Infineon IRMCK099永磁马达无传感器控制方案

Infineon公司的IRMCK099是基于运动控制ASIC的低成本高性能无传感器马达控制集成电路,包含了iMOTION™马达控制引擎(MCE)和实现变速驱动的所有外设,不需要算法编程,能和μIPM™或分立功率级使用,单电源3.3V,主要用在无人机,四螺旋桨遥控直升机,家用电器,电泵和风扇以及其它永磁马达(PMSM)驱动.本文介绍了IRMCK099主要特性,产品概述,框图和典型应用框图,以及马达控制参考设计EVALM1099M主要特性和主要指标,电路图,材料清单和PCB设计图.

The IRMCK099 combines the iMOTION™ motor control engine (MCE) with all peripherals required to realize a complete variable speed drive. The IRMCK099 does not require algorithm programming and can be used in combination with a μIPM™ or a discrete power stage.

The MCE implements sensor less field oriented control using single or leg shunt current feedback and uses space vector PWM with sinusoidal signals to provide highest energy efficiency.

IRMCK099 is a low cost, high performance OTP memory based motion control ASIC designed primarily for appliance applications. IRMCK099 is designed to implement high performance control solutions for advanced inverterized appliance motor control. IRMCK099 contains the flexible Tiny Motion Control Engine (TinyMCE) for sensorless control of permanent magnet motors over the full speed range. The TinyMCE implements sensorless Field Oriented Control using single or leg shunt current feedback by a combination of hardware and IR-supplied firmware elements. Key components of the complex sensorless control algorithms, such as the Angle Estimator, are provided as complete pre-defined control blocks. The ASIC is designed to eliminate external components and reduce cost by including an A/D converter, analog amplifiers, an overcurrent comparator, watchdog timer and internal oscillator. Strong startup and configuration tools get the motor running quickly without any programming. A standby power mode can help to increase overall system efficiency. IRMCK099 comes in a 5mmx5mm, 32 pin QFN pack...
