<p>PURPOSE: A method and a device for current balancing, an LED lighting equipment, an LCD back/light module, and an LCD display equipment are provided to make the current flowing in a plurality of loads balance by using electromagnetic force which is generated from a coil. CONSTITUTION: A power supply unit(10) outputs an AC current. A plurality of serial circuits are connected to the output of the power supply unit. Each serial circuit comprises at least one coil(N1,S1) and a voltage multiplier rectifier which is comprised of rectifier elements(D1,D11,D2,D12) and capacitors(C1,C11,C2,C12). The load is connected to the output of the voltage multiplier rectifier. The current flowing in the load is balanced by the electromagnetic force generated from the coil.</p> |
