一提正弦波逆变器,大家首先想到SPWM技术.如何实现SPWM呢?肯定很多人的第一想法是使用单片机.的确,使用单片机的好处不少:SPWM波精度高,输出正弦波波形好,稳压精度高,方便加入电压指示功能等,单...

传统的交流调压器-自藕变压器,缺点显而易见,沉.......前一段时间我设计了一个纯正弦SPWM驱动板，如果配合此电路没准可以做成无铁心的交流调压器，但是只能降压。调节SPWM板上的圈1电位器实现调压...

[b] 在只有一只山寨万用表，一把电烙铁，一台能上网的电脑，声卡虚拟示波器的条件下。耗时将近一个多月！这台逆变器终于略显雏形了！电路参考的是电源网老寿先生的的《一款纯硬件的SPWM正弦波逆变系统》和《...
