TI unveils {industry}’s first GaN IPM to allow smaller energy-efficient high-voltage motors

“With TI’s new GaN IPM, engineers can design motor driver methods that ship all these expectations and function at peak effectivity.”

Texas Devices (TI)  launched the {industry}’s first 650V three-phase GaN IPM for 250W motor drive purposes. The brand new GaN IPM addresses many design and efficiency compromises engineers usually face when designing main residence home equipment and heating, air flow and air-conditioning (HVAC) methods. The DRV7308 GaN IPM allows greater than 99% inverter effectivity, optimized acoustic efficiency, diminished resolution measurement and decrease system prices. It’s on show on the Energy Electronics, Clever Movement, Renewable Power and Power Administration (PCIM) Convention.

Texas Devices Included is a world semiconductor firm that designs, manufactures, checks and sells analogue and embedded processing chips for markets akin to industrial, automotive, private electronics, communications gear and enterprise methods.

Nicole Navinsky, Motor Drives enterprise unit supervisor at TI stated “Designers of high-voltage residence home equipment and HVAC methods are striving to satisfy larger energy-efficiency requirements to assist environmental sustainability objectives world wide. They’re additionally addressing shopper demand for methods which can be dependable, quiet and compact. With TI’s new GaN IPM, engineers can design motor driver methods that ship all these expectations and function at peak effectivity.”

Benefits of the primary GaN IPM                                                                                

1. Improves system effectivity and reliability with TI GaN

Worldwide effectivity requirements for home equipment and HVAC methods akin to SEER, MEPS, Power Star and Prime Runner have gotten more and more stringent. The DRV7308 helps engineers meet these requirements, leveraging GaN expertise to ship greater than 99% effectivity and enhance thermal efficiency, with 50% diminished energy losses in comparison with current options.

As well as, the DRV7308 achieves industry-low lifeless time and low propagation delay, each lower than 200ns, enabling larger pulse-width modulation (PWM) switching frequencies that scale back audible noise and system vibration. These benefits plus the upper energy effectivity and built-in options of the DRV7308 additionally scale back motor heating, which improves reliability and extends the system’s lifetime. 

2. Superior integration and excessive energy density

Supporting the pattern of extra compact residence home equipment, the DRV7308 helps engineers develop smaller motor drive methods. Enabled by GaN expertise, the brand new IPM delivers excessive energy density in a 12mm-by-12mm bundle, making it the {industry}’s smallest IPM for 150W to 250W motor-drive purposes. Due to its excessive effectivity, the DRV7308 eliminates the necessity for an exterior heatsink, leading to a motor drive inverter printed circuit board (PCB) measurement discount of as much as 55% in comparison with competing IPM options. The combination of a present sense amplifier, safety options and inverter stage additional reduces resolution measurement and price.

Guests to PCIM can see new merchandise and options from TI are enabling the transition to a extra sustainable future with dependable high-voltage expertise. TI can be demonstrating a brand new 800V, 750kW SiC-based scalable traction inverter system for EV six-phase motors, in collaboration with EMPEL Techniques.
