碩士 === 國立成功大學 === 電機工程學系碩博士班 === 96 === This thesis presents the system modeling and analysis of the single-phase and the interleaved four-phase current regulation modules, for use in the electrical discharge machine. With the derivation and validation of the open-loop transfer functions for the single-phase and the interleaved four-phase current regulation modules, the system characteristic analysis and the compensator design have been developed. Based on the equivalent circuit models of the three-terminal PWM switching cell, the small-signal models of the single-phase and the interleaved four-phase current regulation modules have been proposed to compared with the SIMPLIS® simulation results. Moreover, the compensator has been designed in order to obtain sufficient DC gain, bandwidth, gain margin, and phase margin for the interleaved four-phase CCM CRM by utilizing the derived open-loop transfer functions. Finally, the Gain/Phase measurement station has been built by using the PSM1735, Gain/Phase Analyzer, to validate the derived open-loop transfer functions for the system characteristic analysis.
