Hi,
I am having the problem in the input of the MOsfet driver.
MOsfet driver input is coming through some logic gates, till the logic gates (NOR)the output is 12V pulse but when i give it to the Mosfet driver input, it goes low to 1V. which is not enough for my Mosfet driver. Why it's going...
My circuit is more less like this;
The timer will set the 180us pulse, then we have a driver for the mosfets switches and that give path to the transformer when they are in "ON" states.
The threads you mentioned above is already solved. thank you for your guidance:)
The idea is, we don't want to use a separate power supply of 300V for this purpose. I want to step up the voltages from 30 to 300.
First, i thought i can make a pulse transformer for this but then i realized...
Thank you very much for your time. This is very helpful information.
Could you please guide me that how can i design the primary number of turns. if i want to step up the voltage from 30V to 300V ?
Hello,
How can i calculate a ferrite core transformer primary number of turns, if i have a variable frequency pulse at the input of the transformer.
My frequency range is 0.1 HZ to 250 HZ.
How can one design a variable frequency transformer. ??
Your help will be appreciated.
Thank you
I got your point. could you please tell me that how can i switch the two voltages by using floating gate driver?
The problem, i am facing is floating point. For 300V, i have ground terminal but for the 9V, there is no ground it's floating.
shown below is image, what i got from your point...
Thank you very much for your help.
Could you please explain a bit more, where should i insert the series resistor of 600ohm. If i put in series with the load than high percentage of voltage drop is across the this 600ohm resistor not across my load (valve).
If i put like in your way than i...
After the 180µs, the current is same because it's connected to another voltage supply of 9V. Valve is operating correctly, don't worry about the valve operation.
Could you please tell me, how to design that Rd resistance of the mosfet in the shunt load scenario.
The question is how can i design the rd resistance of the mosfet, as i have a shunt load connection (74ohm resistance).
1)when the mosfet is ON, there would be 300V for the shunt load only for 180microseconds.
2) when the mosfet is OFF, there would be 0V for the shunt load for the rest of the...
