關(guān)于二極管反向恢復(fù)時(shí)間問題?
當(dāng)用二極管進(jìn)行整流時(shí),除考慮他的功率和耐壓值外,還要考慮他的反向恢復(fù)時(shí)間,請(qǐng)問各位大俠,什么什么反向恢復(fù)時(shí)間啊?為什么要考慮他的反向恢復(fù)時(shí)間呢?請(qǐng)告知,謝謝!!!!

Trr
Trr:Another parameter which can be used to determine the
speed of the rectifier is the reverse recovery time (trr ). This
is measured from the instant the current passes through
zero (from forward to reverse) to the instant the current
recovers to either 10% or 25% of its peak reverse value.
Low reverse recovery times are associated with low
stored charge devices.
