Latest Patents

One of his latest patents is a predictive control method for a multilevel converter. This innovation focuses on reducing computation time for model predictive control (MPC) of a five-level dual T-type drive. It considers the DC link capacitor balancing and common-mode voltage (CMV) along with torque control of an open-ends induction motor. The method determines a reduced set of switching states for the MPC, which can either reduce or eliminate CMV. The cost function minimization generates a voltage vector that produces gating signals for the converter switches. This reduced switching state MPC significantly enhances performance while minimizing computation time.

Another significant patent by Mamdouh is related to predictive torque control and capacitor balancing of a silicon-carbide based dual T-type drive system. This innovation involves capacitor balancing of a dual three-level T-type converter using silicon carbide (SiC) discrete semiconductors. The converter feeds an open-ends induction motor (OEIM). A model predictive control (MPC) utilizing a two-step cost function calculation was developed to balance the DC link capacitors while simultaneously controlling the machine torque. The number of redundant switching states was reduced without affecting the operating voltage vectors, leading to a substantial decrease in computational time. Simulation and experimental results have shown good agreement.
