MOSFETs require pulses at its gate terminal in order to work and the amount of current going through the source and drain terminals is depend on their characteristics and controlled by magnitude of the gate pulses. Normally, the magnitude of gate pulses is fixed and set to a nearly maximum allowable current can go through it.
The problem with fixed type gate pulses is whenever overload or switching occurs; the MOSFETs will experience high current and may working beyond their safe operating area (SOA) which might destroy the MOSFETs.
The objective of the project is to find a method on how the variable magnitude pulses gate could be implemented.
The project should be able to adjust the amount of current flowing through the MOSFETs from 0A to maximum.
NOTE:
The project will use PIC 16F84A
Did any one have the idea to share regarding this project???
