Extended family of DC-DC Quasi-Z-Source converters

Family of multiport bidirectional DC-DC converters

Multiport DC–DC converters are of potential interest in applications such as generation systems utilising multiple sustainable energy sources. A family of multiport bidirectional DC–DC converters derived from a general topology is presented. The topology shows a combination of DC-link and magnetic coupling. This structure makes use of both methods to interconnect multiple sources without the pe...

Application of PWM Control Strategy on Z-Source Isolated Dual active bridge DC-DC Converters

DC-DC Power Converters

Dc-dc power converters are employed in a variety of applications, including power supplies for personal computers, office equipment, spacecraft power systems, laptop computers, and telecommunications equipment, as well as dc motor drives. The input to a dc-dc converter is an unregulated dc voltage Vg. The converter produces a regulated output voltage V, having a magnitude (and possibly polarity...

Design and Implementation of Step Up DC-DC Converter with a Cascaded Quasi-Z Source Network

This paper proposes a new topology of quasiZ-source inverter(qZSI) which is used as step-up isolated dc/dc converter for residential fuel cell (FC) power systems .The proposed topology used is cascaded quasi Z source inverter and implemented using induction motor. The cascaded qZSI is derived by the adding of one diode, one inductor and two capacitors to the traditional qZSI. The proposed two-s...

Control of DC-DC Converters

A constant voltage regulator, to supply constant power loads, is realized using a Switched-capacitor converter. Exhaustive studies have been carried out to find the suitability of available control schemes and finally one control scheme investigated with (i) operation of the converter at different crossover frequencies (ii) operation of the converter at different phase Margins. Various operatin...
