POWER QUALITY ENHANCEMENT BY COMPENSATING CUSTOM POWER DEVICES
INTRODUCTION

 The term power quality refers to maintaining a sinusoidal waveform of bus voltage at rated voltage and frequency.
 Over the last 20 years the number of PQ problems are experienced in industrial and commercial sites are increased dramatically.
 The waveform of electric power at generation stage is purely sinusoidal and free from any distortions. There are many devices the distort the waveform tha ....etc

Abstract
In this paper, the method of triangular carrier
switching control of two-level inverters is extended to cascaded
multilevel inverters using phase-shifted multicarrier unipolar
pulsewidth modulation (PWM). The condition for smooth modulation
is obtained using the Bessel’s function representation of
the PWM output and the switching condition of the multilevelinverter-
controlled system. A method is proposed for the determination
of the minimum amplitude of the triangular carrier
for smooth modulation at fixed switchi ....etc
