PFC evaluation board to test power supplies

A power-factor correction evaluation contains all of the necessary control and power circuitry to test power-factor correction modules.

The BI Technologies Electronic Components Division of TT Electronics has brought out a PFC (power-factor correction) evaluation board to provide power-supply engineers with a means to test their circuit designs.

The ready-to-run evaluation board contains all of the necessary control and power circuitry, along with the required inductor assembled onto a compact board, to test power-factor correction modules.

"We developed the evaluation board to make the design process easier for customers", says Mike Ochoa-Hougan, Product Manager for BI Technologies Electronic Components Division.

"The board allows designers to test their circuits to ensure that the module will operate at a specified tolerance".

"If there is a deviation, the evaluation board will detect it".

The PFC evaluation board offers correction to near unity power factor and better than 95% efficiency, allowing it to evaluate accurately a variety of applications, including switching power supplies from 500W to 3kW, motor drives, servo amplifiers, solenoid drivers, solid-state relays and three-phase rectifier bridges.

The evaluation board accepts 85 to 265 V RMS input voltage at 50 to 60Hz, and is capable of handling up to 3kW of power with a cooled heatsink.

BI Technologies also offers a series of PFC modules in three standard configurations.

Designated the 7720 Series, the modules suit power supplies ranging from 500W to 3kW, and are capable of replacing up to ten TO220 or TO247 discrete power semiconductors required to achieve power factor correction in a conventional power supply design.

Pricing for PFC evaluation board is US $199.

Lead time is from stock to 12 weeks.
