A novel triple-band circularly polarized printed crossed dipole antenna is proposed. Circular polarization (CP) in the antenna is achieved by feeding the orthogonal dipole arms with 90o phase difference using vacant quarter printed ring. Loading of the dipole arms with interdigital capacitor (IDC) of suitable parameters provides the triple band CP operation. The effects of variation in the parameters...
Distribution static synchronous compensator (D-STACOM) has a greater importance in modern distribution level for reactive power compensation dynamically and power quality improvement. In this paper an effort has been given to design a D-STATCOM, an essential shunt Flexible AC Transmission Systems (FACTS) device using decoupled current control method for three phase three wire system to compensate...
The multicell converter is used to enhance the converter rating and improve the power quality on input AC side. The conventional multicell AC-DC converter with fixed hierarchy of H-bridge cells leads to unbalanced voltages across the DC side of the cells. This paper presents a hierarchal hysteresis current controlled cascaded H-bridge multicell AC-DC converter. The problem of unbalanced voltages has...
