Internal redundancy
LEO and MEO satellites are equipped with breakthrough digital payload electronics and require high-density, high-efficiency, low-noise power delivery networks (PDNs), particularly for their advanced networking ASICs. These power delivery solutions must also be tolerant to both TID (total ionizing dose) radiation and SEE (single event effects).
Vicor radiation-tolerant power modules enable the ideal Power Delivery Network (PDN) for today’s LEO and MEO satellites, providing high efficiency, high density, low-noise voltage conversion to power advanced network communication ASICs and processors to provide on orbit decision-making.
By delivering high-density power with minimal footprint, real-time processing is possible while maintaining reliable space operations.
Vicor Factorized Power Architecture allows for voltage transformation to occur as close to the processor as possible, significantly reducing distribution losses to best serve onboard processors with demanding low-voltage, high-current requirements.
Modular power delivery networks adapt to varying satellite sizes and mission profiles. This compact power design allows for seamless integration across different spacecraft and supports long-term sustainability, optimizing performance as space technology evolves.
Low noise zero-current and zero-voltage switching reduce electrical interference. Minimizing unwanted signals enhances signal integrity, allowing AI-driven satellites to process data accurately and quickly.
Single event functional interrupt (SEFI) immunity is achieved using a redundant architecture in each module, where two identical and parallel powertrains with fault-tolerant control ICs are housed in a single, high-density module. If one power path is disrupted, its protection circuits force a power-off-reset. The second seamlessly maintains full operation until the reset interval is complete and both powertrains are operating in parallel again. This redundant design strengthens long-term stability, enabling AI-driven satellites to function autonomously and efficiently in space.
分比式電源架構 「FPA」將傳統單功能 DC-DC 轉換器的功率因數分解爲兩個不同的功能和電源模組:前置穩壓模組「PRM」和變壓模組 「VTM」。各模組的電源開關拓撲和控制系統都通過零電流、零電壓開關進行了優化,支持低雜訊和低功耗。PRM 和 VTM 組件支持高密度、高效率、低雜訊工作,因數分解允許 VTM 佈置在負載附近,最大限度降低大電流應用的電路板損耗。
Our radiation-tolerant COTS source-to-point-of-load power delivery simplifies design by integrating the full power chain, from high-voltage bus input to low-voltage conversion, enabling faster time to market, reduced system cost, and maximized board space with compact, flight-ready components.
