[ 1 ] - A Closed Loop Control of Quadratic Boost Converter Using PID Controller
This paper presents an implementation of open loop and closed loop control of Quadratic boost converter using PID controller. Quadratic boost converter consists of boost converter and fly back converter driven by a single switch. Quadratic boost converter QBC is designed especially for regulating the DC interface between various micro sources and dc-ac inverter to electricity grid. Quadratic b...
[ 2 ] - A Robust STATCOM Controller using Particle Swarm Optimization
In this paper, a statcom without any energy storage devices is proposed to compensate network voltage during disturbances. This statcom utilizes a matrix converter in its topology which eliminates the DC-link capacitor of conventional statcom. The modulation method for matrix converter which is used in this paper is space vector modulation. There are some methods to improve power quality for se...
[ 3 ] - Harmonic Reduction Technique Using Flying Capacitor Based Z Source Inverter for a DVR
The Dynamic Voltage Restorer (DVR) is a commercially available, popular device to eliminate voltage sags and swells in the distribution lines. Its basic function is to inject the voltage difference (difference between the pre-sag and sag voltage) to the power line and maintains the pre-sag voltage condition in the load side. The efficiency of the DVR depends on the performance of the efficiency...
