High Performance ASIC Circuit for a Three-Phase Controlled Bridge Fed Static or Dynamic Load

Summary

The increasing availability of single chip low cost Integrated Circuits has made it possible to reconsider conventional hardware designs for a variety of gating circuits. This paper presents a high performance Application Specific Integrated Circuit ASIC’s for a three-phase controlled bridge. The dynamic performance of the proposed ASIC is similar to an analog circuit implementation. The resolution of the firing angle is better than 0.043 degrees at 50 Hz. The good dynamic performance was verified by operating a six pulse bridge with the designed ASIC circuit and different firing angles. The bridge was supplying d-c voltage to R-L load or D-C motor. The test result (input a-c phase currents, d-c load current and d-c load voltage) confirm the excellent dynamic performance.
