Hi Champs,
I am designing an ESC for my customer. TMS320F28027F+DRV8305+NexFET are being promoted to customer, and the control method is sensorless FOC. The system specs are as follows:
1. 22.2V DC bus voltage (6S lithium battery);
2. DC bus current would be high to 30A with maximum speed;
From my understanding, 40V or 60V MOSFET would be good enough. Would you suggest how to choose the Id? And also would you help to explain the terms "Continuous Drain Current (Package limited)" and "Continuous Drain Current (Silicon limited)"
Thanks a lot.
BR,
Young
