Abstract
Possibility of hybridization of switching strategies for modulated inverters of six-phase multi-inverter drive has been shown in this paper. Hybrid switching schemes can be used for control of power system with unequal voltages of dc-links. In this case the proposed combined PWM techniques of inverters insure equal magnitude of the fundamental harmonics of the phase voltages for different ratios between dc-voltages of system. Combination of hybrid switching scheme with algorithms of synchronous PWM (for control of separate inverters) assures waveform symmetries of the phase voltages, and this fact has been confirmed by simulations.
