    Abstract: 本文主旨在於研製一個軌道牽引變流器相位模組之測試
    系統,由切換式整流器與雙向dc-dc轉換器建構成此一測試系
    統。藉著使用脈波寬度調變(PWM)技術,使得該測試系統
    提供給待測相位模組一個與實際使用相同之電氣環境。在這些
    情況下,待測相位模組的介電與導電能力可以被估測出來,而
    不需煩雜的實測。為了改善測試系統的功率品質,前級的切換
    式整流器提供了直流鏈電壓。後級雙向dc-dc轉換器是由降壓
    式與升壓式轉換器串聯而成,其功能如用一個可控的交流電流
    源來做導電的測試,且只有少量的功率消耗。本文中謹慎的計
    算分析系統中各個元件的效率和功率消耗。經由模擬與實作的
    結果可證明本文所提出的測試系統的可行性,且測試的規格為
    電壓1000 伏特、電流10 安培。
    The purpose of this paper is to implement a testing system
    of phase modules which are used in railway traction inverters.
    The proposed testing system is composed of a switch-mode
    rectifier(SMR)and a bidirectional dc-dc converter. By using
    pulse-width-modulation technique, the testing system provides
    electrical conditions that are simular to real operation for the
    under-tested phase modules. Under these conditions, the dielectric
    and conducting capabilities of the under-tested phase modules can
    be assessed without troublesome field test. To improve the power
    quality of the testing system, a single-switch SMR is deploied at
    the front stage which provides the dc link voltage. Cascading a
    buck and a boost converters to form a bidirectional dc-dc
    converter, the second stage works as a controllable ac current
    source for the conducting testing with only few power
    consumption. For evaluating system efficiency, consumption of
    each element is analyzed carefully in this thesis. Both simulation
    and experimental results are shown in this thesis to verify the
    validity of the proposed testing system. The testing specification
    of this system is based on the voltage of 1000V and the current of
    10A.
