                          详解MOS管发热的可能性原因

                          摘要:论N型或者P型MOS管,其工作原理本质是一样的。MOS管是由加在输入端栅极的电压来控制输出端漏极的电流。MOS管是压控器件它通过加在栅极上的电压控制器件的特性,不会发生像三极管做开关时的因基极电流引起的电荷存储效应。

                            无论N型或者P型MOS管,其工作原理本质是一样的。MOS管是由加在输入端栅极的电压来控制输出端漏极的电流。MOS管是压控器件它通过加在栅极上的电压控制器件的特性,不会发生像三极管做开关时的因基极电流引起的电荷存储效应,因此在开关应用中, MOS管的开关速度应该比三极管快。其主要原理如图:图1。
