  • Multi-level high-speed adjustable speed drive
    Patent number: 10727774
    Abstract: A multi-level high-speed adjustable speed drive has a plurality of modular multilevel, 3-phase inverter bridges, wherein the multilevel, 3-phase inverter bridges operate with fundamental frequency, f, wherein the multilevel, 3-phase inverter bridges include at least three levels, wherein the multilevel, 3-phase inverter bridges operate in Pulse-Width Modulation (PWM) mode with 9 to 21× or operating in Fundamental Frequency Mode (FFM), wherein inverter commutation frequency equals the fundamental frequency, wherein the multilevel, 3-phase inverters operate with split phase such that one group is displaced from the other by an angle, ?=60°/q, wherein the phase displacement of a harmonic component of order n between groups, ?n is n?/q; a high-speed polyphase motor with phases arranged in q 3-phase groups; and electromagnetic means for blocking selected groups of harmonics while passing components at fundamental frequency, f, wherein the electromagnetic means includes coils carrying motor current linked by a magn
