IRMCF341 in the application of variable frequency electrical appliances

 IRMCF341 international rectifier (IR) in the United States new sensorless control for variable frequency electrical appliances application of high performance low cost motor control IC. It adopts the most advanced based on the motor vehicle spare parts magnetic field orientation vector control technology, using the single resistance current sampling the motor can be realized in three phase current refactoring, so as to realize the FOC current loop and speed AC synchronous generator loop, double closed-loop vector control, drive mode for 180 degrees of sine wave. IRMCF341 contains two high-performance processing engine, one is 8 bits high- speed 8051 cores, generator set spare parts the other one is to control the motor sensorless control of 16 engines (MCE). 8051 nuclear execution speed for every two system clock an instruction (such as: 60 MIPS @ 120 MHZ system clock). 8051 nuclear and MCE processor: by dual port RAM data exchange between so as to realize the function of data monitoring and command input. 


MCE contains all the necessary based on hardware circuit control motor control resources, such as PI regulator, vector rotation, Angle estimator, multiplication/divider, low loss of SVPWM, and single resistance current sampling/restructuring, and so on. Sensorless control algorithm of the key elements of complex (such as: Angle estimator) all have defined acmotortrading.blogspot.com control module, the user can through the use of the seamless connection with MATLAB/SIMULINK environment graphical compiler to design your own motor control algorithm (in MATLAB/SIMULINK environment by connecting the modules function module and compiles). 8051 code simulation and debugging can be through a third party based on JTAG mouth debugging tools to complete. Procedure in 51 IRMCF341 memory to 48 k RAM, packaging form for small QFP64 lead-free packaging.
