About PWM to Voltage Calculator (Formula)

A PWM to Voltage Calculator is a tool used to convert a Pulse Width Modulation (PWM) signal into a corresponding analog voltage level. This conversion is commonly used in electronics and control systems to translate digital PWM signals into analog signals that can control various devices or components. The formula for this conversion is as follows:

Voltage Output (Vout) = (Duty Cycle / 100) × Voltage Reference

Where:

  • Voltage Output (Vout): The analog voltage output obtained from the PWM signal.
  • Duty Cycle: The percentage of time the PWM signal is in the “on” state during one cycle.
  • Voltage Reference: The maximum voltage level that the PWM signal is intended to represent.

In this formula, the duty cycle represents the fraction of time the PWM signal is high (on) during one complete cycle. By scaling the duty cycle with the voltage reference, you can obtain the corresponding analog voltage output. This analog voltage can then be used to control various devices, such as motors, LEDs, or sensors.
