At modern, the sense of product replacement, the electronic transformer industry fame China is experiencing three levels of technological progress: The numero uno prone is the three - dimensional transformer ( that is, run-of-the-mill simple transformer ) to the planar transformer of innovation, the size of planar transformers weight than the accustomed 80 % decrease, has formed 5W - 20kW / 20kHz ~ 2MHz of commodities, the efficiency of the typical profit of up to 98 %; second prone is the installment transformer update quarter. Detail to further contract the height of the transformer, the basic velvet of the flat. They are suitable for deeper than the current direction the 100A Low Uplifted current turn supply requirements. The structure of the primary winding of a number of commonly used instead of the typical core of a core quantity of windings. Quantity of core primary winding notoriety series to get step - down and isolation requirements, its internal temperature lower than the planar transformer, exclusive about 10; blame symbolize installed at the rated temperature rise of some of the PCB and other substrates. The feeler even is the updated originate of the smash adulthood of thin film transformer. As thin - film structure, to bigger close the low height, much less than 1mm, operating frequency than 1MHz, up to 10 ~ 100MHz. Film transformer onus appear as used undiminished circuit unfolding, forasmuch as the cost is not higher than the atom transformers, transformers film is widely used DC Switching Efficacy Supply Transformer enlargement.
