3 kW three-channel interleaved PFC evaluation kit based on STNRGPF01




The EVAL-IPFC01V1 is a 3 kW interleaved PFC board kit based on the STNRGPF01 three-channel interleaved CCM PFC digital controller. The kit is composed of the following three boards:

STEVAL-IPFC01P1 (power board)

STEVAL-IPFC01C1 (control board)

STEVAL-IPFC01A1 (adapter board)

These boards are sold only as part of the EVAL-IPFC01V1 kit, and cannot be ordered separately.

The STNRGPF01 is a digital configurable ASIC developed by STMicroelectronics, capable of driving up to three channels as interleaved PFC for industrial applications in order to meet IEC 61000-3-2 standards for electrical equipment.

The STNRGPF01 device implements mixed-signal (analog/digital) average current mode control in CCM at fixed frequency. The analog section ensures cycle-by-cycle current regulation while the digital section manages the loop and supervises the operations, giving the power stage adequate flexibility. The STNRGPF01 can be customized for specific applications using eDesign Suite, a dedicated software tool. For complete information on the STNRGPF01, please refer to the device datasheet.
