Why not put a resistive load to ground as well as the battery to collect charges ?//The resistor will act as load to the inductor for switching current stability ..
The battery +ve needs be provided with a diode for forward current into the plates and prevent VDC to be present to the MOSFET drain.when MOSFET is OFF.
Hi, the video shows a resistive load, the circuit is only working with a resistive load. I would like to make the circuit work as a 12 volt battery charger. When I use a 12 volt battery for the load the mosfet does not turn on.
The bootstrap capacitor of the IR2117 is charged to 10 volts. Vs of the mosfet and the IR2117 are connected to plus 12 volts of the battery. The maximum voltage of the bootstrap capacitor can be +/- 20 volts, is that referenced to, ground or to Vs?? I do not know.
When I use a 12 battery as a load, what does the bootstrap capacitor have to be charged to and what do I use as reference? Thank you for any help received.
How about your project sir?
I am developing similar circuit as yours. My buck circuit is able to work at resistive load and to charge battery 12V. However, I am facing issues like noises, voltage spike which damage microcontroller and mosfet driver.
May you have any suggestion. It will be appreciated.
Thank you
Hi, can you post your circuit schematic?
