hello everyone,
thanks in advance for taking the trouble to read and reply
i am struck with a circuit here . i am aiming to produce a triangular current waveform which has to be used in a different circuit . i've given the simplified version of the circuit
max current 10A , frequency 10 KHz
i am currently using MOSFET IRFP 250N. my gate drive voltage is a 5 V variable supply given from my computer(Vgs)
i am getting a linear current (Id) output when gate supply in the range of 3.5 to 3.9 and then it is suddenly shooting up and after that i am again getting a linear variation . This results in the distortion of my current waveform and so i am not able to implement it in my other circuitry
could you please help me with this problem or is there any other way to produce such a pulse like using IGBT or any other power device . please help
