we want to amplify the amplitude because we discovered something in our simulation. PWM input to an IGBT (we used IGBT to function as a switch w/ PWM as the input to its gate) we plan to let a 220VDC through the transistor and it will be switched on and off through PWM. What we discovered was if our PWM input was only about 5-10Vpp the voltage that the IGBT lets through was approximately 5-10V as well... so we changed the PWM to about 100Vpp and then suddenly the voltage that comes through became 199-215V...
Is this a concept in a transistor?
