Product details

Overview

STEVAL-IPFC01V1 from STMicroelectronics is a 3 kW three-channel interleaved power factor correction (PFC) reference design based on the STNRGPF01 digital controller, implementing mixed-signal average current mode control in continuous conduction mode (CCM) at 111 kHz. It delivers 400 V DC output from 90–265 VAC input with >0.98 power factor at 20% load and <5% THD under same conditions, targeting industrial AC-DC front-end systems.

For engineers reviewing the STEVAL-IPFC01V1 datasheet, STEVAL-IPFC01V1 pinout, STEVAL-IPFC01V1 application, or STEVAL-IPFC01V1 equivalent, this board supports rapid validation of high-efficiency, digitally controlled interleaved PFC topologies with analog inner-loop bandwidth, phase shedding, burst-mode operation, and integrated thermal/overvoltage protection.

Technical Context

The STEVAL-IPFC01V1 implements a hybrid control architecture: an analog proportional-integral (PI) compensator handles cycle-by-cycle current regulation for maximum bandwidth, while a digital PI controller manages the outer voltage loop with fast dynamic response. The STNRGPF01 ASIC drives three independent boost channels with synchronized PWM generation and real-time feed-forward compensation for input voltage and load variations.

It integrates hardware-based protections including overvoltage lockout, thermal shutdown, and cycle-by-cycle overcurrent detection via dedicated OCP_EN signals. Phase shedding and burst-mode operation are executed autonomously by the digital core to maintain efficiency across 20–100% load range without firmware intervention.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	90–265 VAC: Enables universal mains compatibility across global industrial and commercial AC grids.
Output Power	3 kW at 230 VAC: Supports high-power server PSUs, telecom rectifiers, and industrial motor drives requiring robust front-end PFC.
Output Voltage	400 V DC: Matches standard bus voltage for downstream LLC or phase-shifted full-bridge converters in high-efficiency SMPS designs.
Power Factor	>0.98 at 20% load: Ensures compliance with IEC 61000-3-2 Class C/D harmonic limits even at light loads.
THD	<5% at 20% load: Meets stringent EN 61000-3-2 requirements for nonlinear equipment without external filtering overhead.
Switching Frequency	111 kHz fixed: Balances EMI filter size, MOSFET switching loss, and magnetic component volume in compact 3 kW layouts.
Control Architecture	Mixed-signal CCM: Analog inner current loop guarantees sub-microsecond response; digital outer loop enables adaptive tuning and fault logging.

FAQ

What is the role of the STNRGPF01 ASIC on the STEVAL-IPFC01V1 control board?

The STNRGPF01 is a configurable digital controller that orchestrates three-phase interleaved PFC operation. It generates synchronized PWM signals (PWM0–PWM2), executes digital voltage-loop PI control, manages phase shedding and burst mode, and interfaces with analog current sensing and protection circuits - all while offloading time-critical regulation to dedicated analog hardware.

Does STEVAL-IPFC01V1 include hardware for inrush current limiting and thermal monitoring?

Yes. The power board integrates an NTC-based inrush limiter circuit with relay bypass, and the system monitors temperature via an STLM20W87F analog sensor feeding into the STNRGPF01's ADC channel. Thermal protection triggers automatic shutdown when threshold exceeds programmed limit, with status indicated by onboard LEDs.

Can the STEVAL-IPFC01V1 be reconfigured for different output voltages or power levels?

Yes - using ST's eDesignSuite software, users can retune the STNRGPF01's digital control parameters (voltage reference, PI gains, feed-forward coefficients, OCP thresholds) to adapt the design for 380–420 V outputs or scaled-down 1.5–2.5 kW operation, provided passive components (inductors, capacitors, MOSFETs) meet revised stress requirements.

What interface is used to program and monitor the STNRGPF01 on this board?

Programming and real-time monitoring are performed via the SWIM (Serial Wire Interface Module) debug port on the control board, accessible through the J2 header. ST's SPIM Flash Loader and eDesignSuite tools communicate over this interface to configure registers, read telemetry (I_in, V_out, temperature), and log fault events during validation.
