Three Phase to Single Phase Conveter

[mAgtataHO]

good Day guys

details naman po on phase converter
or do have any simpple circuit about single phase-to three phase..

thanks

[RiDdLeR???]

3-phase to single phase conversion is very easy.  Just use one line instead of of three.  Single phase to three phase I have no idea.  Lets wait for the experts to butt in.  But I think almost impossible but still doable by introducing lags at the output from a single line output.

eto na yung simplest way na nakita ko. yung iba kasi requires a lot of Electronics na. yung mga Inverters para sa motor, pwedeng umandar sa Single Phase. converted muna kasi sa DC bus tapos PWM para maging 3 phase.

di mu naman kelangang iconvert pa yung 3phase to single phase ah. kung ang system voltage mo eh 230vac 3phase at gusto mo ng single phase na 230vac eh yung dalawang line lang ang gamitin mo. pero kung madae kang load na single phase tapos 3 phase ang supply mo eh kelngan mo lang gawin eh load balancing.

nasagot ko ba tanung mo?

hehehe ganon nga dalawang linya lang kailangan mo kung single phase lang kailangan mo, at kung kailangan mo naman na gamitin yung max power ng 3 phase mo simple lang yan tatlong transformer lang kailangan mo

naguluhan ako ah. yung thread kasi 3 to 1 pero yung question 1 to 3.

anu yung max power? para saan yung tatlong transformer?

1 plus 1 lang naman eh..

Kung dalawang line ang gagamitin mo na galing sa three phase 3 lines, di ba out of phase by 120  or 240 deg yung voltahe ng dalawang active line?  Please enlighten me further kasi wala ako alam sa power generation and distribution.

[1110000]

anu yung max power? para saan yung tatlong transformer?

kunwari 600W ang 3 phase mo ng kuryente, kung kukuhanin mo lang ang single phase noon ay 200W lang ang max power na pede mong makuha kung tatlong transformer coconvert mo yung 600W na 3 phase sa almost 600W na single phase
almost 600W lang kasi may looses ang transformer

[ahlburuto]

wala namang problema dun ah. 230vac pa din makuha mo na voltage dun at 60hz pa din.... ang mahalaga sa 3phase system eh yung load balancing. halimbawa, kung sa factory mo eh meron kang 3 load na single phase at ang wattage nya eh sabihin natin na 10,000watts, ang connection nun sa line eh yung load 1 sa L1 & L2 yung load 2 eh sa L2 & L3 at yung load 3 eh L1 & L3. para balanse yung current mo sa 3 phase.

ang ibig sabihin ko ay yung MAXIMUM WATTAGE LOAD kung 600W ang 3 phase mo 600W lang ang maximum na pwede mong i load ay 600W lang, at kung gagamitin mo lang eh yung 1 phase mahahati sa tatlo ang maximum yung 600W na 3 phase mo
kaya ang maximum mo na lang na pede i load eh 200W na lang
 kung gagamit ka naman ng tatlong transformer i kokonvert mo yung 600W na 3 phase sa 600W din na 1 phase (hindi step down transformer ito)

hindi naman para sayo ang reply ko eh. ke alyas

Hindi ko pa rin magets.  Mathematically, you'll definitely get either more or less than 230V output if you use two 230V out of phase lines.

Your answer just assumes you'll get 230V 60Hz single phase from using 2 230 live lines which are out of phase w/o any explanation.

Ang pagkaka-intindi ko, in order to get lets say a single phase 230V from a three-phase system is by tapping only one line lets say L1, and feeding it to a 1:1 transformer.  The output of the transformer is center-tapped and the center tap is earth grounded.  This way, you get 2 115V on each line that adds up to a 230V output. 

I'm not an electrical engineer so I'm not sure of my understanding.

ang alam ko ang 3 phase na ginagamit ng kapit bahay namin 380-400V kaya lung ididivide mo sa tatlo ay 126V-133V eh pag kumukuha ka ng 1 phase sa 3 phase dalawa ang kukunin mo kaya ang makukuha mo na voltage eh 252V-266V

[RiDdLeR???]

Ok, that explains the voltages .  Ang hindi ko pa rin magets is papaano magiging 60Hz single phase  ang line  kung yung source at dual phase.  May transformer or inductor ba na kinakabit para mag-lag yung isang line para maging in phase yung frequency nung  dalawang lines?
