Capacitor Size for a DC motor. Do I even need one?
So my question is 2-fold. Do I need a capacitor and how would I calculate what size I need? The specs I have available for the motor are 2.25hp, 130V, 12.9A. The max I ever need to use it is maybe 80%, after that it''s almost too fast to be useable. ... If you use a SCR, then also an EMI filter on the input side is needed. Beside this, I would ...
Bypass Capacitor Calculator
Let''s say we want to find out what value of a bypass capacitor that we need if we want to filter out an AC signal of 60Hz with a 500Ω resistor in parallel to the capacitor. Plugging into the formula, C= 1/2πfcXC= 1/2(3.14)(60Hz)(500Ω)= 54μF, rounded up.

Full-wave bridge rectifier with capacitor filter and ripple voltage
The voltage change on a capacitor from a current over time is: dV = A s / F. where: dV is the voltage change A the current in Amperes s the time in seconds F the capacitance in Farads. This pretty much tells you the peak to peak ripple, except that it is in terms of the time for the droop, not the frequency of the signal being rectified.
Harmonic Filter Calculator
A series tuned harmonic filter is a combination of inductor and capacitor designed to trap a certain harmonic. These filters are applied in parallel with the power system and is often called shunt passive filters. For most harmonic filters in power systems, filters are tuned to 4.2 or 4.7 for trapping 5th order harmonics.

3.2: Rectification
For example, filter capacitor size is greatly reduced. There are two popular methods to achieve full-wave rectification. The first method uses a pair of diodes with a center-tapped (i.e., split) secondary. The second method uses a four diode bridge network. The diode bridge form is also capable of producing a bipolar output (i.e., a …

Electronics Principles and Devices Rectifier with Filter
Capacitor Filter A half-wave rectifier with a capacitor-input filter is shown in Figure 2. The filter is simply a capacitor connected from the rectifier output to ground. RL represents the equivalent resistance of a load. We will use the half-wave rectifier to illustrate the basic principle and then expand the concept to full-wave rectification.
How do I decide what capacitor to use in a circuit?
In the circuit you show the regulator will be stable and will work with capacitors from 0 to thousands of uF on the input or the output (a 0.33 electrolytic or 0.1 ceramic or greater on the input is advisable if you''re far from the input filter cap).
