Abstract
This paper presents the design of a digital control IC which is intended for controlling thyristors to produce a constant current source via a three-phase controlled rectifier. The architecture of the digital control IC consists of three major parts: a three-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 linked with ModelSim for verification the function of control circuit in the Simulink, ModelSim and PSIM cosimulation environment. The designed digital control IC has been implemented on an Altera Flex 10K FPGA logic device. Simulation and experimental results are shown to verify the viability of the proposed digital control IC properly.
