Hi,
I am working on building up database for remote controller for Air Conditioners.
I used Chris Young's IRLib to record and transmit various codes of LG and Dawlance air conditioner using Arduino Mega 2560.
While decoding codes of Dawlance Air conditioner I found out that the codes at temp...
the battery is 12 v 45Ah and i m going to charge at 5 amp which is 10% charging current,also i think buck converter will work when input is 16V so charge voltage maybe 14V and current should be 4~5 amp which is most suitable. if input varies below 12V then boost wil come in place which will...
Greetings,
I need to design buck/boost or CUK converter to charge a battery.
Input= 16V 7Amp
Output= 11~14V 5 Amp
I need to know if their are any IC's AVAILABLE which can control the output via pwm.
I searched some of them but found it to be difficult
Parasitic resistance is a tough thing to find out, but then it leads me to try different types of inductor maybe iron core,for now i was using ferrit core....
Also it leads to try using MOSFET rather than npn transistor with base connected to 200Ohm resistance fed by PWM from MicroController
well i tested the ckt physically and tend to get 7v at output without output cap but it couldnt drive any load may it be a 6v motor, no current was passing....
my source was a dc supply of 12v 1.2amp....
also whenever output cap was inserted the voltage drop to 1v....can u tell what could be...
By choke means this
https://en.wikipedia.org/wiki/Choke_(electronics)
Also is their any formula for calculating input cap ?
And shall the diode not be placed in opposite direction?
thebuck/boost ckt i made

Well,experimenting is the only solution to get the best design working. However, what i have read over the internet and in some books CUK is best when u need...
Greetings,
I have solar panel which produces following
Vmp=16V
Imp=7.5A
P=120W
Battery to be charged is 12V 45Ah Lead Acid
Now, I will be charging the battery at 14V and 5Amp (i.e., approx 10% of 45Amp)
I have found buck converter would be feasible for this solution but on the other hand if
PV...
could you please tell, if the signal source provides upto 25mAmp max,would that be enough? or can link to some formulation for the calculation.
For learning purpose
okay thanks for the suggestions, ill check the ckt practically and post the result.
Also answer post #10
for boost strap capacitor c3 and c4, only c4 100nf ceramic cap can be connected?
