基于矢量分解和叠加原理的双三相感应电机在全调制比范围内的PWM策略
The PWM Strategy in Full Modulation Region for Dual Three-phase-induction Motors Based on Vector Decomposition and Superposition Principle
摘要
Abstract
To increase the utilization ratio of the DC bus voltage and eliminate the current harmonics,a novel space vector pulse width (SVPWM) modulation technique was presented for a dual three-phase induction motor fed with six-leg voltage source inverter.Based on the vector decomposition algorithm,the reference voltage vector was calculated on the fundamental subspace where the low order harmonics are eliminated.To realize smooth transitions from linear modulation to six-step operation,the proper switching state vectors were chosen according to superposition algorithm to recompose the reference voltage vector in over modulation section.The pulse width modulation (PWM) modulation strategy in full region was described in detail.The experimental results show that the amplitude of fundamental voltage is proportional to the modulation factor and the harmonics of stator currents are obviously reduced.关键词
