DALLAS, June 11,
2024 /PRNewswire/ -- Texas Instruments (TI) (Nasdaq:
TXN) today introduced the industry's first 650V three-phase GaN IPM
for 250W motor drive applications. The new GaN IPM addresses many
of the design and performance compromises engineers typically face
when designing major home appliances and heating, ventilation and
air-conditioning (HVAC) systems. The DRV7308 GaN IPM enables more
than 99% inverter efficiency, optimized acoustic performance,
reduced solution size and lower system costs. It is on display at
the Power Electronics, Intelligent Motion, Renewable Energy and
Energy Management (PCIM) Conference, held June 11-13 in Nuremberg, Germany.
For more information, see ti.com/DRV7308.
"Designers of high-voltage home appliances and HVAC systems 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 deliver
all of these expectations and operates at peak efficiency."
Improve system efficiency and reliability with TI
GaN
Worldwide efficiency standards for appliances and HVAC
systems such as SEER, MEPS, Energy Star and Top Runner are becoming
increasingly stringent. The DRV7308 helps engineers meet these
standards, leveraging GaN technology to deliver more than 99%
efficiency and improve thermal performance, with 50% reduced power
losses compared to existing solutions.
In addition, the DRV7308 achieves industry-low dead time and low
propagation delay, both less than 200ns, enabling higher
pulse-width modulation (PWM) switching frequencies that reduce
audible noise and system vibration. These advantages plus the
higher power efficiency and integrated features of the DRV7308 also
reduce motor heating, which can improve reliability and extend the
lifetime of the system.
To learn more about the benefits of GaN technology, read the
white paper, "How three-phase integrated GaN technology maximizes
motor-drive performance."
Advanced integration and high power density reduce solution
size and costs
Supporting the trend of more compact home
appliances, the DRV7308 helps engineers develop smaller motor drive
systems. Enabled by GaN technology, the new IPM delivers high power
density in a 12mm-by-12mm package, making it the industry's
smallest IPM for 150W to 250W motor-drive applications. Because of
its high efficiency, the DRV7308 eliminates the need for an
external heatsink, resulting in motor drive inverter printed
circuit board (PCB) size reduction of up to 55% compared to
competing IPM solutions. The integration of a current sense
amplifier, protection features and inverter stage further reduces
solution size and cost.

systems, see the GaN IPM page on TI.com.
This high-efficiency, high-voltage GaN IPM is the latest example
of TI innovations to help solve engineering challenges and
transform motor designs.
TI's reliable high-voltage technology at PCIM
2024
Visitors to PCIM can see new products and solutions
from TI that are enabling the transition to a more sustainable
future with reliable high-voltage technology in Hall 7, Booth 652.
In addition to the DRV7308 GaN IPM, TI highlights at PCIM
include:
- 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.
- TI's manager of high-voltage power systems applications,
Sheng-Yang Yu, will speak on
June 11 in the Markt & Technik
panel discussion: "Will SiC
ultimately Hold its Own against GaN?"
- TI's manager of renewable energy systems, Harald Parzhuber,
will speak on June 12 in Bodo's Power
Systems panel discussion: "GaN Wide Bandgap Design, the Future of
Power."
