOI (Silicon- On-Insulator) gate driver, boot strap diodes and capacitors, and auxiliary circuitry in a compact fully isolated package. Based on a combination of Infineon’s leading-edge TrenchStop™ IGBTs with lowest VCEsat = 1.6 V @ 25 °C and EmCon™ (Emitter Controlled) diode technology, the IPM significantly reduces the BOM compared to designs based on discrete components. The fully isolated package offers best-in-class thermal resistance and the CIPOS module shows a high ruggedness against negative transient voltage.

On-board SMPS

The kit Integrates a PWM & protection control IC with a high voltage power MOSFET (COOLSET™) which offers a very low standby power of less than 100mW and best-inclass on-resistance.

Software

The complete software package includes:
- DriveMonitor with Graphical User Interface (GUI) for real time control/monitoring and USB-CAN bridge
- Optimized sensor less FOC source code for PMSM
- Source code for V/f control for ACIM for quick evaluation
- Free tool chain including SDCC compiler and IDE
- Fast flash programming via JTAG
