Each and every power semiconductor device having a specific
range of switching frequency or operating frequency. it
depends upon manufacturing. in datasheet, i will be given.
Depends upon the input voltage, current or power and
frequency, we should choose the device.
eg., for low frequency and high power circuits, SCRs are
preferred.for low power and high frequency, IGBTs,GTOs are
preferred.
