方案概述

近(jin)些年(nian)來(lai),隨著電(dian)(dian)子(zi)技(ji)術的不斷(duan)發展和廣泛運用,手持式電(dian)(dian)動(dong)工(gong)具(ju)的技(ji)術越來(lai)越成熟,在(zai)追求卓越性能的同時(shi),各(ge)國對其電(dian)(dian)磁(ci)兼容要(yao)求越來(lai)越高,相對應的標準(zhun)也在(zai)不斷(duan)地更新和完善,產品認(ren)證(zheng)認(ren)可的門檻(jian)越來(lai)越高。很有必要(yao)對電(dian)(dian)動(dong)工(gong)具(ju)電(dian)(dian)磁(ci)干擾進行研究,提出一些抑(yi)制(zhi)方法(fa)。
