PWMSignals
PWMSignals refer to pulse-width modulated electrical signals used to regulate power delivery to a load. A PWM signal consists of a train of on/off pulses whose widths vary over time. The two defining parameters are the duty cycle, the fraction of each period that the signal remains high, and the switching frequency, how often the period repeats. The average voltage seen by a suitably filtered load is proportional to the duty cycle (for a fixed input voltage).
Generation and variants. PWM signals are produced by controllers in microcontrollers, dedicated PWM chips, or digital
Applications. PWMSignals are widely used to control motor speed and torque, regulate power supplies, and enhance
Considerations. Higher switching frequencies reduce output ripple but increase switching losses and electromagnetic interference. Lower frequencies
