High Frequency Transformer Passes Low Frequency Electric Power Technology

Nov 08, 2016

Development of high frequency switching technology, withdrew from many fields of power frequency transformer, but in the need to isolate uninterruptible power supplies, digital linear power amplifier, output low frequency sine wave DC/AC converters and many other fields, in order to isolate or transform the voltage needed, have to keep the low frequency transformers. In order to overcome the disadvantages such as low frequency transformer heavy, bulky, with high frequency switching technology continues to mature, make it possible to remove low frequency transformers. Figure 1 shows a typical circuit structure.
