Power Inverter

Post by alvinquimbo on Thu May 01, 2014 8:22 pm

Mga master, tanong ko lang? gagawa sana ako ng power inverter kaso lang kakayanin po ba nya ang isang electric fan, kasi mostly ng mga appliances is sinusouidal wave ang waveform pag inverter po ay square wave.Di po ba nya sisirain ang motor nito. Kasi uso ang brownout,tapos mainit.para lang po sa ank ko kasi madaling magpawis.ang load lang talaga ng inverter is electric fan po.Salamat po for any reply and comments.

hindi issues ang waveform sa problema mo alvin. dahil inductive load ang electric fan. di gaya ng mga electronic appliances. ang pinaka malaking problema mo dyan ay kakayanin ba ng inverter mo ang load mo? at ilang time lang ang kakayanin ng baterya?

pag mataas ang load mas mabilis huhugot ng kuryente. ang alam ko nasa 60W ang mga electric fan. subukan natin i compute. halimbawa. gagamit kayo ng full charge na 12V 12AH battery aprox. 144Wh. at ang load o electric fan mo ay 60W. 144/60 = 2.4 x 60% efficiency = 1.44 hours. pag maliit ang load mo mas mataas ang oras na paggagamitan. o di kaya kong mas malaki ang baterya gaya ng nasa mga jeep ay mas mainam. kong gagawa pa kayo ng inverter, meron din binibintang mga inverter ang cdr-king. modified sine wave na rin daw.

Musta mga master,cnxa na ngaon lang nagreply busy po kasi sa planta shifting schedule kasi at 12hrs palagi ang work,kaya minsan nakakastress din..mayroon palang 12v efan,di nalang ako gagawa nito kung may efan na 12v.salamat sa information sir ultra at sir pyroelectro.
@sir hertz,salamat po sa explanation sir hertz basi sa power inverter..mas praktikal talaga kung bibili nalang ng readymade at least may pagpipilian ka sa market..tnx a lot,more power.

@alvin. yes mas praktikal ang bumili nalang. pero meron din namang advantages ang sariling gawa. you can learn from it. kaelangan nga lang mag invest o gumatos ng mga pyesa kong sakaling mag ta try and error. but in a long way. you will understand soon the principle of the circuit.

OT: @sir ultra. sir may nakapagsabi sakin na may Green tech Electronic na raw dyan sa davao. subukan mong bisitahin ang Manager nila. He's a close friend of mine.
