pwde underated/kapos ang output mo..
o hindi kaya unstable talaga ang outputs mo sis...

dapat kasi sis. malaki ang trafo para mas mataas ang power output handling niya... anong klaseng inverter ba yan?.. pwde mo mapost para makilatis natin... baka hindi stable din ang driver/pwm niya.

Ganun ba un sir? Un kc circuit 1amp lng transfo. Pero pwd pla gmitan ng mas mlaki. Gumagamit lng i2 ng 2 mj2955 taz 2 68 ohm resistor. Ang B+ nya pasok sa pareh0ng emmiter ng transistor. Taz tg isa ng resistor sa base na c0nek sa c0lektor nun isang transistor. Salitan lng cla. Neg negativ nman un O sa 12v O 12v. Bwat 12v konek na sa colector nun tg 1 na transistor.

eto ba yun?


naka push pull configuration siya.. hndi rin siya stable. stressful ang pagpapalit niya...wala din siyang EMF stabilizer. na diode na naka shunt s coils ng 12V.. wala din siyang 2 Ecaps as charging & discharging..
mas maganda pa ang LM555 dyan.. mas recommend ko ito sayo lalot kong para lang sa cfl
12V Simple CFL Driver

dapat kasi sis.. ganito yan... 



disregard muna ang tranny ginamit... caps will be the pusher/pumper. Diodes nmn ang emf stabilizer.
problema lng dyan ay matakaw yan sa caps... masasabugan ka ^_^

try mo yung 555 ang driver. wala ka pang poproblemahin sa biasing
