- **650V Intelligent Power Module (IPM)**: More than 99% inverter efficiency for appliances and HVAC systems by integrating TI's gallium nitride (GaN) technology.
- **Compact Design**: Engineers can reduce solution size by up to 55% as a result of the IPM's high integration and efficiency, eliminating the need for an external heat sink.
Hey there, tech enthusiasts! Big news out of Dallas today – Texas Instruments (TI) has just dropped the industry's first-ever 650V three-phase GaN IPM for 250W motor drive applications. This isn’t just any old tech upgrade; it’s a game-changer for high-voltage motors, especially in home appliances and HVAC systems.
With the new DRV7308 GaN IPM, you’re looking at more than 99% inverter efficiency. That means optimized acoustic performance, a smaller footprint, and lower system costs. No more design compromises or performance bottlenecks. It's on display at the Power Electronics, Intelligent Motion, Renewable Energy and Energy Management (PCIM) Conference in Nuremberg, Germany.
So, what's all the fuss about? Well, for starters, this GaN IPM helps meet increasingly stringent global efficiency standards like SEER, MEPS, Energy Star, and Top Runner. It leverages cutting-edge GaN technology to deliver breathtaking efficiency, with more than 99% and improved thermal performance. We’re talking 50% reduced power losses compared to existing solutions.
But wait, there's more! The DRV7308 achieves industry-low dead time and low propagation delay, both clocking in at under 200ns. This allows for higher pulse-width modulation (PWM) switching frequencies, which translates to reduced audible noise and system vibration. Plus, the higher power efficiency and integrated features reduce motor heating, boosting reliability and extending the system’s lifespan.
In the era of compact appliances, the DRV7308 is a blessing. This new IPM, enabled by GaN technology, delivers high power density in a tiny 12mm-by-12mm package. It’s the industry's smallest IPM for 150W to 250W motor-drive applications. And because it’s so efficient, it eliminates the need for an external heatsink. This results in a motor drive inverter PCB size reduction of up to 55% compared to competing IPM solutions.
The integration doesn’t stop there. The DRV7308 also features a current sense amplifier, protection features, and an inverter stage, further reducing solution size and cost. Now, that’s what we call advanced integration!
Curious about what else TI has up its sleeve? Head over to Hall 7, Booth 652 at PCIM 2024. You’ll get to see new products and solutions from TI that are paving the way for a more sustainable future with reliable high-voltage technology.
Highlights include a next-gen electric vehicle (EV) propulsion system, featuring a new 800V, 750kW SiC-based scalable traction inverter system for EV six-phase motors. This demo showcases high power density and efficiency using TI’s high-performance isolated gate drivers, isolated DC/DC power modules, and Arm® Cortex®-R MCUs.
Additionally, don’t miss TI’s experts like Sheng-Yang Yu and Harald Parzhuber speaking at various panels throughout the event. They’ll be tackling topics from SiC vs. GaN to the future of power systems.
