This video discusses PWM—pulse-width modulation—and two different architectures to implement PWM control for controlling the speed of a BLDC motor. PWM is a square wave signal that repeats itself at a certain frequency. Each PWM cycle is called a period, and the percentage of time the PWM signal is on during a given period determines the duty cycle. With PWM, we’re able to adjust a constant DC voltage to different voltage levels. This helps us control a motor at varying speeds. The video demonstrates two common architectures for PWM control. In the first one, we use a buck converter along with a PWM generator to step down the DC source voltage to the three-phase inverter. In the second one, we discuss a different architecture where the three-phase voltages are modulated directly using PWM control.
