In this paper, a Quasi-Z-Source Photovoltaic (PV) Inverter is proposed. The proposed inverter gives the solution for most of the problems associated with currently available PV inverters. In this inverter, the power conversion takes place in a single-stage itself thereby fulfilling the requirements such as, inverting dc voltage to proper ac, stepping up the input voltage, maximum power point tr...

This paper presents an improved control strategy for parallel inverters so as to better manage power sharing among the distributed generation units in a microgrid. The proposed control strategy combines both power and voltage control schemes implemented on the voltage source inverters which are used as power electronics interface systems for conversion of power generated by fuel cell and photov...

Synchronization has gained attention in science recently. In electrical engineering, a power network requires generators and loads to be in synchronization. The increase in distributed dc power sources without sophisticated controls has made synchronization more difficult. This paper proposes a synchronous inverter designed for linking distributed power sources within a power network. The linka...

The Adjustable Speed Drives (ADS) are generally used in industry. In most drives AC motors are applied. The standard drives used are Induction Motors (IM) and recently Permanent Magnet Synchronous Motors (PMSM) are also used. Developments in power electronics and semiconductor technology have lead to improvements in power electronic systems. Different circuit configurations namely multilevel in...

This paper proposes a family of novel enhanced-boost quasi-Z-source inverters (EB-qZSIs). For the similar input voltage and shoot-through duty ratio, to that Z-source inverter/enhanced-boost qZSIs, presented topologies provide very high boost at modulation index with improved quality output waveform. Compared EB-ZSI EB-qZSIs, these less capacitors stress, which reduce volume cost system. Akin t...
