Product details
Overview
STEVAL-ISV018V1 from STMicroelectronics is a 300 W photovoltaic demonstration board integrating three SPV1020 DC-DC boost converters, each implementing Perturb and Observe MPPT with 0.2% accuracy, operating from 6.5 V to 40 V input and delivering up to 120 V output, designed for distributed PV panel string optimization in rooftop solar systems.
For engineers reviewing the STEVAL-ISV018V1 datasheet, STEVAL-ISV018V1 pinout, STEVAL-ISV018V1 application, or STEVAL-ISV018V1 equivalent, this board enables rapid validation of multi-string PV energy harvesting with series/parallel output configuration, SPI-based telemetry, and burst-mode efficiency enhancement under low irradiance.
Technical Context
The board implements a 4-phase interleaved boost topology using three SPV1020 ICs, each integrating power MOSFETs and synchronous rectification to eliminate external electrolytic capacitors and extend lifetime. Each converter operates at fixed 100 kHz switching frequency (externally tunable) with 5–90% duty cycle resolution of 0.2%.
MPPT logic runs autonomously per channel, enabling local maximum power point tracking independent of temperature and irradiance-eliminating reliance on centralized inverter computation. Protection includes overvoltage, overcurrent, and overtemperature shutdown with built-in soft-start and automatic burst-mode transition below light threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 6.5 V to 40 V - supports wide-range PV string voltages including partial shading conditions |
| Output Voltage | Up to 120 V - enables high-voltage DC bus generation for grid-tied or battery-charging inverters |
| MPPT Accuracy | ±0.2% - ensures precise tracking of true maximum power point across varying irradiance and temperature |
| Peak Efficiency | 98% - minimizes thermal stress and system-level energy loss in distributed PV architectures |
| Switching Frequency | 100 kHz (tunable) - balances EMI control, magnetics size, and conduction losses |
| Duty Cycle Range | 5% to 90% in 0.2% steps - provides fine-grained control for dynamic MPPT response |
| Interface | SPI - enables real-time telemetry (Vin, Vout, Iout, temperature) and remote parameter adjustment |

FAQ
What is the default output configuration of STEVAL-ISV018V1?
The board is configured by default for series connection of the three SPV1020 outputs, enabling higher DC bus voltage generation suitable for grid-tied inverters. Parallel connection is supported via PCB jumper rework and firmware configuration through the SPI interface.
Does STEVAL-ISV018V1 include bypass diode replacement functionality?
Yes - it replaces conventional bypass diodes with active MPPT-enabled boost converters (SPV1020), recovering energy otherwise lost during partial shading and increasing overall panel yield by up to 25% compared to passive diode solutions.
Can the MPPT algorithm be modified or disabled?
No - the Perturb and Observe MPPT is hardwired in the SPV1020 silicon and cannot be disabled or replaced. However, SPI registers allow readback of MPPT status, operating point, and fault flags for system-level monitoring and diagnostics.
What protection features are implemented on the board?
The board inherits full protection from each SPV1020 IC: output overvoltage shutdown, overcurrent limiting with foldback, junction overtemperature shutdown, and soft-start current ramp control - all implemented autonomously without external supervision.
