尤其是微处理器应用于PWM技术并使之数字化以后，花样是不断翻新，从***初追求电压波形的正弦，到电流波形的正弦，再到磁通的正弦；从效率，转矩脉动***少，再到消除噪音等，PWM控制技术的发展经历了一个不断创新和不断完善的过程。到目前为止，还有新的方案不断提出，进一步证明这项技术的研究方兴未艾。其中，空间矢量PWM技术以其电压利用率高、控制算法简单、电流谐波小等特点在交流调速系统中得到了越来越多的由于。LS产电，可编程控制器，变频器，输入输出模块，欢迎咨询，在小功率交流调速方面，由于国外产品的规模效应，使得国内厂家在价格上、工艺上和技术上均无法与之抗衡。而在高压大功率方面，国外公司又为我们留下了赶超的空间。首先，国外的电网电压等级一般为3000V，而我国的电网电压等级为6000V和10000V；其次，高压大功率交流调速系统无法进行大规模的批量生产，而国外的劳动力成本，特别是具有一定***知识的劳动力成本较高。目前，研究较多的大功率逆变电路有：（1）多电平电压型逆变器，（2）SV004iG5-1变压器耦合的多脉冲逆变器，（3）交交变频器，（4）双馈交流变频调速系统。K7M-DR10SABS-62b60251053ABS-63b4ABS-64b1002ABS-102b15,20,30,40,50,60,75,1005025103ABS-103b4ABS-104b2252ABS-202b100,125,150,175,200,2255025103ABS-203b4ABS-204b4002ABS-402a250,300,350,4005035223ABS-403a4ABS-404a6002ABS-602a500,60010050353ABS-603a4ABS-604a8002ABS-802a700,80010050353ABS-803a4ABS-804a10003ABS-1003100010065454ABS-100412003ABS-1203120010065454ABS-120(AF)极数MCCB额定电流(A)额定分断能力(kA)220V460V600V302ABS-32b(3),5,10,15,20,302.51.5-3ABS-33b2ABE-32F3,5,10,15,20,302.51.5-ABE-33F502ABS-52b5,10,15,20,30,40501052.53ABS-53b4ABS-54b2ABE-52F15,20,30,40,502.51.5-3ABE-53F602ABS-62b601052.53ABS-63b4ABS-64b1002ABE-102F60,75,10051.5-3ABE-103F2252ABS-202b100,125,150,175,200,22535187.53ABS-203b4ABS-204b4002ABS-402a250,300,350,4003525183ABS-403aSV004iG5-14ABS-404a6002ABS-602a500,6005035223ABS-603a4ABS-604a8002ABS-802a700,8005035223ABS-803a4ABS-804a普通型塑壳用断路器(高分断容量型)框架(AF)极数MCCB额定电流(A)额定分断能力(kA)220V460V600V302ABS-32b5,10,15,20,30251053ABS-33b502ABS-52b15,20,30,40,505025103ABS-53b4ABS-54b1002ABS-102b15,20,30,40,50,60,75,1006535183ABS-103b4ABS-104b2252ABS-202b100,125,150,175,200,2256535183ABS-203b4ABS-204b4002ABS-402a250,300,350,4008550303ABS-403a4ABS-404aHi-MEC系列产品框架(AF)极数MCCB额定电流(A)额定分断能力(kA)220V460V600V2252ABS-202b125,150,175,200,2258542253ABS-203b4ABS-204b普通型塑壳断路器(限流型)(AF)极数MCCB额定电流(A)额定分断能力(kA)220V460V600V502ABS-52b15,20,30,40,5010065353ABS-53b4ABS-54b1002ABS-102b15,20,30,40,50,60,75,10010065353ABS-103b4ABS-104b2252ABS-202b125,150,175,20022512565353ABS-203b4ABS-204b4002ABS-402a250,300,350,40012565353ABS-403a4ABS-404a6002ABS-602a500,60012565423ABS-603a4ABS-604a8002ABS-802a700,80012565423ABS-803a4ABS-804a10003ABS-1003100010