GaN FETs and ICs for Solar Power Applications APPLICATION BRIEF
●GaN devices are being widely adopted for solar applications because they offer significant benefits for efficiency, size, weight, and long lifetime.
●Summary
■Compared with silicon MOSFETs and PMICs, GaN is smaller, more efficient and able to switch at a higher frequency, lower cost, and with increased reliability.
■The key advantages that GaN brings to the table is the excellent thermal performance and improved efficiency. GaN devices enable a substantial size reduction and easier cooling to avoid heat sink and complex cooling. The ultra-small RDS(on) , QG , QGD , QOSS parameters, and zero QRR allow higher efficiency, especially for hard switching topologies. Additionally, with GaN devices the switching frequency, typically 125 kHz for silicon MOSFETs, can be increased to 400 KHz–1 MHz to shrink the size of the passive components, reducing the size and weight of the total solution and for thin design for integration into panels. Excellent thermal performance and low power losses can be leveraged to increase power levels and power density. Efficiencies around 98%, 3% higher than silicon MOSFET solutions, can be achieved with GaN. Finally, solar solutions need to be able to guarantee more than 20 years of life, and the excellent GaN reliability of GaN and high fault tolerance for overvoltage and overcurrent help to meet this requirement.
