PWM to Voltage Converter

Convert PWM duty cycle to average DC voltage and vice-versa. Ideal for microcontroller signal processing.

PWM Parameters

Peak Voltage (Vₚₖ) [V]

Duty Cycle (%)50%

Find Duty Cycle for Target Voltage (V)

Pulse Width Modulation (PWM) creates an average DC voltage by rapidly switching a signal between 0V and peak voltage. The average voltage is directly proportional to the duty cycle.

Conversion Results

Average Voltage (Vₐᵥ)

2.500 V

Required Duty for 2.5V

50.00%

Microcontroller Tip

If your MCU has an 8-bit PWM, multiply the percentage by 2.55 to get the register value (0-255). For 10-bit, multiply by 10.23 (0-1023).
