Abstract: High-power converters and/or high-speed motor drives often operate at low-carrier ratios, particularly at higher fundamental frequencies (and consequential higher modulation indices), ...
Modulation advances have fueled more efficient use of bandwidth, although conventional modulation formats still require allowance for upper and lower sidebands around the carrier frequency. Ultra ...

Abstract: Due to the requirement of low cost in photovoltaic (PV) applications, an eight-switch three-phase three-level inverter (TP-TLI) and its modulation strategy have been proposed. However, it ...
Space vector modulation (SVM) is a sophisticated digital control technique that improves three-phase inverter performance over traditional sinusoidal PWM (SPWM). SVM’s higher DC bus utilization ...
The 32-year-old has missed South Africa’s last four matches, including the 3-0 victory over Rwanda in Mbombela that secured qualification for next year’s FIFA World Cup in the Americas. Kekana remains ...
In addition to a redesigned front panel and user interface, the R&S SMW200A now has modified microwave hardware for greater EVM performance. It also boasts higher output power in the frequency range ...
Recently, a research team led by Prof. LI Chuanfeng from the University of Science and Technology of China (USTC) achieved a breakthrough in quantum photonics. They developed an on-chip photonic ...
Where digital and analog designs are overlapping, and why it’s becoming more difficult to ensure they work as expected over their lifetimes. Pujol: We need some abstraction because we cannot ...
