Linear and non-linear voltage-to-frequency multi-zone control of synchronously modulated power electronic inverters

Abstract

The publication presents a brief analysis of the results of a study of power electronic converters of pa-rameters of electrical energy based on voltage source in-verters (VSIs) and neutral-point-clamped inverters (NPCIs) with scalar control modes realizable by algorithms of syn-chronous multi-zone pulsewidth modulation (SMZ PWM) that can provide both linear and required nonlinear depe-ndences between the output voltage and fundamental frequency of inverters (Voltage/Frequency (V/F)). Simulati-on results showed a behavior of variable speed drives based on inverters regulated in accordance with schemes of SMZ PWM.
