高性能的连接
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).
Ideal power delivery
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.
High performance power modules optimized for high current delivery
High density
By delivering high-density power with minimal footprint, real-time processing is possible while maintaining reliable space operations.
高效率
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.
Scalability
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
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.
Dual powertrain, fault-tolerant modules
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.
Vicor 分比式电源架构，理想的负载点电源系统
分比式电源架构 (FPA) 将传统单功能 DC-DC 转换器的功率因数分解为两个不同的功能和电源模块：前置稳压模块 (PRM) 和变压模块 (VTM)。各模块的电源开关拓扑和控制系统都通过零电流、零电压开关进行了优化，支持低噪声和低功耗。PRM 和 VTM 组件支持高密度、高效率、低噪声工作，因数分解允许 VTM 布置在负载附近，最大限度降低大电流应用的电路板损耗。
Complete radiation-tolerant COTS solution
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.
