Zero-Voltage Switching High Efficient DC Motor Drive

A half-bridge ZVS-PWM converter with complementary switch is described in this paper. Zero Voltage Switching is analyzed taking into account the effect of the leakage inductor of transformer. The main advantages of this converter, that are high efficiency for low output voltage, soft-switching for primary and very small pulsation for DC motor, are shown in a simulation

FACTS controller design for improving Power System damping

This paper presents a control system design for the STATCON of FACTS devices by LQR, LQG control scheme to enhance small-signal stability in the power system, the feature of this FACTS controller is coordinated with generator exciter controller(AVR, PSS) to improve the total power system stability and performance

1MVA Distribution STATCON for Flexible AC Transmission System (FACTS)

The availability of high power IGBT has led to development of controllable reactive power and harmonics compensation source for use in power transmission system. The paper describes the fundmental operating principles and several application examples. The control technique of reactive power and harmonics compensation for Distribution STATCON is presented, and the computer simulation results are shown to show the effectiveness of tile proposed control technique
