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

Information highlights

• 650V clever energy module (IPM) permits greater than 99% inverter effectivity for home equipment and HVAC methods by integrating TI’s gallium nitride (GaN) know-how.
• Engineers can scale back answer dimension by as much as 55% because of the IPM’s excessive integration and its effectivity which removes the necessity for an exterior warmth sink.

Texas Devices (TI) (Nasdaq: TXN) at present launched the {industry}’s first 650V three-phase GaN IPM for 250W motor drive purposes. The brand new GaN IPM addresses most of the 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 permits greater than 99% inverter effectivity, optimized acoustic efficiency, decreased answer dimension and decrease system prices. It’s on show on the Energy Electronics, Clever Movement, Renewable Vitality and Vitality Administration (PCIM) Convention, held June 11-13 in Nuremberg, Germany.

“Designers of high-voltage residence home equipment and HVAC methods are striving to satisfy greater energy-efficiency requirements to assist environmental sustainability targets around the globe, mentioned Nicole Navinsky, Motor Drives enterprise unit supervisor at TI. “They’re additionally addressing client demand for methods which are dependable, quiet and compact. With TI’s new GaN IPM, engineers can design motor driver methods that delivers all of those expectations and operates at peak effectivity.”

Enhance system effectivity and reliability with TI GaN

Worldwide effectivity requirements for home equipment and HVAC methods reminiscent of SEER, MEPS, Vitality Star and Prime Runner have gotten more and more stringent. The DRV7308 helps engineers meet these requirements, leveraging GaN know-how to ship greater than 99% effectivity and enhance thermal efficiency, with 50% decreased 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 greater 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 might enhance reliability and prolong the lifetime of the system.

To study extra about the advantages of GaN know-how, learn the white paper, “How three-phase built-in GaN know-how maximizes motor-drive efficiency.”

Superior integration and excessive energy density scale back answer dimension and prices

Supporting the development of extra compact residence home equipment, the DRV7308 helps engineers develop smaller motor drive methods. Enabled by GaN know-how, 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 motor drive inverter printed circuit board (PCB) dimension discount of as much as 55% in comparison with competing IPM options. The mixing of a present sense amplifier, safety options and inverter stage additional reduces answer dimension and value.
