DC-DC 高電圧電源
フォーム、フィット、ファンクションを考えた設計
スペルマンのUMシリーズ、プリント回路基板マウント型高圧 モジュールは、一部の他社製品と取り付け・形状が同等であるた め容易な置き換えが可能です。 た、低価格で他にはない付加的 機能と利便性を提供します。この表面実装(SMT)ベースの高圧 モジュールは、独自開発の電力変換技術とスペルマンの60年に わたる高圧電源開発経験を かし、性能・信頼性の向上はもとよ り、他社製品に比べて低価格で、しかもシステムへの統合がこれ までより簡単です。
先進的な電力変換トポロジ
UMコンバータは当社独自開発のゼロ電圧スイッチング電力変 換トポロジを駆使し、これまでにない効率を提供する一方で、そ れに伴うノイズおよびリップル出力を低減します。従来のスイッ チングトポロジに比べて放射ノイズが少ないため、隣接する電気 回路から遮蔽する必要がほとんどなく、場合によっては全く必要 ありません。
高圧出力はフェライトコア高圧ステップアップ変圧器を使って 発生し、半波長コッククロフト・ウォルトン電圧マルチプライ ヤーへ送られ、指定の高圧出力が得られます。
高周波電力変換のスイッチング速度が固定されているため、出 力キャパシタンスが小さく、結果として蓄積エネルギーが最小限 に抑えられます。定格出力を抑えたサージ保護用抵抗と高速作動 電流ループを使うことで、アーク放電および短絡から完全に保護 します。
制御とレギュレーション
実際に発生する出力電圧は高インピーダンスのデバイダで抽出 され、電圧フィードバック信号が生成されます。電流フィードバッ ク信号は、電圧センス抵抗を介して高圧出力回路の低圧端側の帰 路に生成されます。この2つの正確なグランドリファレンス 力 電圧フィードバック信号は、装置の正確なレギュレートおよび制 御に使われるほか、外部モニタリングにも使われます。
UMの特異な変換トポロジにより、低インピーダンス負荷また は短絡回路の場合も全電流を印加することが可能です。標準装置 は最大定格出力の103%に制限されます。
標準インターフェース
スペルマンのUMシリーズのインターフェースは電流プログラ ミング能力を備え、正極性、バッファ付き、低出力インピーダン スの電圧および電流モニター信号を生成します(0~+4.64 Vdc は0~定格全出力に相当します)。電圧プログラミング信号は0~ +4.64 Vdcが0~100%定格電圧と等しい場合に提供されます。 この電力プログラミング能力により、電流制限をゼロから最大 出力電流の100%の範囲で設定可能です。この特性は、全出力 電流より低い出力をご希望の場合、例えば高感度負荷を保護する 場合などに有用です。
バッファ付き低インピーダンス電圧および電流モニター信号は、 外部回路を直接駆動することができる一方、負荷効果およびピッ クアップ効果を最小限に抑えます。この機能特性は、信号の質を 向上させると同時に、外部インターフェース緩衝回路を付加する 手間とコストを節減します。
この標準インターフェースはピン間隔0.1インチの13ピン配 列で提供されます。現在市場で入手可能な電源と互換性のあるイ ンターフェース(0.2インチ間隔の7ピン)をご希望の場合、オプ ション “L”を発注いただければ結構です。
機械装置および環境に関する考慮
UMシリーズは密閉型、プリント基板実装が可能の、プラスチッ ク製ケースに収められたコンバータです。どの装置も、エポキシ よりはるかに軽いシリコン主体のポッティング剤で密閉されてい ます。絶縁された非接地2-56機械加工スクリューを使って、モ ジュールがプリント基板にしっかり固定されますので、インター フェースピンに機械的ストレスがかかりません。マウント用のプ レート、ブラケット、フランジマウント用のオプションも用意さ れて ます。高圧出力は最短長914.4mmの、適切な定格の高圧 配線を介して提供されます。

Programming and Monitor Signals
Voltage and current programming is done via positive polarity, high input impedance, 0 to 4.64Vdc signals.
Voltage and current monitors are positive polarity, buffered low output impedance 0 to 4.64Vdc signals.
I Mon
The I Mon signal is a true output current monitoring signal. All internal offsets due to feedback divider currents have been compensated for.
Signature Resistor
A unique identifying signature resistor for each type of unit is connected from Pin 1A to ground. Details if desired are available upon request.
I Sense Signal
The polarity of the I Sense signal is opposite of the polarity of the output voltage of the unit that generated it. So a positive output polarity unit creates a negative polarity current monitor signal; while a negative output polarity unit creates a positive polarity current monitoring signal. This signal is clamped to ground internally via a bidirectional transient protection device and the signal is made available via a series connected 47kΩ isolation resistor. Internal HV dividers create a small,
linear offset voltage on this current monitor signal that can be compensated for.
OT Output
The unit is protected by an internal thermostat that will shut the unit off if the case temperature exceeds 65°C. The OT Output signal will change states indicating an over temperature fault has occurred. In order to clear the OT signal and re-enable the unit, the temperature has to drop below 55 degrees C and input power needs to be recycled. For details on unit cooling requirements and the OT Output signal please see the operator’s manual.
