I post it because i want to know if anyone of you see any rare in this circuit made in proteus 8.6, i accept any observation, this circuit provide 12v of output and 3 modes of charging fast(15 A), medium(10 A) and slow(5 A), every part of the circuit are made of the components with the right specification for the support of high current but i think they are gonna lose current in the transistors because the heat, do everybody think this will work with the right heat dissipator?.!circuit for the charger made in proteus]1

    \$\begingroup\$ If dV=10ms*Ic/C = 10ms*15A/4.7mF=30V , you can see the Cap mF is about 10% of what it needs to be in this design. And the two regulators have ~4V drop total, Go buy one until you learn how to make one. \$\endgroup\$ – Sunnyskyguy EE75 Apr 25 at 16:05
