详情描述：

（1）电压型变频器
电压型变频器特点是中间直流环节的储能元件采用大电容，负载的无功功率将由它来缓冲，直流电压比较平稳，直流电源内阻较小，相当于电压源，故称电压型变频器，常选用于负载电压变化较大的场合。
（2）电流型变频器
电流型变频器特点是中间直流环节采用大电感作为储能环节，缓冲无功功率，即扼制电流的变化，使电压接近正弦波，由于该直流内阻较大，故称电流源型变频器（电流型）。电流型变频器的特点（优点）是能扼制负载电流频繁而急剧的变化。常选用于负载电流变化较大的场合。

法国作家儒勒?米什莱在他的一篇文章中写到：“阳光使在黑暗中追逐我们的恐怖却步，使梦幻的烦恼和痛苦消失，使困扰灵魂的骚乱思绪逃遁得无影无踪。”的确，任何人在阳光下都会有一种安全感，都会保持一种愉快的心情，都会留恋自己生活着的这个世界，并由此变得可爱和令人尊重。我喜欢阳光，自然更喜欢冬天的阳光。
