Abstract
A new single-phase II-type 5-level inverter for robot motor drive is presented in this paper. The topology with a reverse coupled inductor applies only four active power switches to achieve 5-level output, which is suitable for multilevel power inversion. Compared with traditional inverters used in motor servo drive system, the power loss and cost of the output filter inductor are reduced, and the conversion efficiency is enhanced, and the basic multi-level inverter topology are improved. The operation scenario with sinusoidal pulse width modulation (SPWM) is described in details. A simulation model and a prototype were built to verify the multilevel output under the SPWM modulation strategy.
