style="text-indent:25px">電子變壓器除了體積較小外，在電力變壓器與電子變壓器二者之間，并沒(méi)有明確的分界線。一般提供60Hz電力網(wǎng)絡(luò)之電源均非常龐大，它可能是涵蓋有半個(gè)洲地區(qū)那般大的容量。電子裝置的電力限制，通常受限于整流、放大，與系統(tǒng)其它組件的能力，其中有些部份屬放大電力者，但如與電力系統(tǒng)發(fā)電能力相比較，它仍然歸屬于小電力之范圍。各種電子裝備常用到變壓器，理由是：提供各種電壓階層確保系統(tǒng)正常操作;提供系統(tǒng)中以不同電位操作部份得以電氣隔離;對(duì)交流電流提供高阻抗，但對(duì)直流則提供低的阻抗;在不同的電位下，維持或修飾波形與頻率響應(yīng)。「阻抗」其中之一項(xiàng)重要概念，亦即電子學(xué)特性之一，其乃預(yù)設(shè)一種設(shè)備，即當(dāng)電路組件阻抗系從一階層改變到另外的一個(gè)階層時(shí)，其間即使用到一種設(shè)備-變壓器。對(duì)各種類型變壓器可實(shí)現(xiàn)快速準(zhǔn)確測(cè)量，具有操作簡(jiǎn)便、精度高、抗干擾等特點(diǎn)。</p><div
