Single Phase Half Bridge and Full Bridge Inverter using MATLAB Alternating Current (AC) power supply is used for almost all the residential, commercial and industrial needs. But the biggest issue with AC is that it cannot be stored for future use. So AC is converted into DC and then DC is stored in batteries and ultra-capacitors. And now whenever AC is needed, DC is again converted into AC to run the AC based… |

Lead Acid Battery: Working, Construction and Charging/Discharging Almost every portable and handheld device consists of a battery. The battery is a storage device where energy is stored to provide power whenever needed. There are different types of batteries available in this modern electronics world, among them Lead Acid battery is commonly used for high power supply. Usually Lead Acid batteries are bigger in size with hard and heavy… |

How to make an Electromagnetic Coil Gun Coil Gun, as many people think (including me) is not just a fun toy with a tube and few coils around it which can shoot projectiles to a certain distance. Scientists at Sandia National Laboratories believe that a coilgun can be engineered to accelerate particles at a greater speed that is high enough to escape earth’s gravity. Yes, you heard that right! Coil gun could… |
