The Electronic Components Division of BI Technologies (Fullerton, CA), a subsidiary of TT electronics plc (Patterson, NJ), has developed a power-factor corrector (PFC) Evaluation Board, providing a means to add a comprehensive PFC front-end to any power supply design.
The new PFC evaluation board is said to contain all of the necessary control and power circuitry, along with the required inductor assembled onto a compact board. Capable of handling up to 3 kW of power with a proper heatsink, the ready-to-run board accepts 85 Vrms to 265 Vrms input voltage at 50 Hz to 60 Hz.
The PFC evaluation board incorporates BI Technologies' 7720 Series PFC module, which consolidates the required input bridge rectifier, high-speed/low-resistance FET, ultra-high-speed diode, and an over-temperature detector into a single component. The module's design reduces costs associated with a heatsink, provides space reduction, saves assembly time, and eliminates inventory and incoming inspection issues associated with the many components it replaces.
