優れた接続性

低軌道・中軌道衛星に搭載されているデジタル機器は飛躍的進歩を遂げており、特にそこで使われる高性能ネットワークASICには高電力密度、高効率で低ノイズの電力供給ネットワーク(PDN)が必須です。またこれらの配電ソリューションはTID（トータルドーズ）やSEE（シングルイベント効果）への耐性も備えなくてはなりません。

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.

大電流供給に最適な高性能電源モジュール

高電力密度

By delivering high-density power with minimal footprint, real-time processing is possible while maintaining reliable space operations.

高効率

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.

スケーラビリティ

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.

低ノイズ

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.

フォルトトレランスのための電力変換部二重化

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.

理想的なPoL電源システム:
Vicorのファクトライズド・パワー・アーキテクチャ(FPA)

ファクトライズド・パワー・アーキテクチャ (FPA) とは、従来の単体のDC-DCコンバータを、機能別に電源モジュールに分解した構成です。電圧調整機能のモジュールであるPRMと変圧機能モジュールVTMです。電力変換のスイッチング方式と制御方式には、ゼロ電圧・ゼロ電流スイッチング技術を使っており、それぞれのモジュールで最適化されて、低ノイズ・低損失を実現しています。PRMとVTMの各コンポーネントは高電力密度・高効率・低ノイズの電源モジュールです。VTMは変圧の機能のみとすることで小型にできるため負荷の近くに置くことができます。大電流のアプリケーションで基板の配電損失を最小限に抑えることができます。
