【摘要】 随着大容量、新能源、特殊环境电能变换技术的不断发展,能源行业对三相逆变器的性能指标和可控性的要求也日益苛刻,传统控制方法很难满足实际应用的需要。为此,设计了一种三相逆变器的非相邻模态切换控制方法,在相同的载波频率下,该控制方法与传统空间矢量脉冲宽度调制(SVPWM)算法相比具有更低的开关频率,从而可以有效降低系统功耗,提高系统效率。仿真及实验证明该新型控制策略的有效性与可行性。更多还原

【Abstract】 With the development of power conversion technologies with large capacity,new energy and special environmental,stronger controllability and better performance of the three-phase inverter is demanded by the energy industry,hence,traditional control methods is too difficult to meet the needs of practical application.Therefore,a novel control strategy named switching control with non-adjacent vectors is proposed in this paper.It shows that,at the same carrier frequency,the novel control strategy has a lower switching frequency compared to the traditional space vector pulse width modulation(SVPWM) algorithm,which can effectively reduce system power consumption to improve system efficiency. Simulation and proved the effectiveness and feasibility of the newcontrol strategy.更多还原
