I am having a battery balancing requirement for 18 batteries. My total output voltage of batteries is 192V to 260V. I am planning to use 7Ah batteries.
1. I am planning to use maximum 7Ah batteries.2. Can I get some lower-cost MOSFETs since current will be less.3. I need to use 5 auxiliary batteries which will increase the cost. So which supercapacitor or high voltage capacitor can be used.
The circuit in the posting will not work because AUXN is connected to the battery stack. Powering the circuit will cause parts to fail.
I didn't understand your reply. I have done some corrections. Here I changed auxiliary battery numbers. I have just connected the application note diagrams for my requirement. I have used only 5 to reduce the cost. For 6 LT3305, I have done the interleaving diagram.
See attachment. Connections highlighted in red may not be made. AUXN must not be connected to battery stack.
Ok. Now I understood. By mistake I have drawn line in paint. I will correct it and send you again. Please verify.
Thank you sir.
I have updated the file and attached here.
