110 volt to 220 volt converter how to#

If it is ordinary voltage converter silicon steel sheet, dry-type voltage converter, can take 15-16.5 kilogauss (First calculated with 16). Know the core cross-sectional area, each turn of the voltage et=BXS/450, et is the voltage for each turn, B is the magnetic density.

Finally, see whether your core window can put down the coil. Basically the other parameters of the voltage converter can be determined after the calculation. Silicon steel sheet is the voltage converter core cross-sectional area. Known core area is 3.5X3.2cm^2, the primary voltage 110V and secondary voltage 220V, seeking: Second turn and diameter, current. Seeking the current must be calculated using the electric power relationship, when there are a number of categories. P1=P2+P3 and U1/N1=U2/N2=U3/N3 when there are two secondary coils. Note that the above equation is valid only when the ideal voltage converter has only one secondary coil. In addition, the current ratio I1/I2=N2/N1 and electric power P1=P2. When n>1, then N1N1, The induced electromotive force is even higher than the voltage applied to primary. An alternating voltage is applied to the primary winding to induce electromotive force at both ends of the secondary coil. The input voltage must be alternating current source whose output voltage is proportional to the turns’ ratio of the output input coil.įormula and description: The number of turns in the two sets of voltage converter respectively is N1 and N2, N1 is the primary and N2 is secondary. When the primary coil through the AC current, the iron core (or magnetic core) will produce AC magnetic flux, the secondary coil induces a voltage (or current).

Step-up voltage converter working principle: Step-up voltage converter is to transform low AC voltage, high current, low impedance to high AC voltage, low current and high impedance devices. The primary current of the voltage converter is the power/220V the secondary current is the power/secondary voltage. Turns ratio: Primary voltage/secondary voltageX1.05, which is 220V/secondary voltageX1.05.ĭetermination of the number of primary circles: 40 to 50 divided by the core cross-sectional area (empirical formula), depending on the quality of the core is good or poor, good core can take 40, poorer core can take 50.Ĭore cross-sectional area: S=1.2X√(Power/Efficiency)Ĭopper cross-sectional area: according to the current calculation, the general take 2.5A per square millimeter. Secondary coil wire diameter d2=0.8√I2=0.8√2=1.14mmĪssume that the input of the power converter is connected to 220 volts. Input capacity=voltage converter output capacity/0.8=275VA Voltage converter output capacity=110X2=220VA Simple calculation of voltage converters:įor example, your core section=3.5X1.6=5.6cm^2, so the number of turns per volt=55/5.6=9.8turnsġ.05 in the calculation of the secondary coil turns is to the pressure drop considering load.Īssume the output voltage is 110V and the output current is 2A.
