Iam a final year b.tech student of EE branch. I hav just started with my project work(Harmonic Reduction in Three phase Parallely Connected Inverter).Iam facing problem in triggering the thyristors using MATLAB,Simulink software as i do not know anything about the MATLAB software. Can anyone please guide me in solving this problem and give information regarding my project? The methods which i want to use to reduce harmonics are:
1.filters
2.transformer connections
3.Pulse Width Modulation(PWM)
4.Third Harmonic Injection Pulse Width Modulati ....etc

H-BRIDGE VSC WITH A T-CONNECTED TRANSFORMER BASED
THREE-PHASE FOUR-WIRE DSTATCOM FOR POWER QUALITY
IMPROVEMENT


I. INTRODUCTION


THE present day ac power distribution systems is
suffering from severe power quality problems. These
power quality problems include high reactive power
burden, harmonics currents, load unbalance, excessive
neutral current etc. . The power quality at the point
of common coupling (PCC) with the utility grid is
governed by the various stand ....etc

Current-Fed Resonant Full-Bridge Boost DC/AC/DC Converter
INDIRECT dc/ac/dc converters utilizing an isolation transformer
are widely used in different applications, such as
battery chargers and dischargers, uninterruptible power systems,
alternative energy systems, hybrid electric vehicles, and
medical X-ray imaging.
In the case of the applications where low input voltages have
to be converted to high output voltages, current-fed converters
are used, whereas in the case of higher power applications, fullbridge
boost conve ....etc

Single-Phase Seven-Level Grid-Connected Inverter
for Photovoltaic System



I. INTRODUCTION
THE ever-increasing energy consumption, fossil fuels
soaring costs and exhaustible nature, and worsening
global environment have created a booming interest in renewable
energy generation systems, one of which is photovoltaic.
Such a system generates electricity by converting the Sun s energy
directly into electricity. Photovoltaic-generated energy can
be delivered to power system n ....etc

Single-phase half-bridge inverter


Operational Details

Consists of 2 choppers, 3-wire DC source
Transistors switched on and off alternately
Need to isolate the gate signal for Q1 (upper device)
Each provides opposite polarity of Vs/2 across the load

DC Supply Current
If the inverter is lossless, average power absorbed by the load equals the average power supplied by the dc source.
For an inductive load, the current is approximately sinusoidal and the fundamental component of the output ....etc
