Hello, I've got a sensorless BLDC motor control application on a DSP56F805. I'm sampling the entire ADC bank, including phase currents and voltages, at the trough of the PWM carrier (center aligned PWM) in order to measure average current. I'm using a minimum-ripple PWM scheme in which the top switch turns off and the current circulates around GND for part of the PWM cycle. For better ...
