67 PFC types
виды коррекции коэффициента мощности
-There are 2 types of power factor correction: fixed or automatic.
Fixed power factor correction consists of inserting, in parallel on the network, a capacitor bank whose total power is provided by the assembly of capacitors of identical or different ratings. The bank is energized by a contactor that simultaneously supplies all the capacitors (a single step).
The inrush current peak, in the case of fixed correction, can reach 30 times the nominal current of the capacitor bank.
An automatic power factor correction system, on the other hand, consists of several capacitor banks of identical or different ratings (several steps), energized separately according to the value of the power factor to be corrected.
An electronic device automatically determines the power of the steps to be energized and activates the relevant contactors.
The inrush current peak, in the case of automatic correction, depends on the power of the steps already on duty, and can reach 100 times the nominal current of the step to be energized.

PFC Types
There are two types of Power Factor Correction - Passive PFC and Active PFC.
Passive PFC uses passive elements like a ferrite core inductor on the AC input. It is very easy to implement in existing power circuits although the power factor is low at 60-80%. The proper AC input voltage (115V or 230V) must also be chosen manually. In addition, significant EMI can still result with a 115V AC source. Of course, a 230V AC source will not have this problem!.
Active PFC, on the other hand, uses a switching regulator with active elements like an IC, FETs (Field Effect Transistors) and diodes to create an active PFC circuit. This circuit allows the power supply to achieve a power factor of up to 95%, significantly reduce harmonics and automatically adjusts the AC input voltage. This means you do not have to manually select the AC input voltage. It works with all voltages from 110V to 240V.

69 Brush, Charles Francis
[br]b. 17 March 1849 Euclid, Michigan, USAd. 15 June 1929 Cleveland, Ohio, USA[br]American engineer, inventor of a multiple electric arc lighting system and founder of the Brush Electric Company.[br]Brush graduated from the University of Michigan in 1869 and worked for several years as a chemist. Believing that electric arc lighting would be commercially successful if the equipment could be improved, he completed his first dynamo in 1875 and a simplified arc lamp. His original system operated a maximum of four lights, each on a separate circuit, from one dynamo. Brush envisaged a wider market for his product and by 1879 had available on arc lighting system principally intended for street and other outdoor illumination. He designed a dynamo that generated a high voltage and which, with a carbon-pile regulator, provided an almost constant current permitting the use of up to forty lamps on one circuit. He also improved arc lamps by incorporating a slipping-clutch regulating mechanism and automatic means of bringing into use a second set of carbons, thereby doubling the period between replacements.Brush's multiple electric arc lighting system was first demonstrated in Cleveland and by 1880 had been adopted in a number of American cities, including New York, Boston and Philadelphia. It was also employed in many European towns until incandescent lamps, for which the Brush dynamo was unsuitable, came into use. To market his apparatus, Brush promoted local lighting companies and thereby secured local capital.[br]Principal Honours and DistinctionsChevalier de la Légion d'honneur 1881.
