Analysis of electromagnetic processes in the three phase multizone current source inverter

In this paper detailed analysis of the electromagnetic processes in the new multizone current source inverter was carried out, resulting in the analytical ratios for the qualitative evaluation of the load currents, depending on the relative resistance of the load, as well as an external characteristics of converter by using the method of differential equations algebraization was obtained [1].
