We are using MOSFET #AIMDQ75R045M1H for our EV chager application. While testing the input stage Totem Pole PFC stage observed flat region in the Vds Voltage during its transition from ON state to Off state. The attched above image represents the switch off of the MOSFET Green col...
These MOSFETs are helpful in switching the negative supply for the motor in the reverse direction. An n-channel MOSFET operates in saturation & cut-off regions. then it acts like a switching circuit. These MOSFETS are used to switch LAMP or the LED to ON/OFF. These are preferred in high ...

Such a switch must, however, ensure that the MOSFET is always operated within its safe operating area (SOA). If this is not the case, the semiconductor and thus the circuit will be damaged. Unfortunately, it’s not always easy to select a suitable MOSFET and operate it in just such a ...
The gate is equivalent to a gate (switch) VG is bigger than the VT tube conduction, the source is the place where the electrons come from, and the drain is the place where the electrons disappear (leak). 3. Why do mos tubes need gate drive circuits? The MOS tube is driven by voltag...
The switch again turns on at the beginning of the next clock pulse. The capacitor voltage v and the inductor current i are the state variables of the circuit. The boost converter operating in continuous mode is described by two sets of linear differential equations as: Figure 1. Block ...
side now has a lower output by pulling the end down through the open drain. The MOSFET’s drain-substrate diode substrate is pulled down (as seen in the MOSFET schematic) so that it can flow from the source to the drain (opposite to the conducting current, when it works as a switch)...
