CORTEX 系列

再生式交流電源

用於輸入與輸出驗證的雙向交流平台

CORTEX 系列可程式化交流電源（原名為 PRE / PRE-20）是一款機架式、模組化的交流電力系統，整合了「電源（Source）」與「負載（Load）」功能，專為精密交流電力測試而設計。該系統支持交流輸入擾動模擬、高達 5 kHz 的超高頻運作、硬體在環（Power HIL）整合，以及用於評估受測元件（DUT）輸出穩定性、效率與保護行為的交流回生（Sinking）模式。憑藉高精度與快速動態響應，CORTEX 系列非常適合實驗室測試台架以及與電磁相容（EMC）相關的電力測試應用。

基於上述優勢，CORTEX 交流電源採用高頻寬控制架構與快速瞬態響應技術，能夠精準複製交流電網擾動與動態負載交互作用。其細膩的輸出解析度、精確的相位控制以及任意波形編程功能，確保了電壓、頻率及不平衡條件下的測試可重複性。採用模組化機架設計，功率範圍從 3U 空間內的 22 kVA 可擴充至 220 kVA，為中功率實驗室驗證與合規性導向的交流電力測試提供高效的解決方案。

Highlighted Features

The CORTEX Series offers all-in-one source/load with advanced programming functions for complex power conditions, supporting Power Hardware-in-the-Loop (PHIL) with high bandwidth response together with built-In sandard waveforms for compliance-oriented testing.

High Dynamic Performance and Output Accuracy

The CORTEX Programmable AC Power Source is engineered for applications where fast dynamic behavior and precise output control are critical. Across its model range, including HF and SHF variants, the system delivers a wide operating bandwidth of up to 5 kHz, enabling accurate generation of rapidly changing AC waveforms without compromising stability.

High output accuracy of ±(0.01% + 0.05%) F.S. combined with a fine voltage resolution of 0.01 V ensures repeatable and reliable setting of voltage and frequency parameters. With a voltage slew rate of up to 3 V/μs, CORTEX can impose fast voltage transitions, allowing engineers to evaluate DUT response under rapid voltage variation and dynamic operating conditions with a high degree of fidelity.

高動態性能與輸出精度

CORTEX 可程式化交流電源專為對快速動態響應與精確輸出控制有極高要求的應用而設計。涵蓋包含 HF（高頻）與 SHF（超高頻）在內的全系列機種，該系統提供高達 5 kHz 的寬廣運作頻寬，能夠在不犧牲穩定性的前提下，精準生成快速變化的交流波形。

系統具備 $\pm(0.01\% + 0.05\%)$ F.S. 的高輸出精度，結合 0.01 V 的細微電壓解析度，確保了電壓與頻率參數設定的可重複性與可靠性。憑藉高達 3 V/μs 的電壓變化率（Slew Rate），CORTEX 能夠施加極速的電壓瞬變，使工程師能夠在高保真度（High Fidelity）的情況下，評估受測元件（DUT）在快速電壓變動與動態運作條件下的反應。

Four-Quadrant Bidirectional Operation with Automatic Source–Load Switching
CORTEX integrates four-quadrant operation capability, which stands for its versatile function of switching seamlessly between AC source and electronic load modes from a single bench. The mode transition is automatic in correspondence to the DUT's operating states and offers a more compact bench setup approach compared to the conventional one where additional load equipment is necessary.

When operating in load mode, CORTEX returns the power sunk from the DUT towards the facility power network through its regenerative architecture instead of dissipating it as heat. Benefiting from such a feature, the laboratory setup waives the essentialness of integrating heat management and reduces thermal stress on the test bench. This bidirectional power flow capability enables accurate evaluation of DUT behavior under operating conditions where energy exchange reverses dynamically, while maintaining stable control and high system efficiency.

四象限雙向運作與自動源載切換

CORTEX 整合了四象限運作能力，其卓越之處在於能單憑一台設備，即可在「交流電源」與「電子負載」模式之間無縫切換。此模式轉換會根據受測元件（DUT）的運作狀態自動進行；相較於傳統需額外配置負載設備的測試配置，這種方式能提供更精簡、節省空間的測試台架方案。

當運作於負載模式時，CORTEX 透過其回生式架構（Regenerative Architecture），將從受測元件吸收的電力回饋至廠區電網，而非以熱能形式消耗。得益於此特性，實驗室配置無需額外整合散熱管理系統，並能有效降低測試台架的熱應力。這種雙向功率流能力，使工程師能夠在能量交換動態反轉的運作條件下，精確評估受測元件的行為，同時保持穩定的控制與極高的系統效率。

Versatile Working Mode Supporting both AC & DC Output

CORTEX works beyond the given pattern of an AC source-load yet  further supports the function of superimposing a controlled DC component over its AC output waveform. Extending from this feature, the unit can operate in pure AC, pure DC, and composite AC+DC output modes, with which the DUT can be validated in terms of its thermal performance, control stability, and protection response against non-ideal operating conditions caused by asymmetric switching, rectification effects, and magnetic bias as if in power electronic systems.

From a test bench perspective, such a feature enables controlled assessment of thermal behavior, control stability, and protection response under non-ideal but realistic operating conditions.

