The transistor models in the picture are not important, they can be of any other appropriate model as well. Sorry, didnt mean to.. Pulse transformer is a spacial type of transformer for transferring rectangular pulses. BUT many people care about such things and will treat your answers badly if they are not well presented. You don’t have to use both in a circuit. Thank you very much Tahmin I really appreciate your support I am getting to understand about duty cycle. The possible isolaters are:

Thank you I am awaiting your reply. Notice that there are two different high side fet of grounds. Other users may benefit from it. Dynamic IR drop analysis 4. Hello m y friend please remember to explain to me in simple terms the pratical meaning of Duty cycle. And your bootstrap diode has a Vf of 0. Some products also contain on-chip isolated DC-DC converters, so they don’t even need boot-strapping. Are you learning with a goal of entering a high-voltage field?

I have uploaded the circuit please tell me if you see it. You may be adding complications that make learning harder by trying high side fet work on V signals.

The opto-isolator circuit is great and I was hoping to get answers that focus entirely on that part of the driver instead of the general basics of how bootstraps work. In practice, the current they can provide is not enough for driving a MOSFET fast; so they need additional circuitry in practice.

Thank you very much Sidde I really appreciate your support I am getting to understand about duty cycle. Home Questions Tags High side fet Unanswered.

Isolated Gate Driver Isolated gate driving is a relatively new technology. Device with an insulating substrate such as Silicon on Saphiredo not have this intrinsic body diode, but are usually very expensive and specialised. I am getting the v circuit organised i was using sg but I was having some issues of blown ic so I am trying to find a fwt that uses tl as pwm for the high voltage driver but not succesful high side fet if you have a link could you send it to me High side fet you – – – Updated – – – Hello m y friend please remember to explain to me in simple terms the pratical meaning of Duty cycle.


But as soon as the voltages exceed typical Vds and Vgs ratings on transistors, this becomes harder to do. The only difference is I hivh using SG for the pwm for the high voltage inverter insted of tl How is this scheme for multiple solid state relays controlled by a microcontroller?

You can read about Duty Cycle here: I would expect some kind of isolation high side fet to be involved. Originally Posted high side fet narithota.

To achieve such voltages “bootstrap” circuits are often used which usually use a diode capacitor “pump” to give the extra voltage. However, all these super features come with a cost.

The possible isolaters are:
