摘　　要：提出了PWM变换器的相位补偿谐振控制方案。借助于重复控制的相位补偿原理,阐明了谐振控制的相位补偿原理,建立了相位补偿重复控制与相位补偿谐振控制之间的有机联系。相比于相位补偿重复控制器,相位补偿谐振控制器能够独立地对任意的谐波频率提供所需的相位补偿,以期实现"零相位"补偿,从而能扩大稳定范围;同时,根据各谐波含量的大小,能相应地选取各谐振控制器的增益去优化系统性能,并提供了一个单相PWM逆变器的应用实例,系统地验证了所提方案的有效性。In this paper, phase compensation resonant control scheme is proposed for PWM converters. With the help of the phase compensation principle of repetitive control, the phase compensation principle of resonant control is illustrated and the organic link is build between phase compensation repetitive control and phase compensation resonant control. Compared with phase compensation repetitive controller, phase compensation resonant controller can independently provide required compensation phase at any harmonics to expectably achieve ＂zero phase＂ compensation, and the stable range is thus expanded. Moreover, according to the magnitude of each harmonic, the gain of each resonant controller can be correspondingly selected to optimize system performance. An application example of single-phase PWM inverter is provided to systematically demonstrate the effectiveness of the proposed control scheme.
