The permanent magnet synchronous motor (PMSM) avoids commutation-related torque ripples and produces smooth torque.Its great handling capacity and better efficiency make it an excellent choice for high-demand applications.A typical PM motor drive fed with pulse width-modulated voltages may cause the motor insulation to break down if rapid voltages (dv/dt) occur across the motor terminals.Applying variable voltage with low dv/dt and implementing multiple inverter topology can solve 2 Person Backpack this issue.Multilevel converters have minimal switching losses, better power quality and the ability to operate at both fundamental and higher switching frequencies.

In this study, a three phase stacked multilevel inverter-based FOC driven PMSM drive design is proposed.Here, the neutral point is a capacitor intermediate point on DC side, where current is naturally balanced throughout a switching cycle.This makes it possible to use downstream batteries and even lower voltage equipment, greatly increasing efficiency, improved performance and smother control at low speed.Therefore, direct-battery-driven electric vehicles will be able to use this.A 33 level inverter-based PMSM drive was used to implement the FOC, and the simulation results were used to validate it.

The Matlab/Simulink tool is used to simulate the Luggage entire system.