多功能運作模式：全面支援交流 (AC) 與直流 (DC) 輸出

CORTEX 的功能超越了傳統交流源載系統的範疇，進一步支援在交流輸出波形上疊加受控的直流分量（DC Component）。基於此特性，該設備可運作於純交流 (Pure AC)、純直流 (Pure DC) 以及 AC+DC 複合輸出模式。這使受測元件（DUT）能夠針對電力電子系統中常見的非理想運作條件（如非對稱開關切換、整流效應及磁偏置/直流偏磁等）進行熱性能、控制穩定性及保護響應的全面驗證。

從測試台架的角度來看，此功能可針對非理想但符合實際現況的運作環境，實現受控的熱行為評估、控制穩定性分析與保護機制響應測試。

Modular Rack-Mount Architecture with Parallel Scalability

The rack-mount architecture of CORTEX and 3U module size accommodate the integration into standard 19-inch, 42U rack configuration through paralleled connection where ten modules of them together, with each one's power rated at 22 kVA, achieve power expansion up to 220 kVA.

The parallel operation is coordinated via fiber-optic communication that mitigates the degradation of performance as power scales, meanwhile the built-in module redundancy further enhances system reliability for extended high-power test bench operation.

模組化機架式架構與並聯擴充性

CORTEX 採用機架式架構與 3U 模組化尺寸，可整合至標準的 19 吋、42U 機櫃中。透過並聯連接方式，最多可將 10 組模組整合在一起；以單一模組額定功率 22 kVA 計算，系統總功率可擴充至 220 kVA。

並聯運作由光纖通訊（Fiber-optic communication）進行協調，有效減少了功率擴大時可能產生的性能衰減。同時，系統內建的模組冗餘（Module Redundancy）功能進一步提升了系統可靠性，足以支撐高功率測試台架的長時間連續運作。

Built-In Linear and Non-Linear Load Emulation Capabilities

The CORTEX series integrates both linear and non-linear load emulation within a single platform, enabling flexible device-level testing without external load hardware. For linear load testing, it provides up to 12 built-in RLC network models with adjustable parameters, supporting accurate representation of resistive, inductive, and capacitive load characteristics under single-phase and three-phase balanced or unbalanced conditions.

In non-linear load mode, CORTEX can generate typical distorted load profiles, including 2-, 6-, 12-, 18-, and 24-pulse loads, as well as half-wave, leading-edge, and trailing-edge waveforms. An adjustable crest factor from 1.414 to 5 allows engineers to verify DUT performance under non-sinusoidal current conditions. Seamless source–load mode switching further simplifies ATE configuration and enables comprehensive evaluation of power-electronic devices under realistic load behaviors.

內建線性與非線性負載模擬功能

CORTEX 系列在單一平台內整合了線性與非線性負載模擬功能，無需外接負載硬體即可實現靈活的元件級測試。在線性負載測試方面，系統提供多達 12 組內建 RLC 網路模型，且各項參數均可調節，支援在單相及三相（平衡或不平衡）條件下，精準呈現電阻性、電感性與電容性的負載特性。

在非線性負載模式下，CORTEX 可生成典型的失真負載特性曲線，包括 2、6、12、18 及 24 脈波負載，以及半波、前緣（Leading-edge）與後緣（Trailing-edge）切相波形。其波峰因數（Crest Factor）可在 1.414 至 5 之間調節，方便工程師驗證受測元件（DUT）在非正弦電流條件下的性能表現。無縫的源載模式切換進一步簡化了自動測試設備（ATE）的配置，並能針對電力電子設備在真實負載行為下的表現進行全面評估。

Power Hardware-in-the-Loop (PHIL) Ready with High Bandwidth Response

Dynamics, power amplifications, and interface integration capabilities are what matter for Power Hardware-in-the-Loop (PHIL) testing scenarios. CORTEX is characterized by its capability of offering 10 kHZ small signal bandwidth and 2 kHZ for large signal one, with a fast response time of 70 μs only, which are advanced specifications that achieve the accurate real-time power amplification between digital simulations or controllers and the DUT.

With continuous output capability from DC up to 5 kHz, CORTEX supports realistic reproduction of fast voltage variations, dynamic load interactions, and transient electrical events. Testing applications and scenarios, especially where the control algorithms and hardware are built on the foundation of 400 Hz systems, may benefit from CORTEX's high-dynamic and response feature for laboratory and industrial power testing platforms and environments.

具備高頻寬響應：支援電力硬體在環 (PHIL) 測試

在電力硬體在環（Power Hardware-in-the-Loop, PHIL）測試場景中，動態特性、功率放大能力與介面整合能力是衡量系統優劣的關鍵。CORTEX 具備卓越的技術規格，提供高達 10 kHz 的小訊號頻寬與 2 kHz 的大訊號頻寬，且響應時間僅 70 μs。這些頂尖規格確保了數位模擬器（或控制器）與受測元件（DUT）之間，能夠實現極其精準的即時功率放大。

憑藉從直流（DC）到 5 kHz 的連續輸出能力，CORTEX 能夠真實重現快速電壓變動、動態負載交互作用以及暫態電力事件。對於基礎架構建立在 400 Hz 系統（常見於航空、軍事領域）上的控制演算法與硬體開發，CORTEX 的高動態與高響應特性，將為其實驗室及工業電力測試平台提供極大的技術優勢。

Built-In Standard Waveforms for Compliance-Oriented Testing

CORTEX AC integrates a library of predefined standard waveforms directly into its control interface, allowing test engineers to execute regulation-referenced test profiles without manual waveform construction. These built-in waveforms streamline test setup, reduce configuration errors, and improve repeatability across laboratory and production environments.

In addition to standard selections, CORTEX supports user-defined waveform programming through List, Wave, Step, Pulse, and Advanced modes, enabling flexible sequencing and customization up to 100 harmonic orders. Both application-specific and compliance-oriented testing scenarios have their test bench setup process practically facilitated with the combination of ready-to-use standards and advanced programmability options.
