Despite numerous advantages of space vector pulse width modulation (SVPWM) methods, their implementation on multilevel inverters (MLI) is onerous. Due to the ever-increasing use of MLIs in power electronic applications, it is essential to implement efficient modulation procedures aiming to keep control sampling periods sufficiently short. Here, a novel and straightforward SVPWM Strategy is introduced, which uses algebraic functions throughout the procedure and avoids using hardware-consuming trigonometric functions. Look-up tables and region detection are no more necessary.
