It is shown that the decrease of this parameter and the decrease of the Miller plateau level result in a decrease of the collector current rise-time, the collector鈥揺mitter voltage fall-time, the turn-on switching energy and in an increase of the peak of the turn-on switching instantaneous...
Wide-band-gap power devices hold great promise for creating power-conversion systems that are smaller, faster and more energy efficient than silicon power devices. Benefiting from smaller parasitic capacitors and superior conductive characteristics of gallium-nitride (GaN) transistors, the switching frequen...
The third choice is not encouraged due to possible oscillation after the turn-on switching transition. This is because after the switching transition is finished, the energy stored in the trace inductor will oscillate with the junction capacitance of the diode to dissipate the energy. Therefore, a...

Step 3. Opt for "Energy Saver"; this icon resembles a light bulb.Step 4. Tick the checkbox adjacent to "Prevent computer from sleeping automatically when the display is off".Step 5. Uncheck the box by the side of "Put hard disks to sleep when possible".Step 6. Lastly, turn the ...
my Samsung Galaxy tab A switches on automatically when you plug it to a power supply and when you switch it off still it will switch on without switching it on. in other words I can not charge it will it is off and it’s been three months now. How can I get help Isaac says: Mar...
discharge cycle the switching transistor214is turned on, charging the ignition coil210for a specified dwell period or to a specified charge current; and then the switching transistor214is turned off, allowing the secondary side218of the ignition coil210to discharge stored energy across the spark ...
