Chip Implementation of Digital Scalar Space-vector Pulse Width Modulation for Induction Motor Drive

Abstract This article presents a digital integrated circuit for digital scalar space-vector pulse width modulation in a vector-controlled induction motor drive. All of the blocks, including input stage, calculation, read-only memory, sector decide, sector change, triangular estimation, voltage generator, and voltage transformation vector, are realized in a digital scalar space-vector pulse width modulation integrated circuit as a simple, convenient, high-speed, high-integration and low-cost solution. In the proposed digital scalar space-vector pulse width modulation chip, a feedback trigger signal is utilized to mitigate the problem of asynchronicity, and a four-bit fine tuner is employed to alleviate oscillation at low frequency.
