“…Traditionally, synchronization of grid connected DC/AC inverters is done by duplicating the grid voltage in a way that grid voltage and output current reference are in the same phase [91]. This technique is simple; however, it has a number of disadvantages.…”

This paper gives an overview of previous studies on photovoltaic (PV) devices, grid-connected PV inverters, control systems, maximum power point tracking (MPPT) control strategies, switching devices and transformer-less inverters. The literature is classified based on types of PV systems, DC/DC boost converters and DC/AC inverters, and types of controllers that control the circuit to ensure maximum power tracking and stabilization of load and input voltage. This is followed by the theoretical background of PV devices, an overview of MPPT controllers and common mode leakage current, and a detailed investigation of different inverter topologies regarding the ground leakage current. Furthermore, design principles of power converters, such as DC/DC boost converters, and single-phase inverters are discussed. The paper also discusses limitations and benefits in addition to the basic operating principles of several topologies. Finally, the proposed system is derived and its simulation results are discussed to offer the next generation of grid connected PV systems.

“…e front-end converter of the micro inverter needs to track MPP of the PV module. 3.10c with center tapped winding and reduced active power switches [38]. Similar to the micro inverter topologies discussed above a buffer capacitor has to be placed at the input side of the front end converter of these topologies as well in order to mitigate double line frequency power ripple.…”

“…The cycloconverter is controlled to produce line frequency sine wave current to feed the utility line. Cycloconverter can be high frequency or line frequency switched depending upon the pattern of the voltage/current input to the cycloconverter, which depends on the method of modulation adopted, either the HF inverter or cycloconverter [7,[24][25][26].…”

This paper compares and evaluates two currentcontrolled interfacing schemes for integrating renewable energy sources to a single-phase utility/grid using multi-stage high-frequency (HF) transformer isolated power conditioning system. Operation, merits and demerits are discussed for each scheme with operating waveforms. Several features e.g., utility line power factor, line current THD, size of power electronics system, ease of connection to utility line and simplicity of control, risk of transformer saturation, losses and components ratings in power electronics system, high power density design, and most significantly the size and cost of electrolytic capacitor are compared. Based on their competitive and comparative beneficial features, characteristics of energy source(s), and given specifications, a suitable scheme is justified.
