A new concept, the multi level voltage/current reinjection is described in this paper. A voltage source converter is proposed, in which the multistep output voltage waveform is achieved by the reinjection of different DC voltage levels via the common neutral point of the converter bridges an 84-pulse voltage source converter (VSC), assembled by combining one twelve-pulse VSC, in conjunction wit...

Power dissipation is a major bottleneck for emerging applications, such as implantable systems, digital cameras, and multimedia processors. Each of these applications is essentially designed as a analog/mixed-signal systemon-a-chip (AMS-SoC). These AMS-SoCs are typically operated from a single power-supply source which is a battery providing a constant supply voltage. In order to reduce power d...

Original scientific paper Measurement of grid voltage harmonic components is an important part of power quality measurements. Current high voltage transformers with iron core are not linear and cannot easily be used for accurate measurement of "polluted" voltages in wide frequency range. In this paper, design details of a new coreless voltage transformer for power quality measurement are given....

This paper introduces a distributed, self-organizing approach to load control based on voltage measurement. A local voltage measurement defines a Level of Service (LoS), which is balanced with the neighboring households in order to avoid extreme restrictions of energy use in a single household. The approach distinguishes four criticality classes for devices which suspend themselves at specific ...

This paper deals with simulation of multilevel inverter based DVR. The DVR circuit produces high quality voltage since it uses a nine level inverter. This DVR gives better solution to the voltage sag problem by injecting a voltage with reduced harmonics. DVR controls the voltage applied to the load by injecting voltage of proper amplitude and phase angle. Thus DVR is responsible for restoring q...

The purpose of this project is to lower the power consumption by reducing the operating voltage of a 32-bit adder, implemented with TSMC035 technology. The delay and power dissipation of the circuit at different voltages were studied and based on the power delay product an optimal voltage of operation was chosen. A level converter circuit was designed, in order to make the circuit compatible wi...

Full power rating three-level neutral-point clamped (3L-NPC) back-to-back power converters seem promising for wind turbine systems with high power. Direct Model Predictive Control (DMPC) is an attractive technique, in particular, for multi-level converters. Voltage sensorless control makes the voltage measurements obsolete. This work proposes and verifies an Initial Bias Compensation based Virt...

A single series resonant converter has been designed to balance the voltage level of a storage battery for electric vehicles. The proposed design has been simulated and verified by using two 100F supercapacitors instate of the conventional rechargeable battery. A voltage monitoring circuit detects the voltage condition of the individual capacitor and sends the voltage status to the control circ...

In this work a new embedded negative voltage level converter is presented. The proposed circuit converts a positive input signal to a negative output signal obtaining an increased protection by the high voltage stress on the used MOS devices. This results in higher system reliability in applications where negative pulses are required. The circuit has been designed in a 0.18μm triple-well standa...

This paper proposes a novel dc-dc converter called the dc-dc multilevel voltage multiplier (mvm). In general, an nx mvm can be built by using two switches, 2n-2 diodes and 2n-2 capacitors, free of magnetic components. It is based on the multilevel converters principle and designed for unidirectional power transfer applications. Each device blocks one voltage level, therefore high voltage conver...
