What is the load current? IRF540 isn't suited for 5V gate control, you better use a logic level FET.
For 60 kHz switching, you need a push-pull gate driver.
There are many logic level FETs suitable for 12V 2A. I forgot an important point: The inductive load will destroy the FET if you don't connect a free-wheeling diode.
Not yet in the schematic.I have added a free wheeling diode to inductive load
The gate driver is connected wrongly. It's a complementary emitter follower, should have NPN on top and PNP on the bottom. Both emitters tied to the gate. No base resistors required, instead an optional low ohmic gate resistor.
Not yet in the schematic.
In scope, channels should be set to DC measurement. In your setup, all channels are set to measure AC.
So, what kind of waveform are you expecting to have on inductive load? Perfect square?
Yes, more or less.Yes, my requirement is perfect square at the output at 60Khz.
Is it possible...?
Yes, more or less.
Thanks,
But how can i do it. is my circuit diagram perfect, or need to do some changes, because while stimulating in proteus its not giving proper output.
do i need to test it in actual hardware using oscilloscope
The schematic is OK although I would add a resistor in series with the input. Your problem is the 11N60DM2 which needs as much as 5V on its gate before it STARTS conducting. Ideally you want far more than that to ensure it turns full on .
The simplest modification I can think of is to connect Q5 collector and R2 to 24V and add another transistor at the input to drive Q5 and Q6.
