PSEUDO ZERO VECTOR FOR SPACE VECTOR MODULATION AND ENHANCED SPACE VECTOR MODULATION

摘要

PROBLEM TO BE SOLVED: To provide pseudo zero vectors for space vector modulation and enhanced space vector modulation.SOLUTION: A method of performing space vector modulation for PWM control for creating AC waveforms includes generating and sampling a reference signal to generate reference samples, and performing a reference vector approximation to synthesize a reference vector associated with at least one of the reference samples 230. The reference vector approximation employs active vectors, one or more zero vectors, and one or more pseudo zero vectors in the formation thereof. Another method of performing space vector modulation (SVM) includes generating a reference signal and sampling the reference signal at a sampling frequency to generate a plurality of reference samples.
