Enter the ripple current, frequency, and capacitance into the calculator to determine the capacitor ripple voltage. This calculator helps in designing power supplies and electronic circuits that require stable voltage levels.
Capacitor Ripple Voltage Formula
The following formula is used to calculate the capacitor ripple voltage:
Vr = I / (2 * π * f * C)
Variables:
- Vr is the ripple voltage (V)
- I is the ripple current (A)
- f is the frequency (Hz)
- C is the capacitance (F)
To calculate the capacitor ripple voltage, divide the ripple current by the product of 2, π, frequency, and capacitance.
What is Capacitor Ripple Voltage?
Capacitor ripple voltage is the variation in voltage found across the terminals of a capacitor due to the charging and discharging cycles in an alternating current (AC) circuit. It is an important parameter in the design of power supplies, as excessive ripple voltage can lead to instability in electronic circuits and can affect the performance of the components connected to the power supply.
How to Calculate Capacitor Ripple Voltage?
The following steps outline how to calculate the Capacitor Ripple Voltage.
- First, determine the ripple current (I) in amperes (A).
- Next, determine the frequency (f) in hertz (Hz).
- Next, determine the capacitance (C) in farads (F).
- Next, gather the formula from above = Vr = I / (2 * π * f * C).
- Finally, calculate the Capacitor Ripple Voltage (Vr) in volts (V).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Ripple current (I) = 0.5 A
Frequency (f) = 120 Hz
Capacitance (C) = 1000 μF (or 0.001 F)
