A new strategy for direct torque control with im-posed
switching frequency (DiCoIF) is proposed. This strategy was
specially designed to operate with a multicell (flying capacitors)
inverter with any number of levels, which means it can also be
used for standard two-level inverters. This approach combines the
well known advantages of the multicell inverter with those of a di-rect
torque controlled (DTC) based strategy. It is shown that the
multicell topology presents enough degrees of freedom to control
both torque and flux with very low ripple and high dynamics on
one hand, and to impose the switching frequency and the capaci-tors
voltage balance on the other hand. Experimental and simula-tion
results, obtained with a standard two-level inverter and with a
four-level multicell inverter, are presented and discussed. Finally,
a comparative analysis either with the classical DTC and field ori-ented
techniques is carried out.
