In the case of the MOSFET transistor, this value may be assimilated to a simple resistance in the ON state, written RDSon in manufacturer documentation. Consequently, the power dissipated by conduction is written simply: [2.2]Pcond=α.RDSon.I2 2.1.2 Notion of switching loss Switching losses ...

The PWM frequency is also a determinant of the cross conduction losses because it will determine the time window for each MOSFET to turn off. When cross conduction occurs, the losses will be proportional to (in 1st order approximation): Loss ∝ (switching frequency)*(switching time) Switching ...
Buck or Boost DC / DC converters synchronous rectification MOSFET is operated as a current source, instead of being turned off, thereby reducing the undesirable loss of efficiency, undesirable electronic noise generation and radiation, as well as many other potential problem, especially when the ...
While this energy increases the thermal vibrations of the silicon atoms (producing increased atom-electron scattering), any loss in electrical conductivity due to this phenomenon is swamped by the increase in electrical conductivity due to the thermal promotion of electrons from the valence to the ...
