Hello, I would like to know the maximum PWM carrier frequency supported by the following fast current loop technology?Or the maximum switching frequency that can be achieved using fast current loop technology
Hi. The execution time of the FCL would be 1-2us, which can support switching frequencies up to 500Khz. Do you have any specific requirement on the FSW?
Thank you very much for your help in your busy schedule!I am trying to build a multi-axis high-speed motor control using FSI and FCL, and the two motors are connected coaxial. The rotor position of the second motor and the given value of the current loop are calculated by the controller of the first motor and then sent to the controller of the second motor through FSI, which means that there is no QEP in the controller of the second motor, but the rotor position information is directly obtained. In this case, can I use the FCL algorithm provided by TI in the second motor controller?
Thanks for your help! After the controller receives the position information sent by the FSI, can the FCL complete the calculation and generate PWM within 2us?
