Diode Commutation Results

Coil D

The graph of fig1 shows the difference in the commutating current decay for 1 diode and 10 diodes.

Fig1. Difference in commutating current decay.

Again the decay time for 10 diodes is almost one third that of 1 diode.

Table 1 shows the gain in velocity and energy using 10 diodes instead of 1.

Projectile Speed (m/s) 1 Diode Speed (m/s) 10 Diodes Gain (%) Energy (J) 1 Diode Energy (J) 10 Diodes Gain (%)
Solid 1.07E+1 1.25E+1 1.67E+1 7.25E-1 9.87E-1 3.62E+1
4mm Core 1.10E+1 1.28E+1 1.68E+1 6.58E-1 8.88E-1 3.63E+1
6mm Core 1.12E+1 1.31E+1 1.64E+1 5.28E-1 7.12E-1 3.56E+1

Table 1. Gains in speed and energy using multiple series diodes.

 

Now in this case we can see that the energy gains are similar to those for coil C with the cored projectiles showing slightly better gains.
