How can I light a fluorescent lamp?

I want to design a circuit that lights a fluorescent lamp.

From my knowledge, I know that in order to light a fluorescent lamp, we must apply V1 voltage form from inputs A and C to B and D (A & C and B & D are short in this phase). After T seconds, we apply V2 voltage form from A and B to C and D (A & B and C & D are short this time).

Is my method right? If yes, can you propose a means to determine these V1, V2 and T unknowns? What are the typical values for these?

I can only guess V2 as
V2(t) ≈ 311*cos(wt) (V), where w = 2*pi*50 rad/s
for a 220V fluorescent lamp.

this will get you started

To glow a fluorescent lamp you have to apply around 1kv b/w two ends .ie any one terminal from both side
once ionization starts voltage can be reduced to around 110.

What do you mean by "b/w", is that a unit?

I assume b/w means between (or across)

Thus 1000 V, or 1 kV across the bulb to start it, then reduce the voltage.

yes i mean across,
here you can find a circuit which will do it from 230ac
