An electronic circuit called a multi-mode PFC (Power Factor Correction) controller is made to regulate the power factor of an AC-DC power supply. A load’s efficiency in utilising electrical power is determined by the power factor. When the power factor is high, the load is effectively using the electricity, and when it is low, there is a lot of energy being lost.
A PFC controller operates by adjusting the power supply’s input current so that it is in phase with the input voltage. As a result, the power supply becomes more efficient and has a high power factor.
A multi-mode PFC controller can function in several modes according to the demands of the load. Depending on the load conditions, it might work in either a continuous conduction mode (CCM) or a discontinuous conduction mode (DCM). This enables the controller to optimise the power factor for various loads, leading to greater efficiency all around.
To ensure the safe and dependable operation of the power supply, a multi-mode PFC controller may additionally have additional functions like overvoltage protection, overcurrent protection, and thermal protection.
Global multi-mode PFC controller market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The HR1210 and HR1211, multi-mode PFC and current mode LLC combination controllers that can be programmed via a UART interface, have been introduced by Monolithic Power Systems, Inc. (MPS).
The HR1210 uses a proprietary digital average current control method to accomplish hybrid CCM and DCM operation, while the HR1211 has three operation modes that are implemented based on various load conditions to achieve optimal efficiency across the complete operating range[1][2].
Moreover, MPS provides the MP44019 CrM/DCM Multi-Mode PFC Controllers, which lower switching frequency by utilising dead time extension technology under mild loads.
The IDP2308 Digital Multi-Mode PFC + LLC Combo Controller from Infineon Technologies combines a starting cell and a floating high side driver.
Advanced algorithms are provided by a digital engine. An revolutionary multimode power factor controller from Onsemi, the NCP1655, automatically switches from Continuous Conduction Mode (CCM) to Critical Conduction Mode (CrCM) depending on the load requirements.
