The design of PV-based high gain SEPIC converter integrated with four-switch strategy, which has been used to achieve sensorless speed control of Permanent magnet Brushless DC motor (PMBLDC) is analysed in this work. Hence SEPIC converter coupled with Fuzzy Logic, MPPT Algorithm is employed to retain voltage. SEPIC converter is chosen as it has a c...

This paper proposes the reduction of common mode voltage (CMV) magnitude using a simplified logical modulator (SLM). This modulator uses the ideas of space vectors to detect and eliminate the high common mode vectors produced by carrier phase-shifted sine pulse width modulation generator. The proposed SLM has an inherent ability to eliminate the CM...

The conventional sinusoidal pulse width modulation (SPWM) and the space vector PWM (SVPWM) switching techniques are widely used for power converters due to their ability to control the harmonic content of the output voltage. The most popular PWM techniques used in matrix converters are direct space vector modulation (DSVM) and indirect space vector...

The prime focus of this paper is on power factor improvement in a medium transmission line through reactive power compensation using the distribution side - Static Synchronous Compensator (D-STATCOM). A 100 kVA, 11 kV, 80 Km transmission line is taken into consideration and shunt compensation is established through the Vector based Hysteresis Curre...

A Distribution STATCOM (DSTATCOM) is a current controlled Voltage Source Converter (VSC) used for reactive power compensation, when connected to the power system. The DSTATCOM using PI controlled Space Vector Pulse Width Modulation (SVPWM) technique has high peak overshoot and large settling time. SVPWM technique requires Phase Locked Loop (PLL) fo...

A Distribution STATCOM (DSTATCOM) is a shunt compensation device used for reactive power compensation. It can be used either in the power factor correction mode or in the voltage regulation mode. In this paper, a vector based hysteresis current controller (HCC) for DSTATCOM, operated in the power factor correction mode, is implemented. The control...

This paper gives the State Space modeling of Distribution Static Synchronous Compensator (D-STATCOM). It is important to keep the voltage constant in the distribution system, hence voltage regulation is required in the distribution network. Voltage Source Converter (VSC) based D-STATCOM achieves voltage regulation in the connected bus by absorbing/...

Power system generators supply the required active power and part of the reactive power. Insufficient reactive power in the power system affects the bus voltage and sensitive loads connected to them. To keep the bus voltage as per the requirement of the grid code, deficient reactive power should be supplied and surplus reactive power should be abso...

This paper investigates the dynamic operation of Static Synchronous Compensator (STATCOM) based on a model comprising a multilevel 48-pulse Gate Turn-Off thyristor (GTO) voltage source converter for reactive power compensation and voltage stabilization of electric power transmission and distribution systems. Multi-pulse converters are made up from...
