| Mar 17, 2021 at 11:25 | comment | added | Kartman | The pwm forms an 'average' voltage - ie 50% duty cycle = 50% of bus voltage, 10% duty cycle = 10% bus voltage and so on. The duty cycle is varied by a sine table to approximate a sine wave. The inductance of the windings also serves as a low pass filter so whilst the pwm signal is on/off, the actual current is smoothed by the inductance. | |
