Single phase unified power quality conditioner (UPQC) consists of series and shunt active power filter (APF) with common dccapacitor. Series converter acts as voltage source converter and shunt converter acts as current source converter. Use of non-linear loads results in voltage and current harmonics. These harmonics can be eliminated by using single phase UPQC. So that, which also improves th...

Received Jan 17, 2017 Revised Mar 17, 2017 Accepted Mar 31, 2017 Brushless DC motor is a synchronous machine that makes use of electronic commutation instead of mechanical commutator. Brushless DC motors makes use of inverter encompassing static switches for its operation. A simple bridge converter when used for BLDC drive as front end converter makes input source power factor to get reduced wh...

DC-DC converters, common in battery-driven, portable, and other high-efficiency systems, can deliver efficiencies greater than 95% while boosting, reducing, or inverting supply voltages. Resistance in the power source is one of the most important factors that can limit efficiency. This application note describes the effects of source resistance, how to calculate efficiency, real-world considera...

This paper describes a new design for direct sliding mode method with a high switching frequency using the PD-PI type sliding surface applied to a negative output Luo converter worked in continuous current mode for applications required constant power source such as aerospace applications, medical equipment and etc. Because of the output power and line changes, the converter model is also nonli...

345 Abstract—In this paper Static Synchronous Compensator (STATCOM) is used for voltage stability and the compensation of reactive power. The STATCOM contains an Insulated Gate Bipolar Transistor (IGBT) based voltage source converter for voltage control and reactive power compensation. The STATCOM is used to control the reactive power with the voltage source converter in combination with a DC v...

Multi-port converter with three active full bridges, two series-resonant tanks and a Multi-winding transformer is proposed. It uses a single power conversion stage with high-frequency link to control power flow between batteries, load and a renewable source such as fuel cell. The converter has capabilities of bidirectional power flow in the battery and the load port. Use of series-resonance aid...

The KY Converter, Which is a step up converter, The name given to this converter is first letter of the authors, K.I. Hwu, Y. T. Yau. This converter always operate in CCM, and the output current is non-pulsating, and low output voltage ripple and higher voltage boosting capability. In this paper, different modes of KY Converters are studied. The simulation is carried out to study the perfomance...

Voltage-Source Converters have brought numerous advantages to HVDC transmission. However, they suffer from high losses and are usually weak against faults on the DC-side. In this paper, a new topology which brings together some concepts from traditional Current Source Converters and multi-level converters, is presented. Two stacks of Hbridge cells alternate to construct the converter voltage us...
