Product details

Overview

STEVAL-ISV002V1 from STMicroelectronics is a 3000 W photovoltaic grid-connected converter evaluation board implementing a two-stage DC-DC + DC-AC architecture with high-frequency isolation, 200–400 V DC input, 450 V DC bus, and 230 V_rms/50 Hz AC output. It integrates MPPT control, LCL-filtered grid synchronization, and digital power management on an STM32F103ZET6 microcontroller.

For engineers reviewing the STEVAL-ISV002V1 datasheet, STEVAL-ISV002V1 pinout, STEVAL-ISV002V1 application, or STEVAL-ISV002V1 equivalent, this board serves as a reference design for utility-scale solar inverters requiring THD < 5%, power factor > 0.9 at full load, and decoupled active/reactive power control in grid-tied PV systems.

Technical Context

The system employs a dual-converter topology: a 35 kHz isolated DC-DC stage using transformer-coupled forward converters with STGW35HF60WD IGBTs, followed by a 17 kHz DC-AC inverter driving an LCL filter to meet EN 50160 grid compliance. Control is fully digital via the STM32F103ZET6, executing real-time MPPT, phase-locked loop (PLL), and PWM modulation with dead-time compensation.

Input sensing includes LEM LV25-P voltage/current transducers and TS954IPT op-amp signal conditioning; output protection uses TD350 gate drivers with DESAT detection and HCPL-4506 optocouplers for galvanic isolation. The board supports BNC-accessible analog signals (grid voltage/current) and jumper-configurable PWM outputs for external validation.

Key Specifications

Parameter	Value and Actual Design Meaning
Nominal Output Power	3 kW - rated continuous grid-tied power delivery under 230 V_rms ±20%, 50 Hz conditions
DC Input Range	200 V to 400 V - compatible with standard PV string configurations without intermediate boost stages
DC Bus Voltage	450 V - optimized for low-loss IGBT switching and minimized capacitor RMS current in DC-AC stage
AC Output	230 V_rms, 50 Hz - meets European single-phase grid interconnection requirements
THD @ Full Load	< 5% - achieved via LCL filter and precise 17 kHz PWM timing, compliant with IEEE 1547/EN 61000-3-12
Power Factor	> 0.9 at rated power - enabled by synchronous current control and reactive power regulation
MPPT Algorithm	Implemented on STM32F103ZET6 - enables dynamic tracking of PV array maximum power point under variable irradiance/temperature

FAQ

What is the primary function of the STEVAL-ISV002V1 board?

The STEVAL-ISV002V1 is a complete 3 kW photovoltaic grid-connected inverter demonstration platform. It performs DC-DC conversion (200–400 V to 450 V) followed by DC-AC inversion (450 V to 230 V_rms/50 Hz), with integrated MPPT, grid synchronization, and LCL-filtered output-all controlled by an STM32F103ZET6 microcontroller.

Does STEVAL-ISV002V1 include firmware, and is source code available?

Yes-the board ships with preloaded firmware implementing MPPT, PLL-based grid synchronization, and dual-stage PWM control. ST provides the full source code (C/C++ for STM32 Standard Peripheral Library) and project files in the associated UM0927 user manual, enabling modification and algorithm validation.

Can STEVAL-ISV002V1 operate in islanding mode or off-grid applications?

No-it is designed exclusively for grid-connected operation. The control firmware relies on grid voltage zero-crossing detection and PLL locking; it lacks anti-islanding protection logic or standalone voltage/frequency regulation required for off-grid use.

What safety certifications does STEVAL-ISV002V1 comply with?

The board implements design practices aligned with IEC 62109 (safety of power converters for PV systems) and EN 61000-3-12 (harmonic limits). While not itself certified as a final product, its topology, layout, and component selection follow requirements for Class A industrial equipment per EN 55011 and grid-code-compliant THD < 5%.
