A New Standard in Solar System Optimization with GaN Technology

EPC9178 – Compact and Efficient Solar Optimizer

Efficient Power Conversion Corporation (EPC), a leader in gallium nitride (GaN) transistor technology, has introduced an innovative reference design – the EPC9178. This groundbreaking product redefines standards in solar system optimization, offering exceptional energy efficiency, reliability, and cost reduction.

GaN Technology for Higher Efficiency

The EPC9178 is based on eGaN® FETs (EPC2306 models), which outperform traditional silicon-based MOSFETs. Key advantages of this technology include:

• Lower Switching Losses – significant improvement in system efficiency.
• High Operating Frequency (450 kHz) – smaller passive components, contributing to the compactness of the entire system.
• High Reliability – ideal for demanding conditions, such as shaded panels.

Key Features of the EPC9178

• Compact Design: Minimization of size and weight thanks to smaller passive components.
• High Energy Efficiency: Peak efficiency up to 98%, significantly reducing energy losses and improving thermal management.
• Voltage Versatility: Supports input voltages from 30 to 60 V and offers selectable output voltages of 30 V, 45 V, and 60 V.
• Simplified Design: The integrated LM5177 controller (Texas Instruments) reduces system complexity and the number of required components.

A Breakthrough in Photovoltaic Applications

Thanks to its buck-boost converter topology, the EPC9178 maximizes energy harvesting from each solar panel, regardless of environmental conditions. This solution combines the advantages of microinverters and string inverters, delivering high energy efficiency and compatibility with existing infrastructure.

Summary

GaN technology opens up new possibilities for photovoltaic systems, offering higher performance, lower costs, and easier integration with existing setups. The EPC9178 is an excellent choice for companies and installers looking to elevate their solar installations to a new level of efficiency.
