Four times pressure fluorescent lamp starting circuit diagram
When the A end is positive, B end is negative, the current path is A → L → C2 → D4 → B to make C2 be charged to the peak of electric supply. When the B end is positive, A end is negative, the current path is B → D3 → C1 → L → A to make C1 be charged to the peak of electric supply. At the same time, when A is positive, B is negative, electric supply connected to the voltage on C1 in series will pass D5 to make C3 charge to twice of the peak value; when B is positive, A is negative, electric supply connected to the voltage on C2 in series will pass D6 to make C4 charge to twice of the peak value.
