Driver circuit
The main purpose of driver circuit is we have to enhance the swithching voltage for the mosfet or any
switching device.And also we have to isolate the power circuit from the icrocontroller circuit.Because
the power circuit current must not enter into the microcontroller circuit.MCT2E is the optocoupler
which will be connected to the buffer CD4050 which send pulse signals of 5 v from microcontroller to
the driver circuit.MCT2E is the device which isolates the power circuit with the microcontroller
circuit.After it gets the signal from thre microcontroller it will get enhanced using the 2N2222 transistor
to higher level of voltage .after this the voltage get regulated by the use of darlington pair.The
darlington is made of 2N2222(NPN) and SK100 (PNP) transistor
