For example, in motor drive inverts it is not unusual to select a MOSFET with V(BR)DSS rating of twice the DC bus voltage. It is, however, a mistake to choose a part with a higher rating than needed, because this would give a higher RDS(on) and probably cost more. Methods that ...
A coupled-electro-thermal RDS(ON) (drain to source ON resistance) co-analysis methodology for Power MOSFET is proposed. The methodology contains two functional modules: 1) physical field solvers and 2) equivalent circuit/network solver. The field solver resolves the electrical and thermal field ...

For t > t2, the switching losses are negligible because the MOSFET is in the ohmic zone, with a constant RDS(on). The charge amount QG,SW = QGD + QGS2 is needed to turn on the FET: it is also called "switching charge". The high-side FET switching losses (for a sing...

Power MOSFET is the semiconductor electronic switch that allows, during the conduction, a very significant reduction of power loss compared to the diodes. The MOSFET has a very low drain-source resistance (RDS,on) during conduction which can be a few tens of milliohm or less. The voltage drop...

2. The current increases following an exponential law as a function of the L/R characteristics of the circuit, which are caused by the presence of an inductance, given some resistance due to the layout and the MOSFET ON resistance (RDS(ON)). 3. As soon as the device is switched ...
