Hardware implementation of cascaded H-bridge inverters

, 2016
Medium Voltage (MV) converters have lately been quite popular for high power motor drives. Variable speed control of the motor and the drop in the energy loss i.e. increase in efficiency of the system are the main advantages of these drives. These MV converters are widely used in industries for fans, driving pumps, and marine propulsion system of ships.

Enhancing Stability of Few‐Layer Black Phosphorus (FLBP) Through Nitrocellulose Coating: A Robust Defense Mechanism Against Degradation

Advanced Materials Interfaces, EarlyView.
In this research, a simple and scalable strategy for protection of a few‐layer black phosphorus (FLBP) with a cellulose nitrate‐based material is presented. The FLBP is structurally and morphologically characterized. The FLBP stability with and without nitrocellulose protection is monitored by interferometric method, surface profile examination, and ...
