Some computer and other power supply boxes have a feature called PFC (power factor correction, also known as power factor controller), which lowers the amount of reactive power produced by a computer.
In opposition to genuine power, reactive power energizes the magnetic field. By enhancing power factor, power factor correction (PFC) technology lowers energy use and expenses.
This maximizes the amount of real power drawn from the grid supply, lowering energy costs and inefficiency while minimizing the chance that the supplier would charge for reactive power.
The global power factor correction (PFC)controllers market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The latest mixed-signal controller for the bridgeless totem pole PFC (TP PFC) topology was unveiled by onsemi, a pioneer in intelligent power and sensor technology.
The NCP1681 aims to power offline power supply with extremely high density. The NCP1680, which is suitable for designs up to 350 W, has been a success, and the new controller expands the power potential into the kilowatt range.
In the past, TP PFC designs had to incorporate an MCU, which increased design complexity and demanded coding. To create a fully functional TP PFC solution using the NCP1681, however, only a few external parts and no coding are required, which saves time, money, and space.
The NCP1681 can be set up to operate in either fixed frequency continuous conduction mode (CCM) or multi-mode operation, where the controller automatically switches between CCM and critical conduction mode (CrM) for the best performance over a range of power levels.
The new NCP1681 high power PFC controller combines cutting-edge capabilities with well-proven control algorithms to produce a high-performance and reasonably priced TP PFC solution. It is also possible to meet demanding efficiency requirements like “80Plus” or “CoC Tier 2,” which demand great efficiency over a wide load range.
