Texas Instruments (TI) unveiled the first three-phase, 650V GaN IPM DRV7308 in the market for applications involving 250W motor drives. When developing big household appliances and HVAC (heating, ventilation, and air conditioning) systems, engineers often have to make trade-offs between design and performance.
The new three-phase, 650V GaN IPM solves many of these issues. More than 99% inverter efficiency, improved acoustic performance, smaller solution sizes, and lower system costs are all made possible by the DRV7308 GaN IPM.
It is on display at the Power Electronics, Intelligent Motion, Renewable Energy and Energy Management (PCIM) Conference, held June 11-13 in Nuremberg, Germany.
“Designers of high-voltage home appliances and are striving to meet higher energy-efficiency standards to support environmental sustainability goals around the world, said Nicole Navinsky, Motor Drives business unit manager at TI. “They are also addressing consumer demand for systems that are reliable, quiet and compact. With TI’s new GaN IPM, engineers can design motor driver systems that delivers all of these expectations and operates at peak efficiency.”
Improve system efficiency and reliability with TI GaN
Worldwide efficiency standards, such Energy Star, MEPS, Top Runner, SEER, and MEPS, are getting harder to meet for HVAC systems and appliances. By utilizing GaN technology to provide greater than 99% efficiency and enhance thermal performance with 50% less power losses than current alternatives, the DRV7308 GaN IPM assists engineers in meeting these goals.
Furthermore, the DRV7308 attains sub-200ns propagation delay and industry-low dead time, allowing for greater pulse-width modulation (PWM) switching frequencies that lessen system vibration and audible noise. In addition to these benefits, the DRV7308’s integrated features and increased power efficiency help lessen motor heating, which can increase system longevity and dependability.
Advanced integration and high power density reduce solution size and costs
The DRV7308 aids engineers in creating more compact motor drive systems, which contributes to the trend of smaller household appliances. Made possible by GaN technology, the new IPM is the smallest in the market for 150W to 250W motor-drive applications, yet it still offers great power density in a 12mm-by-12mm size.
Compared to rival IPM systems, the DRV7308’s high efficiency removes the requirement for an external heatsink, resulting in a motor drive inverter printed circuit board (PCB) footprint reduction of up to 55%. Further reducing solution size and cost is the incorporation of an inverter stage, protective features, and a current sensing amplifier.
The most recent example of TI breakthroughs helping to overcome engineering problems and improve motor designs is this high-voltage, high-efficiency GaN IPM.
TI’s reliable high-voltage technology at PCIM 2024
At PCIM, attendees may view innovative TI products and solutions in Hall 7, Booth 652, which are facilitating the shift to a more sustainable future with dependable high-voltage technology.
Among the TI highlights at PCIM, besides the DRV7308 GaN IPM, are:
Next-generation electric vehicle (EV) propulsion system: TI is demonstrating a new 800V, 750kW SiC-based scalable traction inverter system for EV six-phase motors, in collaboration with EMPEL Systems. The demonstration features high power density and efficiency using TI’s high-performance isolated gate drivers, isolated DC/DC power modules and Arm® Cortex®-R MCUs.
Speaking session: TI’s manager of high-voltage power systems applications, Sheng-Yang Yu, will speak on June 11 at Markt & Technik panel discussion: “Will SiC ultimately Hold its Own against GaN?”
Speaking session: TI’s manager of renewable energy systems, Harald Parzhuber, will speak on June 12 at Bodo’s Power Systems panel discussion: “GaN Wide Bandgap Design, the Future of Power.”
