Product details
Overview
STEVAL-ISV008V1 from STMicroelectronics is a 300 W photovoltaic (PV) converter demonstration board integrating three SPV1020 monolithic DC-DC boost converters on a single PCB, supporting distributed PV panel architectures with three isolated strings. It operates across 0–40 V input, delivers up to 98% peak efficiency, implements Perturb & Observe MPPT with 0.2% duty-cycle resolution, and includes overvoltage, overcurrent, and overtemperature protection.
For engineers reviewing the STEVAL-ISV008V1 datasheet, STEVAL-ISV008V1 pinout, STEVAL-ISV008V1 application, or STEVAL-ISV008V1 equivalent, this board serves as a validated reference for distributed MPPT in residential and commercial solar string optimization, parallel-output PV module integration, and high-reliability DC-DC conversion without electrolytic capacitors.
Technical Context
The board implements a 4-phase interleaved synchronous boost topology using three SPV1020 ICs, each embedding power MOSFETs and running a dedicated MPPT algorithm. Fixed 100 kHz switching frequency (externally adjustable) enables precise duty-cycle control from 5% to 90% with 0.2% resolution.
It supports automatic burst-mode transition at low irradiance to maintain efficiency, built-in soft-start prevents inrush, and output configuration is fixed to parallel connection per design-no series output allowed on this board variant. Safety logic halts drivers during overvoltage or overtemperature events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0–40 V: Supports full operational range of standard silicon PV modules under varying irradiance and temperature. |
| Peak Efficiency | Up to 98%: Minimizes thermal loss and enables compact thermal design in enclosed PV junction boxes. |
| MPPT Accuracy | 0.2% duty-cycle resolution: Enables fine-grained tracking of MPP drift due to partial shading or temperature gradients. |
| Switching Frequency | 100 kHz (adjustable): Balances EMI control, magnetics size, and conduction losses in distributed PV applications. |
| Protection Features | Overvoltage, overcurrent, overtemperature: Hardware-level shutdown ensures compliance with IEC 62109 and UL 1741 safety requirements. |
| Topology | 4-phase interleaved synchronous boost: Eliminates need for bulk electrolytic capacitors, extending lifetime beyond 25 years. |

FAQ
What is the maximum input voltage supported by STEVAL-ISV008V1?
The board accepts up to 40 V DC input per SPV1020 channel, aligning with the open-circuit voltage of typical 12-V nominal PV modules under cold, high-irradiance conditions. This rating is verified per the SPV1020 datasheet absolute maximum ratings and confirmed in the STEVAL-ISV008V1 schematic and layout constraints.
Can the outputs be configured in series instead of parallel?
No-STEVAL-ISV008V1 is hardwired for parallel output only, as explicitly stated in the data brief: "For the STEVAL-ISV008v1 only the output parallel connection is allowed." Series connection would require board-level redesign and is not supported by default layout or firmware.
Does the board include onboard MPPT firmware, or is external host control required?
The MPPT algorithm runs autonomously within each SPV1020 IC using embedded logic; no external processor or firmware upload is needed. The SPI interface allows optional monitoring or parameter adjustment but is not required for basic MPPT operation.
Is STEVAL-ISV008V1 RoHS compliant and certified for PV system use?
Yes-the board is RoHS compliant per the data brief, and its constituent SPV1020 ICs meet IEC 62109-1/2 for PV inverters. While the board itself is not a certified end-product, it is designed and tested to support certification-ready system integration in Class II PV applications.
