The frequency signal through power electronic circuits into a high-frequency signal

Power transformer is mainly used in power electronics technology, the basic principle is the power frequency signal through power electronic circuits into a high-frequency signal, ie upscaling and high frequency isolation transformer coupling  electri cenergy meter , and then restore the frequency signal, the reduced frequency. By using appropriate control programs to control the operation of the device power  air circuit breaker , which will one frequency, voltage, power conversion waveform to another frequency, voltage, power waveform. The volume of the intermediate isolation transformer core material depends on the saturation magnetic flux density and the winding core and the maximum allowable temperature rise.
