Hence, it must be avoided through both robust board design and proper switching control, as discussed in Section 3 Key for a robust configuration. Radiated Electric field In switching circuits, charges are continuously redistributed among various nodes, thus travelling from a point to a...
Now this current amplification task is performed by the power stage . In this stage two N-Mosfets are configured in push-pull topology to amplify the current. Mosfet Chosen are IRF3205 Step 3: TRANSFORMER Now this is very simple, the output waveform from the pushpull topology is fed into th...

releasing the induced energy to protect the MOSFET, if necessary , Can also add RC snubber circuit (Snubber) to suppress voltage spikes. (Note that the diode direction should not be reversed. Of course, you can also directly choose a MOSFET with a large enough VDS, provided that you do no...
I will have to see the schematic diagram of your design to understand the problem. So, if possible please send the schematic diagram to my email ID, I will try to figure it out for you. Reply Robertsays July 15, 2024 Dear Sir, ...
This should work well for voltages up to 60v before the MOSFET's should be changed as well... I heard that some people had operated their ZVS driver at voltages over 100, just imagine how massive their arcs must be! Also, this ZVS driver circuit does not have be used just for the fl...
MOSFET in the same D2PAK-3L package, which is documented has having an Rds(on) of 45 milliohms maximum (40 typical). On first impressions it may appear that the SJ device is better, especially as its maximum drain current at 25°C is 46A (compared with just 41A for the SiC FET...
Figure 4The primary switch node is MOSFET’s drain-to-source voltage. Source: Texas Instruments Influence of transformer leakage inductance Now that you’ve seen how overshoot can have a detrimental effect on cross-regulation for light loads, the question arises: Why don’t you just clamp it ...