085654ABS-100412003ABS-120312001258554ABS-1204K7M-DR20SK7M-DR30SK7M-DR40SK7M-DR60SK7M-DR10S/DCK7M-DR20S/DCK7M-DR30S/DCK7M-DR40S/DCK7M-DR60S/DCK7M-DT10SK7M-DT20SK7M-DT30SK7M-DT40SK7M-DT60SG7E-DR10AG7E-DT10AG7F-ADHAG7F-AD2AG7L-CUECG7L-CUEBG7F-AT2AG7F-RTCAG7M-M256K3P-07ASK3P-07BSK3P-07CSGM6-PDFAGM6-PDFBGM6-PAFAGM6-PAFBGM6-PAFCG6I-D21AG6I-D22AG6I-D24AG6I-D22BG6I-D24BG6I-A11AG6I-A21AG6Q-RY1AG6Q-RY2AG6Q-TR2AG6Q-TR2BG6Q-TR4AG6Q-TR4BG6Q-SS1AGM6-B04MGM6-B06MGM6-B08MGM6-B12MG6F-AD2AG6F-DA2VG6F-DA2IG6F-HSCAG6F-POPAG6F-PP1DG6F-PP2DG6F-PP3DG6F-PP1OG6F-PP2OG6F-PP3OG6F-TC2AG6F-CUEBG6F-CUECG6L-FUEAG6L-RBEAGOL-***IAGOL-***QAGOL-***HAGM6-DMMAK4P-15ASGM4-PA1AGM4-PA2AGM4-B04MGM4-B06MGM4-B08MGM4-B12MGM4-B04EGM4-B06EGM4-B08EG4M-M032G4C-E041G4C-E121G4C-E301G4I-D22AG4I-D24AG4I-D22BG4I-D24BG4I-A12AG4I-A22AG4Q-RY2AG4Q-TR2AG4Q-TR4AG4Q-TR8AG4Q-TR2BG4Q-TR4BG4Q-SS2AG4Q-SS2BG4H-DR2AG4H-DT2AG4F-INTAG4F-AD2AG4F-AD3AG4F-DA1AG4F-DA3VG4F-DA2VG4F-DA3IG4F-DA2IG4F-TC2AG4F-RD2AG4F-AT3AG4F-PIDAG4F-HSCAG4F-PP1DG4F-PP2DG4F-PP3DG4F-PP1OG4F-PP2OG4F-PP3OG4F-POPAG4F-POPBG4L-CUEAG4L-FUEAG4L-RBEAGOL-***IAGOL-***QAGOL-***HAGM4-DMMAK7P-30SGM3-PA1AGM3-PA2AGM3-B04MGM3-B06MGM3-B08MGM3-B04EGM3-B06EGM3-B08EG3C-E061G3C-E121G3C-E301G3M-M064SG3I-D22AG3I-D24AG3I-D28AG3I-A12AG3I-A22AG3I-D22CG3I-A14AG3I-A24AG3Q-RY2AG3Q-SS2AG3Q-TR2AG3Q-RY4AG3Q-SS4AG3Q-TR4AG3Q-TR4BG3Q-TR8AG3Q-TR8BG3F-INTAG3F-AD3AG3F-AD4AG3F-AD4BG3F-DA3VG3F-DA3IG3F-DA4VG3F-DA4IG3F-PA1AG3F-PA2AG3F-AT4AG3F-PIDAG3F-HSCAG3F-POPAG3F-POAAG3F-T***AG3F-RD3AG3L-CUEAG3L-FUEAG3L-RBEAG3L-FUOAG3L-RBOAG3F-DMMAK7M-DR10SK7M-DR20SK7M-DR30SK7M-DR40SK7M-DR60SK7M-DR10S/DCK7M-DR20S/DCK7M-DR30S/DCK7M-DR40S/DCK7M-DR60S/DCK7M-DT10SK7M-DT20SK7M-DT30SK7M-DT40SK7M-DT60SG7E-DR10AG7E-DT10AG7F-ADHAG7F-AD2AG7L-CUECG7L-CUEBG7F-AT2AG7F-RTCAG7M-M256K3P-07ASK3P-07BSK3P-07CSGM6-PDFAGM6-PDFBGM6-PAFAGM6-PAFBGM6-PAFCG6I-D21AG6I-D22AG6I-D24AG6I-D22BG6I-D24BG6I-A11AG6I-A21AG6Q-RY1AG6Q-RY2AG6Q-TR2AG6Q-TR2BG6Q-TR4AG6Q-TR4BG6Q-SS1AGM6-B04MGM6-B06MGM6-B08MGM6-B12MG6F-AD2AG6F-DA2VG6F-DA2IG6F-HSCAG6F-POPAG6F-PP1DG6F-PP2DG6F-PP3DG6F-PP1OG6F-PP2OG6F-PP3OG6F-TC2AG6F-CUEBG6F-CUECG6L-FUEAG6L-RBEAGOL-***IAGOL-***QAGOL-***HAGM6-DMMA)
