Infineon has expanded the portfolio of application kits for its 8-bit and 16-bit microcontrollers, introducing scalable reference designs for motor drives which ease the evaluation and implementation of hardware and software solutions for highly efficient drives.
The new kits are built around members of the 8-bit XC800 and 16-bit XE166 family supporting advanced motor control techniques like field oriented control (FOC) and power factor control (PFC). These sophisticated control techniques are increasingly used in consumer and industrial drives by addressing the design focus on higher efficiency, better dynamic response and reduced audible noise.
The three new application kits increase the scalability of reference systems for motor drive applications. The Dual Motor Drive Kit, based on the XC878 and XE166, improves energy efficiency supporting both FOC and PFC with a scalable solution from 8-bit to 16-bit and a power board driving up to 8 A at 110–230 V. The FOC Motor Drive Kit enables FOC for XC878 and XE166 with a power board capable of driving up to 7,5 A at 23–56 V. The 12 V-Brushless DC Drive Kit uses the XC866 and eases BLDC (brushless DC) motor drive design with the capability to drive motors with up to 20 A at 9–18 V.
All application kits contain a free tool chain including compiler and debugger and offer plug-and-play design, as all related hardware and software parts are provided. A USB to JTAG and CAN bridge allows digital isolated realtime monitoring. All new kits are ready to be used with Dave Drive, Infineon’s auto code generator for motor drives.
12 V-Brushless DC Drive Application Kit
With the 12V-Brushless DC Drive Application Kit, BLDC designers can implement the advanced techniques that make their design more reliable and get more power from existing motors, applying simple algorithms that increase control flexibility and improve efficiency. The user can examine the trade-offs of block commutation with Hall sensors versus sensorless control and determine which approach is best for their applications like pumps, fans, valves or power tools.
The drive card of the kit is built around the 8-bit XC866 MCU providing the timer unit CAPCOM6E for flexible PWM generation, a fast 10-bit ADC with 1,5 μs conversion time and embedded Flash memory up to 16 KB. The power board provides an inverter circuit capable of driving BLDC motors up to 20 A. The inverter is made by combining three NovalithIC motor drivers from Infineon, providing a low ohmic-protected half-bridge in a single package. The application kit includes a BLDC motor for first experimentation.
The software package includes a free tool chain including SDCC compiler and HiTOP debugger and software examples showing sensored, sensorless, phase-advance and 12-step control methods for motor control. A comprehensive video tutorial guides the user during setup and usage of the kit.
Dual Motor Drive Application Kit
The Dual Motor Drive Application Kit offers a scalable solution for FOC and PFC. It is built around the 8-bit XC878 and 16-bit XE164, both supporting FOC and PFC by architecture. The power board is capable of driving two motors such as a PMSM independently with Infineon’s EiceDRIVER gate driver IC, CIPOS intelligent power module and CoolSET power management IC.
Provided with optimised motor control software as well as a digitally isolated realtime monitoring tool, the kit offers an easy-to-use reference platform for industrial drives in fans, blowers, pumps, white goods or airconditioners. It is a platform to evaluate the performance of realtime capabilities of the Infineon microcontrollers and enables evaluation of energy efficient motor control designs targeting excellent torque dynamics, reduced noise and high system reliability.
The kit contains two drive cards; one is based on the XC878 which provides a vector computer, two independent PWM units and a fast ADC with 1,5 μs sample time. This device can run FOC and PFC in parallel. The second drive card is equipped with the XE164 offering a MAC unit, three independent PWM units and two independent fast ADCs. With the XE164, users can drive two motors and run a PFC in parallel. The power board (11–230 V a.c., 8 A) provides an inverter with 900–1800 W, a second inverter with 100–200 W and a boost converter for PFC.
The complete software package, including source code, enables simultaneous control of two PMSMs with sensorless FOC and digital PFC using the XE164 or the XC878. In addition, V/f control of induction motors is provided for quick evaluation.
FOC Motor Drive Application Kit
The FOC Motor Drive Application Kit is a scalable solution for FOC applications, built around the 8-bit XC878 microcontroller and the 16-bit XE164. The power stage is capable of driving a PMSM with Infineon’s EiceDRIVER gate driver IC, OptiMOS MOSFETs and the CoolSET power management IC.
The kit comes with two drive cards, one based on the XC878 and the other one using the XE164. The power board (23–56 V, 7,5 A) drives a 15 W PMSM motor which is part of the kit. A plug-in 24 V power supply completes the hardware. The software package includes optimised source code for sensorless FOC of PMSM for the XE164 and XC878 with PI controllers for speed and two currents. It allows an easy configuration of the motor parameters. The source code for V/f control for ACIM for quick evaluation is provided with the kit.
This kit targets FOC implementation in applications such as washing machines, refrigerators, industrial drives, electrical power steering, electric vehicle traction drive, air conditioning, fans, blowers and pumps.
