텍사스 인스트루먼트(이하TI)가 작은 사이즈, 합리적인 가격, 높은 효율성에 대한 시장의 요구를 한 번에 잡을 수 있는 GaN 기술을 활용한 지능형 전력 모듈(IPM)을 출시했다.
TI 650V IPM GaN Technology Integration… 99%+ Inverter Efficiency in Home Appliances and HVAC Systems
No external heatsink required… PCB size can be reduced by up to 55% compared to competing IPM solutions
Texas Instruments (TI) has launched an intelligent power module (IPM) using GaN technology that can simultaneously satisfy the market's demands for small size, reasonable price, and high efficiency.
TI held a media briefing on the 13th and introduced the industry's first 650 V 3-phase GaN IPM for 250 W motor drive applications.
“Consumer priorities continue to evolve as the market demands smaller size, more cost-effectiveness and higher efficiency for consumer electronics design,” said Charile Munoz, marketing manager for TI’s Motor Drives business unit. “TI’s new DRV7308 GaN IPM addresses this demand by delivering greater than 99 percent inverter efficiency, optimized acoustic performance, reduced solution size and reduced system cost.”

TI's new products enable engineers to design and manufacture major home appliances, heating, It is expected to solve many design and performance degradation problems commonly encountered when designing ventilation and air conditioning (HVAC) systems.
Today, global efficiency standards for appliances and HVAC systems are becoming more stringent, including Seasonal Energy Efficiency Ratio (SEER), Minimum Energy Performance Standards (MEPS), Energy Star, and Top Runner.
TI's DRV7308 leverages GaN technology to help engineers meet these standards by delivering greater than 99 percent efficiency while reducing power loss by 50 percent over existing solutions and improving thermal performance.
Additionally, TI's DRV7308 achieves the industry's lowest dead time and lowest propagation delay (both less than 200 ns), enabling higher pulse-width modulation (PWM) switching frequencies that reduce audible noise and system vibration.
In addition to these advantages, the DRV7308's high power efficiency and integrated features can reduce motor heat generation, thereby improving reliability and extending system life.
Supporting the trend toward increasingly smaller home appliances, TI's DRV7308 helps engineers develop smaller motor drive systems.
“The new IPM implemented with GaN technology delivers high power density in a 12 mm × 12 mm package and is the industry’s smallest IPM for 150 W to 250 W motor drive applications,” said Krushal Shah, manager of TI’s motor drive systems applications segment. “In particular, the DRV7308’s high efficiency eliminates the need for a separate external heatsink, which can reduce the size of the motor drive inverter printed circuit board (PCB) by up to 55 percent compared to competing IPM solutions.”Did.

He added that it also has the advantage of integrating the current sense amplifier, protection functions, and inverter stage, further reducing solution size and cost.
The new products introduced today are currently being supplied by TI, and you can check the products and evaluation modules on the TI website.
“Today’s high-voltage appliance and HVAC system engineers are working to meet higher energy efficiency standards to support global environmental sustainability goals,” said Nicole Navinsky, manager of TI’s motor drive business unit. “TI’s new GaN IPMs enable engineers to design motor driver systems that meet all of these expectations and operate at the highest efficiency possible.”
