Fixed compensation
This arrangement uses one or more capacitor(s) to provide a constant level of compensation.
Control may be:
• Manual: by circuit-breaker or load-break switch
• Semi-automatic: by contactor
• Direct connection to an appliance and switched with it.
[Schneider Electric]Нерегулируемая компенсация
В схеме используется один или несколько конденсаторов, обеспечивающих постоянный уровень компенсации.
Управление может быть:
● ручным: с помощью автоматического выключателя или выключателя нагрузки;
● полуавтоматическим: с помощью контактора;
● без управления: прямое подсоединение к нагрузке и включение/отключение вместе с ней.

2 виды коррекции коэффициента мощности
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.
