Abstract
High-power medium-voltage frequency-controlled electric drives are based on multilevel inverters of different layout. The paper is dedicated to enhancing characteristics of the frequency converter by means of a four-level voltage inverter with floating capacitors. The formation process of a four-level voltage inverter is studied on the basis of a computer model simulated with application of the Matlab Simulink software. An algorithmic method of voltage regulation with floating capacitors is offered and tested.
