Højt integreret DC/DC konverter booster effekten fra solcellepaneler med 30 procent
Maxim introducerer 'cell-string optimizer' teknologi, der gør muligt at høste markant mere energi fra solcellepaneler (in english).
New cell-string optimizer technology from Maxim Integrated Products, allows photovoltaic (PV) panels to harvest significantly more energy and simplifies design complexity for solar installation projects.Maxim’s cell-string optimizers are highly integrated DC-DC converters that replace the bypass diode and perform maximum power point tracking (MPPT) deep inside the PV module. By replacing each diode with a MPPT device, the on-off response to performance mismatch is eliminated; every cell-string contributes maximum power without interfering with the power production capability of others.
This enhanced degree of flexibility leads to increased energy production; eliminating collateral performance loss due to module mismatch, degradation, soiling, localized shading, and row shading loss mechanisms.
Based on the company’s industry leading power semiconductor technology, Maxim’s cell-string optimizer is the first integrated power IC to perform MPPT and first to be embedded within the PV module.
- The granularity of Maxim’s cell-string optimizers offers best-in-class shade mitigation, enables flexible system design without adding complexity, and helps improve panel lifetime performance, says Seth Kahn, Executive Director, Solar Products, Maxim Integrated.
- Major PV module companies have recognized the advantages of this unique technology—the first integrated power semiconductor for MPPT—and are ramping it in volume production.
Key advantages include:
• Increases energy harvest: Offers best-in-class shade mitigation, providing 30% additional power over diodes
• Extends reliability: Eliminates hotspots and minimizes the impact of power degradation mechanisms
• Enables lexible design: Higher degree of flexibility to incorporate multiple string lengths, multiple orientations, and expanding modules into partially shaded areas
• Simplifies operation: Fully integrated solution simplifies design by requiring no additional hardware, specialized inverters, or data services
