Capacitor Selection Voltage Regulator Design | DigiKey
Choose ceramic capacitors with a voltage rating of at least 1.5 times the maximum-input voltage. If tantalum capacitors are selected, they should be chosen with a voltage rating of at least twice the maximum-input voltage. A small ceramic capacitor in parallel to the bulk capacitor is recommended for high-frequency decoupling. The L-C …

The shunt capacitor helps balance power transmission issues such as low voltage regulation, poor reliability, and power factors. Moreover, it can divide into HV capacitor and LV capacitor. How Does a Shunt …
Calculating the capacitor values to control ceiling fan speed
I have an old ceiling fan motor that runs with a 1.5µF run capacitor, at what I believe is, its full intended speed. With the help of some folks here at StackExchange I''ve wired everything up as in the image below, also refer to the schematic further down this question.
Understanding the Critical Roles of Specialty Capacitors in Power ...
Their ability to store electric charge makes them essential components for regulating and smoothing power flow. Many of these capacitors are standard fare, but a few play highly specialized, functional roles. To meet application-specific demands, these capacitors must be selected carefully based on function, size, and interoperability.
Capacitor Bank
An automatic capacitor bank is a device that, after detecting the presence of inductive reactive energy above the desired value in an electrical installation, acts by automatically connecting capacitor groups (steps) necessary to adapt to the demand and keeps the PF roughly constant (IEC 61921, 2017).

Varying run capacitor for speed control of single phase motor
Changing the capacitor value changes the amplitude and phase shift of the current in the auxiliary winding. Reducing the capacitor value lowers the torque values of the torque vs. speed curve as shown below. This method of speed control is often used for fans, because the torque requirement of a fan is lower at lower speed.
