Abstract (English): A number of modulation strategies are used in multi-level power conversion applications. This paper is focused on novel multi-carrier PWM methods which have been extended for the use in cascaded H-bridge multi-level inverters. The new multi-carrier PWM method can be optimized or balanced by the use of switching in the cascaded H-bridge multi-level inverter. A five-level cascaded H-bridge multi-level inverter has been simulated and controlled with the novel multi-carrier PWM proposed in this paper for operation as a voltage-source inverter (VSI). In compliance with the multi-carrier PWM method, the switching frequency can be lower than or higher than the carrier frequency, being a function of the displacement phase angle between the carrier set and the reference waveform. By adjusting the displacement phase angle in the multi-carrier PWM control strategy the switching losses can be minimized to make a cascaded multilevel inverter more efficient. In the traditional multi-carrier PWM technique, the top and bottom switches are switched much more often than it is done in the intermediate devices. A novel method of balancing the device switchings for all the levels in a cascaded H-bridge inverter has been demonstrated for multi-carrier PWM by varying the frequency for different triangle wave carrier bands.

Abstract (Latvian): Daudzpakāpju jaudas pārveidošanai tiek izmantotas vairākas modulēšanas stratēǵijas. Šis raksts ir vērsts uz jaunu multifrekvenču PWM metodēm, kuras tika paplašinātas izmantošanai kaskādes H-tilta daudzpakāpju inverterā. Jaunā multifrekvenču PWM metode var tikt optimizēta vai sabalansēta ar ieslēgšanas darbību kaskādes H-tilta daudzpakāpju inverterā. Piecpakāpju kaskādes H-tilta daudzpakāpju inverteram tika veikta simulācija, un tas tika kontrolēts ar jauno multifrekvenču PWM, kurš raksta izpratnē kalpo par sprieguma avota inverteru (VSI). Multifrekvenču PWM metodē ieslēgšanas frekvence var būt mazāka vai lielāka par nesējfrekvenci un ir funkcija no atrašanās fāzes leņķa starp nesēju un attiecīgo ciklu. Atrašanās fāzes leņķa ieregulēšana multifrekvenču PWM kontroles stratēǵijā ļauj samazināt ieslēgšanas zudumus kaskādes daudzpakāpju inverterā. Tradicionālajā multifrekvenču PWM tehnoloǵijā augšējais un apakšējais slēdzis tiek ieslēgts biežāk nekā vidusmēra iekārtās. Jauna metode, kas ļauj sabalansēt iekārtas ieslēgšanas darbības visu pakāpju kaskādes H-tilta inverteros, tika demonstrēta multifrekvenču PWM, mainot frekvences dažādām trijstūra viļņu frekvenču joslām. Piecpakāpju kaskādes H-tilta daudzpakāpju invertera darbība tika simulēta un pārbaudīta ar jaunu multifrekvenču PWM. Šajā rakstā piedāvātā jaunā multifrekvenču PWM metode var tikt optimizēta vai sabalansēta ar ieslēgšanas darbību kaskādes H-tilta daudzpakāpju inverterā. [ABSTRACT FROM AUTHOR]
