33、科领域，是目前电力电子产业和科研的热点之一。逆变电源广泛应用于航空、航海、电力、铁路交通、邮电通信等诸多领域。逆变电源的发展是和电力电子器件的发展联系在一起的，器件的发展带动着逆变电源的发展。逆变电源出现于电力电子技术飞速发展的20 世界 60 年代，到目前为止，它经历了三个发展阶段。第一代逆变电源是采用晶闸管（SCR）作为逆变器的开关器件称为可控硅逆变电源。可控硅逆变电源的出现虽然可以取代旋转型变流机组，但由于 SCR 是一种没有自关断能力的器件，因此必须增加换流电路来强迫关断SCR，但换流电路复杂。噪声大、体积大、效率低等原因却限制了逆变电源的进一步发展。第二代逆变电源是采用自关断器件作为
34、逆变器的开关器件。自20 世纪 70 年代后期，各种自关断器件想运而生，它们包括可关断晶闸管（GTO）、电力晶闸管（GTR）、功率场效应管（MOSFET）、绝缘栅双极性晶体管（IGBT）等。自关断器件在逆变器中的应用大大提高了逆变电源的性能第三代逆变电源实时反馈控制技术，使逆变电源性能得到提高。实时反馈控制技术是针对第二代逆变电源非线性负载适应性不强及动态特性不好的的缺点提出来的，它是最近十年发展起来的的新型电源控制技术，目前仍在不断完善和发展之中，实时反馈控制技术的采用使逆变电源的性能有了质的飞跃1.2 设计思想本设计所需单相正弦波SPWM 逆变电源的设计采用了运算放大器、二极管、功率场效应
