[help with producing a current waveform]

hello indulis,
  is there any other way to obtain such a triangular waveform like using IGBT or any other power electronic device . the current will be in the range of a few tens of amperes

    at present i am applying a triangular drive pulse to the gate V_GS but my current I_D , the drain current is not following that waveform.
the control voltage i am applying is only 0-5 V .
       
      My main requirement is to produce a current pulse of a high rating . in my circuit this triangular current pulse would be utilised by a EDMT machine
         
     

[help with producing a current waveform]

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

______2 ohm_______
