Product Description
The n is called the voltage ratio (the ratio of the n<1), the N1>N2, the V1>V2, the transformer is the buck transformer, the other is the boost transformer.
Efficiency of B. transformer:
At the rated power, the transformer's output power and the ratio of the input power, called the transformer's efficiency, is
ETA = x100%
In 7 / as the efficiency of the transformer; P1 power input, P2 output power.
When the transformer output power of P2 is equal to the input power P1 and efficiency ETA equal to 100%, transformer, will not generate any loss. But in fact, the transformer is not. When the total transmission power transformer to generate losses, such losses mainly copper loss and iron loss.
Copper loss refers to the loss caused by the transformer coil resistance. When the current through the coil resistance heating, the part of the electrical can is changed into heat and wear and tear. As the general coil wound by copper wire with insulation, therefore it is called for the copper loss.
