23-level cascaded H-bridge inverter + IPMSM EV drive

A multilevel inverter feeding an interior PM motor, run over a full driving cycle.

Switching model top level — Switching model, top level

Drive-cycle speed and power results — Drive-cycle results

Phase-shifted carriers — Phase-shifted PWM carriers

Aim

Drive an IPMSM with FOC and MTPA from a 23-level cascaded H-bridge inverter, and evaluate it over a standard drive cycle with average and switching models.

What you’ll learn

Field-oriented control with maximum torque per ampere (MTPA)
Phase-shifted carrier PWM and cell voltage balance
Average vs switching models for long simulations
Drive-cycle energy and range estimation
