Averaging voltage. Find the average value of a signal over a time interval/one full cycle: Vavg = (1/T) ∫ V(t) dt. In the case of sinuoidal AC, full-wave rectified average = 0.637 Vpeak, and half-wave rectified average = 0.318 Vpeak.
Formula & Table Summary:
- General: Vavg = (1/T) ∫0→T V(t) dt
- Half-wave rectified: Vavg = Vpeak/π ≈ 0.318 × Vpeak
- Full-wave rectified: Vavg = 2Vpeak/π ≈ 0.637 × Vpeak
- From RMS (sinusoidal): Vavg = 0.9 × VRMS

Calculator of Average Voltage - Rapid Electrical.
The averaverage voltage calculatorists you in arriving at the mean of a voltage signal per cycle or a period of time. It is widely applied in AC circuits and rectifiers as well as signal analysis to find the effective DC value of an alternating current. It takes a few button presses to calculate the average voltage and makes the circuit behavior more understandable by entering waveform type, peak or RMS values, and time period. Mean voltage is necessary in power electronics, battery charging, and motor control. In the case of sinusoidal waveforms, it is computed by taking the integration over a cycle, whereas in the case of rectified signals, the process is simplified by formulas. This calculator reduces time in that the equations are automated into a simplified result, hence proper design and testing results are obtained.
| Scenario | Inputs | Formula | Result |
|---|---|---|---|
| Half-wave rectified | Vpeak = 100 V | Vavg = 100/π | 31.8 V |
| Full-wave rectified | Vpeak = 100 V | Vavg = 2×100/π | 63.7 V |
| From RMS | VRMS = 70.7 V | Vavg = 0.9 × 70.7 | 63.6 V |
