the overall model:

power:

220VAC -> (power supply module)

24VDC -> (ZVS)

2KHz 48VAC -> (transformer)

300VDc -> capacitor

capacitor (there are 6 of these in total)

another pespective:

the fireworks pellet is covered by metal foil and would be acclerated 3 times,

our test result shows that the pellet can ve sent to around 20M high.
