My small refrigerator is Haier, you can run under 220v 5 hours, but can not be used for a long time, how can the refrigerator at home to play a role? Need DC 12v, power in the 38-48w. What kind of transformer does a DC power cord need to use? Or how to do? consult!
Can go to the electronic components shopping malls (market) to buy a 220V / 12V, 50 watts of power transformers, and a 4 amp rectifier bridge pile, plus two 10000 microfarad, 50V capacitor can be used as a 12V, 4A that is 50 watts of DC power, and all costs about 15-20 yuan.
Do not understand the small refrigerator circuit, can only say something about. The car is only 12V DC battery, so with 12V power supply, do not know the compressor is a direct DC work, or with the inverter will be 12V DC into 220V AC power use. If it is to use the inverter, then just to find the compressor power wiring, directly with the AC on the line. If 12V DC work, it would use a 100W or so transformer, primary 220V, secondary 14V, the production of a 12V, 5A or more current rectifier circuit.
Need to use power converter;
