Implementation of a closed loop SHMPWM technique for three level converters [PDF]
High power converters are built using high-voltage and high-current rated semiconductors. The commutation of these devices imply large amounts of energy per cycle leading to very low switching frequency in order to avoid a high rise on the semiconductors

Runge–Kutta optimization‐based selective harmonic elimination in an H‐bridge multilevel inverter
The application of iterative techniques for solving the Selective Harmonic Elimination Pulse Width Modulation (SHE‐PWM) problem, such as the Newton–Raphson (NR) method, can tend to get stuck at local optima in the solution space.
