Navitas Semiconductor Revolutionizes Power with GaN Innovations

Navitas Semiconductor Unveils Groundbreaking Power Solutions

In an exciting development for the power semiconductor industry, Navitas Semiconductor (Nasdaq: NVTS) has introduced a revolutionary two-in-one solution: the world’s first production-released 650 V bi-directional GaNFast ICs. This innovation marks a significant transition in power conversion technology, simplifying power architectures through single-stage bi-directional switch (BDS) converters.

Transforming Power Converters with Single-Stage Technology

The vast majority of high-voltage power converters currently utilize a two-stage topology, which typically consists of a power-factor-correction (PFC) stage followed by a DC-DC stage. These designs can inadvertently lead to systems that are bulky, costly, and inefficient due to the need for large DC-link buffering capacitors. The new single-stage BDS converters from Navitas eliminate these challenges, combining both functions into a streamlined, high-efficiency stage.

This technological leap is not just theoretical; leading manufacturers in the electric vehicle (EV) and solar micro-inverter sectors are already integrating these new BDS converters to enhance efficiency and reduce system costs. The bi-directional GaNFast technology is proving to save up to 10% in costs, 20% in energy, and reduce physical size by up to half compared to traditional setups.

Advancements in Bi-Directional Technology

The core of this breakthrough is the bi-directional GaNFast power IC, which allows voltage blocking while facilitating current flow in both directions, significantly improving efficiency. Unlike previous designs that required two separate switches, the bi-directional GaNFast ICs represent cutting-edge monolithic integrations that optimize space, performance, and overall system effectiveness.

Market Applications and Growth Potential

Applications for these innovative converters are extensive, reaching into critical markets such as EV charging, solar inverters, energy storage, and motor drives—representing multi-billion dollar opportunities. The integration of this technology is anticipated to drive a wave of efficiency and sustainability across these industries.

Specifications of New Power Solutions

The initial lineup includes the NV6427 and NV6428, which feature R_SS(ON) ratings of 100 m? and 50 m?, respectively. Packaged in thermally enhanced formats, these devices are ready for immediate deployment into various high-voltage applications.

To complement the bi-directional GaNFast ICs, Navitas has also released its IsoFast devices, optimized drivers that enhance the bi-directional GaN operation. These drivers boast impressive transient immunity and eliminate the need for external bias supplies, ensuring reliable operation in diverse power scenarios.

Leadership and Commitment to Sustainable Energy

Gene Sheridan, co-founder and CEO of Navitas, emphasized the transformative impact of this technology on the future of electrification. He stated, "The future is a bi-directional energy flow, which can harness renewable sources and enhance the grid's efficiency, facilitating a sustainable energy landscape for generations to come." The single-stage BDS converters play a key role in driving this vision forward.

Pathway to Market Readiness

Navitas Semiconductor is not only pioneering new products but also ensuring they are accessible. Effective immediately, the bi-directional GaNFast ICs NV6427 and NV6428 are in mass production, with samples of IsoFast devices available for qualified customers. Additionally, the availability of single-stage evaluation boards and associated user guides allow developers to explore integration possibilities with ease.

Conclusion: A New Direction in Power Technology

The introduction of these bi-directional GaNFast ICs and single-stage BDS converters illustrates Navitas Semiconductor's commitment to innovation within the power semiconductor sector. With a focus on creating efficient, compact, and cost-effective solutions, Navitas continues to lead in providing the essential technology for our electrified future. As this technology continues to evolve, it promises to unlock enhanced possibilities within the energy sector that align with contemporary sustainability goals.
