I am working on a project in which ,
I have to build up a circuit (H-Bridge),with ECU as motor which draws(12V, 10Amps). Analog input to the H bridge done by Myrio (from NI) also to control and alternate switching of H bridge.Motor Cranking is main idea behind making this circuit. The circuit must be able to produce cranking pulse at start up A circuit with few passive components is what i am working on.
2 N-channel MOSFETS and
2-P channel MOSFETS. What other transistor do i need ?
Or a H bridge Driver IC.
The ECU (for eg) which is in place of motor draws some current (10Amps)
Everytime at start-up it is important to have this cranking pulses (test circuit to be made)

 

ECU - Engine C

Or a H bridge Driver IC.

ontrol Unit?

OR would be AND. The p-channel mosfets have to be driven by a higher voltage and the driver provides a bootstrap mechanism to do that. Follow the recommendations of the driver whether series gate resistors are required.

You may need logic FETS which means a Vgs below 5V is enough to turn the mosfets fully on.
You may need resistors to drain the gate charge off so they switch faster.

Some H-bridge controls allow fwd, rev, brake and coast; most allow fwd, rev and coast.
You may need a way to monitor current.

Some H-bridge driers need two sense resistors to monitor both legs and to prevent cross-conduction.

"cranking" in a car also implies that there may be a lower voltage of operation required. e.g 8 V or so, not 12 or 13.8.

Not sure what your asking.

 

I took a oscilloscope to a tractor yesterday and as I turned ON the starter I could see sudden drop in voltages upto 6-7V and so on within 200ms.


This behavior was recorded accordingly in the oscilloscope. The H bridge in the above schematic with Myrio (From NI) ,together have to attain this scenario of cranking once the FET\MOSFET has inputs from Myrio

Similarlly I have to make a LabView code and also GUI for the same..

But at first what components and the circuit design in eagle is important for me. I need to simulate the circuit before proceeding for PCB.

The aim is to have this cranking motor or such output waveforms at the Myrio GUI , to see the behavior of this Circuit.

I hope i made it clear, I am not sure. I feel firstly the design of circuit is crucial

 

Does the ECU need to run in reverse ?

 

Ya

ECU will be tested later for the cranking scenario, At first need to check with load of upto 5amps and 12V at load resistor (in place of a ecu first) .

 

The idea is some thing similar to the image in the attachments. H bridge driver IC with H bridge
