Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...
Abstract: In the field of modern mobile communication, (Quadrature Phase Shift Keying) QPSK modulation technology is widely used, which has a great advantage that it can work normally in a limited ...
Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Complex modulation of optical fields (i.e., the control of light’s amplitude and phase) is vital to the ...

Overmodulation techniques are used to improve dc bus voltage utilization for three-phase voltage-source converters (VSCs), resulting in significant reduction in fundamental voltage gain. Conventional ...
Abstract: M-ary quadrature amplitude modulation (MQAM) is a technique that modulates amplitude and phase simultaneously. In MQAM systems, amplitude and phase are modulated independently, mitigating ...
Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters. The ...
Advanced sleep phase disorder is a rare condition that causes your natural circadian rhythm, or sleep-wake cycle, to occur earlier than typical. As humans, our sleep-wake cycle— also known as our ...
