I was tasked by one of my professors to create a device to change the direction of current flow through a solenoid in order to change the direction of the magnetic field it produces. He gave me a partially completed H-Bridge design using 4 MOSFETs which I completed and told me to drive them using a HIP4081A. However, the whole thing is supposed to be driven by a square wave from a function generator and I am unsure how to make the inputs of the HIP4081A work with this since normally the BLI and ALI are inverted versions of each other.
H-Bridge schematic the load (M) would be a coil to act as a magnet.
My current design is using diodes to rectify the square wave into the positive amplitudes and the negative amplitudes. My main problem is that I would then need to make the negative amplitudes positive to have out of phase inputs into ALI and BLI (i.e. ALI high while BLI is zero and vice versa) and I am not really sure how to do this.
If there is also a better way to do all of this let me know.
Note: I also have BHI and ALI sharing the same input and BLI and AHI sharing the same input.
I have uploaded the datasheet for the HIP4081A.
This is my first post and I am a physics student so I don't know a whole lot about this kind of stuff so go easy on me.
