摘要
针对单相大功率宽频带低失真逆变器这一特殊要求 ,介绍了SPWM多重化 (MSPWM)技术。调制频率在 3Hz～ 5kHz的宽频带内 ,可使输出总谐波失真小于 1% ,单元容量可达 4kVA。使用二次多重化方法 ,可使总容量增大时的同时减小谐波失真。给出了仿真和实验结果。
Aiming at the single phase power inverter with wide band and low distortion, the multiple SPWM(MSPWM) technique is introduced. When the modulating frequency is in the range of 3Hz to 5kHz and the output total harmonic distortion of a 4kVA device is less than one percent. Using a further multiple method the total capacity of the device can be increased and the distortion is decreased at the same time. Simulation and experiment results are give in this paper.
