Shaft Voltage Suppression of Double-fed Generator for High Power Wind Turbine
Kongzhi Yu Xinxi Jishu, 2013 The mechanism and adverse effects of shaft voltage in double-fed generator generated by inverter is analyzed. As shaft voltage is part of common-mode voltage, a new LCL-filter of converter for suppression of common-mode voltage is proposed through ...

Common-Mode Voltage-Reduction Method of 7-Phase BLDC Motor Control System
Energies, 2023 This paper describes a method for reducing the common-mode voltage in a seven-phase brushless DC motor (BLDC) drive. The conventional interleaved method used in the three-phase inverter system is extended and applied. The proposed phase-phase interleaved

Common-Mode Voltage Reduction of Three-Level Four-Leg PWM Converter [PDF]
IEEE Transactions on Industry Applications, 2014 This paper presents a carrier-based pulsewidth modulation (PWM) method that reduces the common-mode voltage (CMV) of a three-level four-leg converter. Based on an analysis of space vector PWM (SVPWM) and sinusoidal-PWM switching patterns, the fourth-leg pole voltage of a three-phase converter, known as the “f pole voltage,” is manipulated to reduce the

Differential Bloch Oscillating Transistor Pair
, 2013 We examine a Bloch Oscillating Transistor pair as a differential stage for cryogenic low-noise measurements. Using two oppositely biased, nearly symmetric Bloch Oscillating Transistors, we measured the sum and difference signals in the current gain and ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild
