Sometimes what inspires us to work isn't necessarily for peace and prosperity. Ultratek Defense Systems Engineering has built a portable high powered, projectile launching, "Coilgun."
Long story short, it takes all the power stored in a 430V @ 3.29mF capacitor bank and puts it through a magnetic coil of wire, which then accelerates and propels a metal object placed inside it.
Based on the following:
-Power supply: 12V NiMH battery (fires about 15 times/charge)
- Charging: 40 watt regulated ZVS flyback driver (charge time ~30s)
- Capacitor bank: 4x 3900uF @ 400VDC
- Stored electrical energy: 1.248kJ
- Switching: one massive stud-mount SCR
- Clamping diode: NONE- charger output bridge rectifier takes care of this
- Barry's sim puts the discharge at a peak of 4.6kA with zero crossing at 2.68ms.
