Several pulsewidth modulation (PWM) strategies have been proposed for three-phase multilevel converters. Typically, these PWM methods can be either space-vector or carrier-based implemented, where the carrier-based implementation usually presents a lower computation complexity. In this paper, a novel approach for the carrierbased implementation of different existing PWM methods is proposed for ...

The proposed system is to utilize the renewable resources by digital PWM control of synchronous converter. Usually PWM pulse is being generated through a digital system such as microcontroller or Digital signal controller. In stand – alone application these controllers increases the cost but XILINX FPGA based PWM generation reduces the cost. XILINX FPGA is invented by XILINX which is being cons...

A new auxiliary circuit that can be implemented in DC-DC and AC-DC ZVS-PWM converters is proposed in the paper. The circuit is for ZVS-PWM converters used in applications where high-frequency operation is needed and the load current is higher than that of typical ZVS-PWM converters. In the paper, the operation of a new ZVS-PWM converter is described, its steady-state operation is analyzed, and ...

Due to their ability to synthesize waveforms with better harmonic spectrum and attain higher voltages, multi-level inverters are receiving increasing attention in the past few years. The multilevel inverter was introduced as a solution to increase the converter operating voltage above the voltage limits of classical semiconductors. In this paper, a Diode Clamped Multilevel Inverter is controlle...

The paper presents the full-order small-signal models of some basic PWM converters (Cuk, Sepic and Zeta) with discontinuous inductor current mode (DCM). The derivation procedure is based on the small-signal PWM switch model in DCM and converter topologies derived from their original topologies. The small-signal characteristics of these converters are presented in symbolic forms. Such models can...

We present a goal-seeking framework for decision-making to empower personal wellness management (PWM). PWM is a complex issue that lies at the intersection of multiple disciplines including psychology, exercise science, medicine, behavioral management, nutrition, and emerging technologies. Ultimately, the objective for the PWM enterprise is to encourage participants to become intrinsically moti...

To reduce the high-order harmonics produced by the high-power pulse width modulated (PWM) converters, selective harmonic elimination (SHE) scheme is commonly used due to its superior harmonic performance at low switching frequency. This Project proposes an active compensation method through the PWM control of SHE phase angle. An application example on a high-power PWM current-source rectifier (...

This paper presented a closed loop control of asymmetrical PWM full bridge converter; Renewable energy and distributed generation are getting more and more popular, wind turbines, and fuel cells. The renewable energy sources need the power electronics interface to the utility grid because of different characteristics between the sources and the grid. No matter what renewable energy source is ut...

BACKGROUND Individuals with reading disability or individuals with autism spectrum disorder (ASD) are characterized, respectively, by their difficulties in reading or social communication, but both groups often have impaired phonological working memory (PWM). It is not known whether the impaired PWM reflects distinct or shared neuroanatomical abnormalities in these two diagnostic groups. METH...

OBJECTIVES To explore whether people's organ donation consent decisions occur via a reasoned and/or social reaction pathway. DESIGN We examined prospectively students' and community members' decisions to register consent on a donor register and discuss organ donation wishes with family. METHOD Participants completed items assessing theory of planned behaviour (TPB; attitude, subjective norm...
