Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Peak voltage (V)

Required number input.

Calculate the average rectified voltage of a sinusoid from its peak voltage. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Average rectified voltage (V)

The resulting average rectified voltage returned as a number.

• Compact electronics formulas omit some combination of tolerances, temperature drift, bandwidth, loading, parasitics, noise spectrum, nonlinearity, clipping, calibration, layout, and device-specific limits. Typical datasheet values are not guaranteed limits.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Form Factor

  Calculate the form factor of a sinusoid as RMS voltage divided by average rectified voltage.

• Peak From RMS

  Calculate the peak current of a sinusoid from its RMS current.

• RMS From Peak

  Calculate the RMS current of a sinusoid from its peak current.
