RECOM’s PFC front-ends provide a high-performance primary stage for advanced AC/DC power architectures. These modules are engineered with advanced active PFC stages to deliver a power factor of >0.95, ensuring full compliance with international harmonics regulations such as EN61000-3-2. By utilizing these specialized power factor correction stages to convert single-phase or three-phase AC input into a stabilized high-voltage DC bus, these units function as a robust interface for downstream isolated DC/DC converters.
Engineered for industrial, e-mobility, and railway infrastructure, our PFC front-end units are available in open-frame, chassis-mount, and 19-inch rack formats. These non-isolated PFC power stages are designed for maximum power density, allowing engineers to build scalable systems up to 4kW with minimal grid interference. Choosing RECOM ensures a reliable, pre-certified solution that simplifies the path to meeting stringent power quality requirements in high-power applications.

Frequently Asked Questions
A PFC front-end serves as the initial stage of an AC/DC power chain. It utilizes active PFC stages to align input current with voltage, reducing harmonic distortion and maximizing the real power available from the AC grid.
Typically, PFC front-end units are non-isolated. They are designed to provide a regulated DC bus to feed secondary isolated DC/DC converters. This modular architecture using dedicated PFC stages allows for higher efficiency and smaller footprints in high-power systems.
Standards like EN61000-3-2 mandate low harmonic signatures for equipment over 75W. An active power factor correction stage prevents the spiky current draw of traditional rectifiers, protecting the grid and preventing the nuisance tripping of circuit breakers.
Yes. Our portfolio includes specialized 3-phase PFC stages designed for balanced load distribution across all phases, which is essential for heavy industrial machinery and high-speed EV charging stations.
