Hi, Me again.
I have been tasked to replace a step up power transformer in a machine.
But i just can't get the answers i need after much thinking.
In a simplistic RC circuit, there are 4 items
DC Power source (Normally voltage driven)
Switch (On/Off the circuit)
Resistor
Capacitor
All are in series right?
In my simplified circuit.
1) Step up transformer (Pri230V:Sec2000V, 16A:1.84A, Single Phase, 50Hz)
2) Full Bridge Rectifer
3) Charging Resistor, 33 ohms
4) Capacitor Bank, 2000Vdc@ 2000uF, total energy rated 4000J
An SCR will turn on power to the transformer which in turn transfers power to the capacitors for charging till 2000Vdc.
My doubt is, this setup is able to charge the capacitor up at 600J/sec as stated by the manufacturer. The specifications are quite accurate. Normally it finishes before 6 seconds on my stopwatch.
I tried the few calculations but it didn't work out,
1) 2000V source with 33 ohms, RC constant does not work out right.
2) Using a source of 1.84A with 33 ohms, it does not work out right either.
Is my direction correct?
