STEVAL-IPFC01V1

STEVAL-IPFC01V1 is a 3kW interleaved PFC reference design. It is based on the STNRGPF01 digital controller and includes a separate power board, control board and programming board. The STNRGPF01 is a digital configurable ASIC developed by STMicroelectronics, which can drive up to three channels in an interleaved PFC for industrial applications. The STNRGPF01 digital controller on the control board implements mixed signal (analogue/digital) average current mode control in CCM at fixed frequency. The analogue section ensures cycle-by-cycle current regulation, while digital control manages the non-time critical operations.

• Input voltage range from 90 to 265V AC
• Line frequency range from 47 to 63Hz
• Maximum output power is 3kW at 230V and output voltage is 400V
• Power factor greater than 0.98 at 20% load
• Total Harmonic distortion less than 5% at 20% load
• 111kHz switching frequency, cycle-by-cycle regulation (analogue current control loop)
• Phase shedding, burst-mode operation
• Overvoltage protection, thermal protection and status indicator LEDs
• Inrush current limiter function
• Cooling function
