maan lo maine buck convertor me ye banaya (BUCK CONVertor)
5V input rakha...
1A current limit kya...
ab...
1. jab 1ohm ka load lagaya... to 1A flow hogi, mean voltage across load = 1V
2. jab 3ohm ka load lagaya... to 1A flow hogi, mean voltage across load = 3V
3. jab 10ohm ka load lagaya... to 1A flow hogi, mean voltage across load = 10V
4. jab 25ohm ka load lagaya... to 1A flow hogi, mean voltage across load = 25V
Above me se kaun se points correct hai...
Agar all of them... to buck convertor 5v se 25V bhi bana sakta hai kya???(is modification se...)
5v input me output kabhi bhi 5 se upar nhi hogi. To 5ohm ke niche hoga to constant current dega, warna constant voltage
@@FreeCircuitLab ok
With only this modification,
0.5ohm resistance के साथ क्या, voltage 0.5V होगा???
(as unmodified buck converter has a lower limit about 1.2V...)
Similarly, a modified boost convertor, can it by pass its 40v upper limit?
Mind blowing 👍
Sir please add kariye short circuit protection feature is lm2596 module me I am your big supporting guy 😎
for a buck convertor modified in this way, with 5V Input,

3. jab 10ohm ka load lagaya... to 1A flow hogi, mean voltage across load = 10V
