Introduction

Noraisyah Binti Mohamed Shah 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, his work has garnered attention for its innovative approaches and practical applications.

Latest Patents

Noraisyah's latest patents include a "Method of operating a multi-level switched capacitor boost inverter." This invention features a series connection of a two-switched capacitor circuit, a source module, and at least one one-switched capacitor circuit. The design utilizes level-shifted pulse width modulation to apply gate pulses to the switches. Remarkably, this multi-level switched capacitor boost inverter operates with only three capacitors and a single DC voltage source, generating thirteen voltage levels at load terminals with a voltage gain of three. The capacitors in the two-switched capacitor circuit are 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 the "Method for generating output voltages with a boost inverter." This invention describes 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 previous invention, the capacitors of the 11-level boost active neutral point clamped inverter are also self-balancing.
