PCIM: TI unveils 650V three-phase IPM

This 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.

Commented Giovanni Campenella, General Manager Appliances, Buildings and Factory Automation for TI, “Globally, efficiency standards such as SEER, MEPS, Energy Star and Top Runner are becoming increasingly stringent and designers are striving to meet these standards to support global environmental sustainability goals. It’s a topic I discuss weekly with customers– how we can more easily meet these standards while also addressing their consumers’ demand for systems that are reliable, quiet, compact and affordable.”

“The challenge for engineers is to design smaller motor drives that are more reliable and energy-efficientwithout adding cost, he added. “Technology solutions today require trade-offs between one or more of these consumer priorities.”

“By leveraging GaN technology, engineers using the DRV7308 can deliver more than 99% efficiency and improve thermal performance in motor driver systems, with 50% reduced power losses compared to existing solutions,” says Dung Dang, TI’s General Manager for its DC Motor Drives product line. “In addition, this device 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.”

Enabled by GaN technology, the DRV7308 delivers high power density, which coupled with its high efficiency, eliminates the need for an external heatsink, resulting in motor drive inverter printed circuit board (PCB) size reduction of up to 55% compared to IGBT and MOSFET solutions,” Dang explains.

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.

Pre- production quantities of the DRV7308three-phase, 650V integrated GaN IPM are available for purchase now on TI.com. Pricing starts at US$5.50 in 1,000-unit quantities.

The DRV7308EVM evaluation module is also available at US$250.
