TRANSFORMER AND INDUCTOR COMPLEX WITH SERIES CONNECTION OF THE CAPACITOR IN A LOAD CIRCUIT
179 KB
A description of main elements of induction devices are given. We provided a consideration of comparative characteristics of inductor and capacitor module with different methods of reactive power compensation. Advantages and disadvantages of each method of compensation are given. We offered use of high-frequency matching transformers with cores made of amorphous or nanocrystalline alloys for extension of application of a series resonance (voltage resonance) in power supplies for induction devices. These new matching transformers have much lower magnetic losses, compared with previously applied matching transformers. Modeling of the offered schemes of power supplies with IGBT transistors in Matlab software package is made. We got results of modeling in the form of oscillograms of currents and voltages of high-frequency matching transformer, confirming an operability of offered schemes of power supplies for induction devices with series compensation and new matching transformers.
