Laying the Foundation for Digital Energy and Injecting Powerful “Core” Power
Since its inception, the Digital Energy Joint Laboratory has achieved a series of fruitful results, including the launch of solutions such as 4.5kW and 12kW server power supplies and a 500W single-stage microinverter. These solutions utilize advanced topologies to meet the evolving industry demands for high efficiency and high power density. The implementation of these solutions not only demonstrates the innovative strength of GigaDevice and Navitas Semiconductor in the digital energy sector, but also highlights the unique advantages and market competitiveness brought about by the integration of their technologies.
The 500W single-stage photovoltaic microinverter solution, based on GigaDevice’s GD32G553 MCU and Navitas’ bidirectional GaNFast™ gallium nitride power chips, utilizes a single-stage, one-to-one architecture, offering high efficiency, low losses, high integration, and cost optimization. Combined with an optimized hybrid modulation strategy and soft-switching technology, it achieves peak efficiency exceeding 97.5%, CEC efficiency exceeding 97%, and MPPT efficiency exceeding 99.9%. The single-stage architecture directly converts DC to AC, eliminating a DC-DC converter stage, improving power density and reducing component count and losses. Magnetic integration and Navitas’ bidirectional GaN switches further reduce size and bill of materials (BOM) costs.
Based on GigaDevice’s GD32G553 MCU, combined with Navitas’ GaNSafe™ GaN power chips and third-generation fast SiC MOSFETs, the 4.5kW and 12kW AI server power solutions are designed for AI and traditional servers, as well as hyperscale data centers. The 12kW solution not only complies with the Open Compute Project (OCP), Open Rack v3 (ORv3), and CRPS specifications, but also achieves a peak efficiency of 97.8% while exceeding the 80 PLUS Ruby standard with a minimalist component layout.
Moving towards a global energy transition, promoting the integration of green and intelligent technologies
Amid the global energy transition, demand for digital energy solutions is rapidly growing. Emerging technologies such as AI, big data, and cloud computing are driving transformation in the energy industry. Especially in the fields of green energy and intelligent power management, innovative technologies and system integration have become key to achieving more efficient, environmentally friendly, and sustainable power systems.
At the unveiling ceremony, Huang Xiucheng, Vice President of System Application Engineering at Navitas Semiconductor, and Li Baokui, Senior Vice President and General Manager of the MCU Business Unit at GigaDevice, jointly unveiled the laboratory and engaged in in-depth discussions on future collaboration directions and the laboratory’s operational model. Both parties expressed their commitment to using the joint laboratory as a platform to deepen technological collaboration and accelerate the application of innovative research results.
Huang Xiucheng, Vice President of System Application Engineering at Navitas Semiconductor, said, “The establishment of the joint laboratory marks a significant milestone in the deepening strategic collaboration between Navitas Semiconductor and GigaDevice. We will leverage the advantages of GaN technology in efficient power management and, combined with GigaDevice’s deep expertise in MCUs, jointly develop future-oriented digital energy solutions, bringing more efficient and environmentally friendly innovative products to global customers.”
Li Baokui, Senior Vice President and General Manager of the MCU Business Unit at GigaDevice, said, “Digital energy is one of GigaDevice’s core application areas. Through our collaboration with Navitas Semiconductor, we will deeply integrate our high-performance GD32 MCU with leading GaNFast™ GaN technology to provide customers with more competitive solutions. This is not only a collaborative innovation at the technical level, but also a firm commitment by both parties to promote green energy and empower the intelligent transformation of industries.”
The establishment of this joint laboratory not only recognizes the achievements of GigaDevice and Navitas Semiconductor’s previous collaboration, but also heralds broad prospects for cooperation between the two parties in the digital energy sector. Going forward, the laboratory will continue to focus on technological innovation, accelerating the implementation of efficient power management solutions in more application scenarios and driving high-quality development in the digital energy industry.
