Resonant Circuit Generates a High-Frequency Magnetic Field (.PDF Download)

    Aug. 20, 2015

    Generating a high-frequency magnetic field can be quite a challenge due to an assortment of technical issues. At high frequency, magnetic-coil impedance is large. It requires a high-voltage and high-frequency generator to produce enough current through the magnetic coil. However, it’s difficult to generate high frequency and high current at the same time using conventional amplifiers and drivers. Classic series resonant techniques have been used for high-frequency magnetic-field generation.1 The resonant circuit proposed in this article will further boost coil current by 2X...
