Title: Innovations by Saad Mekhilef
Introduction
Saad Mekhilef is a prominent inventor based in Jeddah, Saudi Arabia. He has made significant contributions to the field of electrical engineering, particularly in the development of advanced inverter technologies. With a total of six patents to his name, Mekhilef continues to push the boundaries of innovation in his field.
Latest Patents
One of Mekhilef's latest patents is a method of operating a multi-level switched capacitor boost inverter. This innovative device includes a series connection of a two-switched capacitor circuit, a source module, and at least one one-switched capacitor circuit. The inverter utilizes level-shifted pulse width modulation to apply gate pulses to the switches. Remarkably, it uses only three capacitors and a single DC voltage source to generate thirteen voltage levels at load terminals, achieving a voltage gain of three. The capacitors in the two-switched capacitor circuit are designed to be self-balancing, and additional one-switched capacitor circuits can be added in series to increase the number of levels and gain.
Another notable patent is a method for generating output voltages with a boost inverter. This invention features an 11 level boost active neutral point clamped (BANPC) inverter that employs four capacitors and a single DC voltage source to produce eleven voltage levels at load terminals, with a voltage gain of 2.5. The design minimizes the number of switching elements used, and gate pulses for the switches are generated using nearest level control pulse width modulation (NLC-PWM). Similar to his other invention, the capacitors in this inverter are also self-balancing.
