Through the logic drive circuit, pulse width modulation circuit, zero point detection circuit and power factor detection circuit, the on-off of the self-turning off device in the switch circuit was controlled to control the charging and discharging voltage of the compensation capacitor, and then the capacitor compensation current was controlled.
The power factor automatic compensation control device of the self-turning off device manufactured by this method has the characteristics of simple structure, small volume and high efficiency, and can automatically carry out random power factor compensation for the electric load on site.
Mounting is done with a stud at the bottom of the capacitor. Alpican is designed and made for long life and low losses during the operation. Thus making it one of the most energy eficient capacitors. Non-PCB semi-dry resin reduces the risks of leaking.
The PowerLogic™ PFC Smart Capacitor Bank Detuned automatic capacitor banks provide power factor correction in electrical distribution networks with moderate levels of harmonic content. The series capacitor and reactor combination is tuned below the first dominant harmonic order (usually the 5th).

Low Drop-Out Voltage Regulators: Capacitor-less Architecture …
(DOI: 10.1109/MCAS.2014.2314263) Demand for system-on-chip solutions has increased the interest in low drop-out (LDO) voltage regulators which do not require a bulky off-chip capacitor to achieve stability, also called capacitor-less LDO (CL-LDO) regulators. Several architectures have been proposed; however comparing these reported architectures proves difficult, as each has …
