Power Factor Correction: alimentatori con PFC attivo o passivo
The main objective of PFC technology is to manage the power used, thus improving the efficiency of the power supply. There are two macro categories of PFC: active or passive, the difference between the two systems being in the structure of the circuit and the electrical components.
Power supplies with active PFC are mainly used within advanced electronic circuits that need to ensure correct power distribution to connected devices. It is the most advanced and precise technology to date.
In contrast, power supplies with passive PFC use inductors and capacitors in series to correct and improve power distribution. This is a cheaper and simpler solution, useful in systems that do not require high precision.
What are the advantages of PFC industrial power supplies?
An industrial power supply system with power factor correction brings with it a large number of positive aspects:
- greater overall stability of the entire system with a reduction in voltage drops;
- increased energy efficiency and consequent savings in energy management costs;
