STMicroelectronics STEVAL-ISF002V1

Overview

STEVAL-ISF002V1 from STMicroelectronics is a 1.4 kW digital power factor correction (PFC) demonstration board built around the STW23NM60N MDmesh™ MOSFET, TD352 gate driver, and STM32F103ZE microcontroller. It delivers 415 VDC output at ≤5% ripple, achieves PF up to 0.998, and supports real-time PI tuning via embedded UI - enabling evaluation of high-performance digital PFC in industrial AC-DC front-end designs.

For engineers reviewing the STEVAL-ISF002V1 datasheet, STEVAL-ISF002V1 pinout, STEVAL-ISF002V1 application, or STEVAL-ISF002V1 equivalent, this board serves as a validated reference for digital PFC implementation, dual FOC motor control integration, hardware/software protection schemes, and MCU-based power conversion system development.

Technical Context

The board implements continuous-conduction mode (CCM) digital PFC using the STM32F103ZE's ADC, PWM, and timer peripherals to execute real-time current/voltage loop control. The STW23NM60N (600 V, 23 A, R_DS(on) = 0.22 Ω) handles main switching, while the TD352 provides isolated high-side gate drive with desaturation detection and soft shutdown.

Input rectification uses an 8 A/400 V bridge (D1); output filtering employs two 330 µF/450 V electrolytics (C6, C7). An off-line SMPS based on VIPer12A-E supplies 15 V for drivers and 5 V for control logic. The MC connector enables interoperability with ST's motor control boards for integrated PFC + inverter systems.

FAQ

Is STEVAL-ISF002V1 still in production?

No - STEVAL-ISF002V1 is marked obsolete per ST's official documentation (Doc ID 17282 Rev 1, April 2010). It remains available through authorized distributors and Aetrix Electronics for legacy design support, reference reuse, and educational evaluation, but no new revisions or long-term production commitments exist.

Can this board be used with other STM32 MCUs?

The board is specifically designed for the STM32F103ZE (LQFP144, 512 KB Flash, 64 KB RAM) and relies on its ADC timing, PWM dead-time control, and GPIO mapping. While firmware porting to compatible F1-series MCUs is possible, pin compatibility, peripheral clocking, and interrupt latency must be verified - no drop-in substitution is supported.

What motor control capabilities does it demonstrate?

It supports dual Field-Oriented Control (FOC) motor drive demonstration via the MC connector, providing synchronized PFC bus voltage and phase current sensing signals (A/B/C), encoder inputs (A/B/Index), and gate drive outputs (UH/UL/VH/VL/WH/WL) - enabling full-system validation of PFC-fed inverter topologies.

Does it include safety certifications?

No - STEVAL-ISF002V1 is a demonstration board intended for lab evaluation only. It lacks UL/IEC/EN safety certification, reinforced isolation, or enclosure compliance. Users must implement appropriate isolation, grounding, and protective enclosures before integration into certified end equipment.
