EL SEGUNDO, CA, UNITED STATES – Efficient Power Conversion Corporation, the world leader in enhancement-mode gallium nitride (eGaN®) power devices, proudly announces the launch of the EPC9178, the latest reference design for photovoltaic (PV) optimizers. Designed to deliver high reliability while addressing critical challenges in energy efficiency and cost-effectiveness through the reduction of passive components in solar energy systems, the EPC9178 demonstrates the transformative potential of GaN technology for renewable energy solutions.
The EPC9178 reference design employs a back-to-back buck-boost converter topology, ensuring optimal energy harvesting for each solar panel, even under challenging conditions such as shading. This compact, high-performance solution bridges the gap between micro-inverters and string inverters, offering enhanced energy efficiency and compatibility with existing infrastructure.
EPC9178 Key Features
The EPC9178 combines cutting-edge GaN technology with an advanced, dedicated controller to deliver unmatched performance and reliability.
• Compact Design: High-frequency operation at 450 kHz minimizes the size of passive components, resulting in a lightweight and space-saving solution.
• High Efficiency: Achieves up to 98% peak efficiency, reducing power losses and improving thermal management.
• Advanced GaN Technology: Powered by 100 V-rated EPC2306 eGaN® FETs, the EPC9178 offers low on-resistance (3.8 mΩ) and reduced switching losses compared to silicon MOSFETs.
• Simplified Control: Integrated LM5177 controller from Texas Instruments reduces design complexity and component count.
• Versatile Output Settings: Operates across an input voltage range of 30 V to 60 V, with selectable output voltages of 30 V, 45 V, and 60 V.
“The EPC9178 delivers a compact, high-performance, and reliable design that enables cost-effective solar energy systems,” said Alex Lidow, CEO of EPC.
