Hi
[In context of determining Maximum Power Point Tracking (MPPT) for charging 12 V, 3 Ah battery using 24 V solar panels]
I m designing a buck converter to track Maximum power point of PV panel for charging 12 V battery.
I need to know what is the relationship between output current &...
Hi
I wish to design a buck converter for charging 12 V and 7 Ah Lead Acid battery from PV panels.
My panels are:
21.1 V: Open Circuit Voltage (Input to buck converter)
4.12 A: Short Circuit Current (Input to buck converter)
I need buck converter of output 4 A, 15 V = 60 W
I am using IRF 540...
What is input impedance of ADC?
What and how does input impedance of ADC effect my reading?
If voltage divider method is not reliable should I opt op-amp method?
I m sorry for my stupid questions. My electronics is not very good.
Pl assist
Okay.
Another question: Which method is better to read voltage. Via voltage divider circuit or attenuating voltage gain via amplifier?
Appreciate your kind assistance
Ohms law. 12/100 k = 120 uA
My application is Battery Charging through Solar Panels. So naturally current depends on rating of solar panel and other daylight conditions. I need to read voltage from Solar Panel as well.
If its a 40 Watt panel with 12 V output, it could give up to 3 A current...
Hi
I wish to read a 12 V battery voltage on Arduino Mega 2560 ADC pin. To do that, there are two methods.
1. Use a voltage divider circuit.
2. Use an op-amp that would attenuate the voltage to keep it as low as 5 V like in given figure I m reading 14 V of battery by scaling it down to 4.19...
