Product details
Overview
STEVAL-ISV003V1 from STMicroelectronics is a 250 W plug-in photovoltaic microinverter demonstration board implementing grid-synchronized DC-AC conversion with MPPT, reactive power management, and digital control via STM32F103ZET6 MCU. It accepts 20–40 V DC input, delivers 230 V AC / 50 Hz output, and features RS-232 communication and LED-based user interface for parameter monitoring.
For engineers reviewing the STEVAL-ISV003V1 datasheet, STEVAL-ISV003V1 pinout, STEVAL-ISV003V1 application, or STEVAL-ISV003V1 equivalent, this board serves as a validated reference for solar panel-level DC-AC conversion, grid-tie algorithm validation, MPPT implementation using perturb-and-observe, and high-frequency isolated boost + full-bridge inverter topology evaluation.
Technical Context
The board implements a two-stage power architecture: an interleaved high-frequency isolated DC-DC boost converter (stepping PV voltage to ~400 V) followed by a full-bridge DC-AC inverter. Control is fully digital, executed by the STM32F103ZET6, which runs decoupled active/reactive power regulation algorithms and real-time MPPT.
Grid synchronization uses sinusoidal voltage feedback in closed-loop mode, while open-loop operation relies on internal lookup-table-generated references. Sensing includes PV voltage/current, AC line voltage/current, and output AC filtering - all conditioned through precision op-amps (TSV992, TS912) and isolated gate drivers (L6390, HCPL-4506).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 20 V to 40 V DC - matches typical single-panel PV string output under partial shading or low irradiance. |
| Output Voltage/Frequency | 230 V AC, 50 Hz - compliant with European and many global residential grid standards. |
| Rated Power | 250 W - optimized for individual commercial/residential solar panels (e.g., 250–300 Wp modules). |
| MPPT Algorithm | Perturb-and-Observe (P&O) - implemented in STM32 firmware for real-time tracking without external sensors beyond panel voltage/current. |
| Control MCU | STM32F103ZET6 - 32-bit ARM Cortex-M3 with 512 KB Flash, 64 KB RAM, multiple timers, ADCs, and PWM peripherals dedicated to inverter control loops. |
| Communication Interface | RS-232 - enables serial telemetry of measured voltage, current, and operating status for lab validation and firmware debugging. |
| Isolation Architecture | HF transformer-based DC-DC + optocoupled gate drives (HCPL-4506) - ensures safety-critical galvanic separation between PV side and grid side. |

FAQ
What is the primary function of the STEVAL-ISV003V1?
The STEVAL-ISV003V1 is a complete 250 W microinverter demonstration board designed to convert DC power from a single photovoltaic panel into grid-compliant 230 V AC / 50 Hz output. It integrates MPPT, grid synchronization, reactive power control, and digital supervision via the STM32F103ZET6, enabling rapid validation of panel-level inverter topologies and control firmware.
Does the board support both open-loop and closed-loop grid synchronization?
Yes - the board supports dual operation modes. In closed-loop mode, it uses sinusoidal voltage feedback proportional to the grid voltage for precise phase alignment. In open-loop mode, it generates the reference waveform internally via a lookup table, allowing standalone testing without grid connection.
Which ST components are central to its power stage and control architecture?
The power stage relies on ST's L6390 high-voltage gate drivers, PM8834 half-bridge drivers, STPS3L60U Schottky diodes, and STTH108 fast recovery diodes. The control core is the STM32F103ZET6 MCU, supported by TSV992/TS912 precision op-amps for sensing and HCPL-4506 optocouplers for isolation-critical signal transmission.
Can the STEVAL-ISV003V1 be used with 60 Hz grids?
No - the STEVAL-ISV003V1 is specifically configured for 50 Hz grid operation. ST offers the companion board STEVAL-ISV003V2, which is hardware- and firmware-optimized for 60 Hz networks, including adjusted timing parameters and filter component values for North American and Japanese grid standards.
