Power Integrations | March 21, 2023
Power Integrations, the leader in high-voltage integrated circuits (ICs) for energy-efficient power conversion, today announced a 900-volt gallium-nitride (GaN) extension to the company’s InnoSwitch3™ family of flyback switcher ICs. The new ICs, which feature the company’s proprietary PowiGaN™ technology, deliver up to 100 watts with better than 93 percent efficiency, eliminating the need for heat sinks and streamlining design of space-challenged applications. InnoSwitch3 designs also offer exceptional light-load efficiency making them ideal for providing auxiliary power in electric vehicles during low-power sleep modes. The AEC-Q100-qualified InnoSwitch3-AQ family is particularly suitable for EVs based on 400-volt bus systems where the 900-volt PowiGaN switch provides more power and increased design margin―required for 12-volt battery-replacement systems―with enhanced efficiency over silicon-based converters.
“The dominant bus voltage for electric vehicles is 400 volts,” stated Peter Vaughan, automotive business development director at Power Integrations. “EV manufacturers are optimizing their new generation of 400-volt systems and re-engineering various power stages in the vehicle, such as the on-board charger. The 900-volt PowiGaN switch is extremely beneficial because it easily accommodates inductive noise spikes, yet it can operate from as low as 30 VDC, enabling systems to meet functional safety active discharge requirements. The extra power delivered by our GaN technology matches the increasing power demands of EV manufacturers, moreover, efficiency in power conversion―even in auxiliary systems―is important for both range extension and thermal management.”
In the industrial space, extra power and increased efficiency are extremely advantageous in applications such as appliances, three-phase motors and auxiliary power supply units (PSUs) in servers. The new 900-volt parts are pin-for-pin compatible with existing 725-volt and 750-volt InnoSwitch3-EP parts and offer increased safety margin which is ideal for countries with unstable line voltages.
“Our ability to deliver GaN parts rated at up to 900 volts demonstrates the reliability and ruggedness of our PowiGaN technology,” stated Silvestro Fimiani, senior product marketing manager at Power Integrations.
The new 900-volt InnoSwitch3-EP and InnoSwitch3-AQ off-line CV/CC flyback switcher ICs employ synchronous rectification, a valley switching discontinuous conduction mode (DCM) and continuous conduction mode (CCM) flyback controller. FluxLink™ communication technology enables the IC package to bridge the isolation barrier, optimizing efficiency and eliminating the need for optocouplers. PowiGaN technology enables InnoSwitch3-EP ICs to deliver up to 100 watts (230 volts alternating current [VAC] plus or minus 15 percent) without heat sinks. InnoSwitch3-EP devices incorporate multiple protection features including line over- and under-voltage protection, output over-voltage and over-current limiting, and over-temperature shutdown. Devices are available with standard and peak power delivery options. Automotive InnoSwitch3-AQ devices can also deliver 100 watts from a 400-volt bus and provide performance and protection features similar to those of the popular 1700-volt silicon-carbide InnoSwitch3-AQ ICs currently used in 800-volt EV systems.

BlueWave | March 20, 2023
BlueWave Solar, a leading solar and battery storage developer in the Northeast U.S., recently announced an official name change to BlueWave, heralding expansive growth beyond solar development into additional areas of the clean energy space. BlueWave's expertise and suite of capabilities now encompasses the development, engineering, construction and ownership of solar, solar plus storage, and standalone battery storage projects.
The name change, while subtle, marks a significant next phase of growth, fueled by resources and funding from its new parent company, Axium Infrastructure, an infrastructure investment management firm with a deep North American renewables portfolio. The 100% stake acquisition, completed in May 2022, has allowed BlueWave to expand its leadership in innovative solar development and grow into the long-term asset ownership of its development pipeline and also expansion into battery storage, both coupled with solar and as standalone assets.
"We are on a journey to transform access to renewable energy and strive to develop and build the most effective systems to make that possible," Trevor Hardy, CEO and Co-Founder of BlueWave noted. "Our capabilities now go beyond solar development, and we are better poised to address and innovate how energy is stored and transmitted, ultimately creating greater access. Increasing battery storage on the U.S. electric grid is absolutely critical in order to achieve our nation's economic and climate goals. We welcome this next chapter for our team as we continue to push the boundaries of a clean energy future."
Battery storage is an integral part of renewable deployment—it is critical to the effectiveness of clean energy initiatives and vital to the stabilization and integration of renewables to the existing grid. Battery storage enables further decarbonization of the utility grid by allowing solar and wind energy to contribute to the available electricity supply, even when the sun isn't shining or the wind isn't blowing, by storing and then releasing energy when it's needed most. BlueWave committed to pursuing battery storage development in 2021 and is proud to bring its thoughtful approach to development and energy expertise to the deployment of both distribution and transmission scale battery storage assets.
BlueWave is in the early stages of battery storage development within multiple states that have battery storage policies in place including Maine, Massachusetts, and New York, and has been working with local municipalities and state policy makers to best understand and meet storage needs on a local, state and regional basis. The potential community benefits from battery storage are substantial, including local revenue to landowners, improved grid reliability during summer peaks, a cleaner environment that is free of fossil fuels and robust job growth in the burgeoning cleantech economy.
"Battery storage is an essential part of the conversation that cannot be ignored as we seek to decarbonize the electric grid," said Mike Marsch, Chief Development Officer of BlueWave. "Given our proven success with solar development and ability to work collaboratively with local communities and state policymakers to achieve outcomes benefiting all involved, we believe that our added battery storage capabilities will contribute immensely to our overall positive impact on the world. We seek to support our communities by enhancing grid reliability while also facilitating much needed climate policy guidance across multiple states."
BlueWave's vision is to protect our planet by transforming access to renewable energy. As a pioneering renewable energy company that develops and owns solar and battery storage projects, BlueWave has developed and built more than 150 MW of solar projects to date and is actively developing battery storage projects to ensure our grid is reliable and efficient in a clean energy future. As built, these projects collectively generate enough solar energy to avoid more than 144,000 metric tons of carbon emissions annually.
