本文提出一個單相相控整流器電流源其數位控制IC之設計，可利用此控制IC控制相控整流器之閘流體以產生一個定電流源，其內部架構包含三部份，分別為：一個單相相位控制的觸發電路、一個反餘弦計算查值表及一個比例積分電流控制器，此三部分之電路設計是以VHDL語言來實現，可做為整個相控整流器電流與相位觸發控制之智財，設計後並在Simulink和ModelSim的共同模擬環境下，建立此單相相控整流器電流源之模型以進行模擬驗證。此外，電流回授採用多重取樣平均值的方法，以減少電流漣波的影響，最後下載到一個Altera Flex10K FPGA邏輯元件進行實驗，模擬與實驗結果顯示此控制IC的可行性。

This paper presents the design of a digital control IC which is intended for controlling thyristors to produce a constant current source via a single-phase controlled rectifier. The architecture of the control IC consists of three major parts: a single-phase controlled triggering circuit, an inverse cosine look-up table, and a proportional-integral current controller. All the three parts have been designed using VHDL language and integrated as a control IP (intellectual property). The simulation model for a constant current source based on a single-phase controlled rectifier has also been constructed by using Simulink and ModelSim cosimulation tool. Further, a multiple-sampling and average scheme for the current feedback has been adopted to reduce the current ripple effect. The designed control IC circuit has been implemented on an Altera Flex 10K FPGA logic device. Simulation and experimental results are shown to verify the viability of the proposed control IC properly.
