Energize the Grid with Texas Instruments LMG3410 600V GaN Power Stage
GaN technology continues to help designers create smaller, more efficient power converters and enable the next generation of high-density power designs.
With an ever-increasing demand for higher power at much greater efficiencies, designers are exploring wide-bandgap technologies such as GaN for their next design. GaN technology continues to help designers create smaller, more efficient power converters and enable the next generation of high-density power designs that are faster, cooler and smaller.
To design high-density power converters, engineers must take full advantage of GaN’s inherent high switching frequency and high slew rate capabilities. The integration of driver, protection and high voltage GaN in a single power package make this possible. With Texas Instruments’ LMG3410 600-V GaN power stage, the driver integration eliminates PCB layout challenges at high switching frequencies and helps achieve zero ringing at slew rates of up to 100V/ns. And with over 10 million hours of GaN process reliability testing, TI is addressing the need for proven and ready-to-use solutions through reliable GaN products, bringing decades of silicon manufacturing expertise and advanced device-development talent to GaN technology.
Visitors to the Applied Power Electronics Conference (APEC) this year in San Antonio, Texas, witnessed the LMG3410 in action at the TI booth. Developed jointly by Siemens and TI, the 8kW Three- Phase Bidirectional Grid Link with GaN solution demonstrates a high-frequency bidirectional multilevel converter between a three-phase AC grid (400V-480V) and a DC bus (650V-800V) using the LMG3410 600V GaN power stage and C2000 dual-core Delfino real-time controller. With 99% peak efficiency and less than 1% THD, this solution delivers 8kW of power in grid-connected applications such as PV inverters, offline PFC, HEV/EV onboard chargers and high-voltage battery storage systems.
