Peak Voltage Calculator:
Enter the value of average voltage, Vave(V) to determine the value of Peak Voltage, Vp(V).
Peak Voltage Formula:
Peak Voltage (Vp) refers to the maximum voltage reached by an alternating current (AC) waveform during one cycle. It is a critical parameter in electrical systems, helping determine the limits of electrical components and insulation. AC waveforms, such as sine waves, alternate between positive and negative peak voltages. The peak voltage is measured from the zero baseline to the maximum positive or negative amplitude.
It is derived from the average voltage using a mathematical relationship specific to sinusoidal waveforms. Vave(V) is the average of all instantaneous voltage values over a half-cycle, while Vp(V) represents the amplitude of the wave.
This relationship assumes a pure sine wave and does not account for waveform distortions or harmonics. Peak voltage calculations are crucial in designing power supplies, amplifiers, and other AC-dependent systems. By knowing Vp(V), the RMS voltage and other parameters can also be determined.
Peak Voltage, Vp(V) in volts equals the average voltage, Vave(V) in volts, multiplied by pi divided by 2.
Peak Voltage, Vp(V) = Vave(V) * 3.14 / 2
Vp(V) = peak voltage in volts, V.
Vave(V) = average voltage in volts, V.
Peak Voltage Calculation:
1.A sinusoidal AC waveform has an average voltage of 10V. Calculate the peak voltage.
Given: Vave(V) = 10V.
Peak Voltage, Vp(V) = Vave(V) * 3.14 / 2
Vp(V) = 10 * 3.14 / 2
Vp(V) = 10 * 1.5708
Vp(V) = 15.708V.
2.The peak voltage of an AC waveform is 20V. Calculate the average voltage.
Given: Vp(V) = 20V.
Peak Voltage, Vp(V) = Vave(V) * 3.14 / 2
Vave(V) = Vp(V) / 3.14 / 2
Vave(V) = 20 / 3.14 / 2
Vave(V) = 12.73V.
