In this paper, a voltage-current mode controller is proposed to adjust both the input current and DC voltage of a boost-inverter in order to improve the performance of the photovoltaic (PV). The proposed system is based on fuzzy-making-decision predictive voltage-current controller (FPVCC). The simulation results show that in case of using the proposed FPVCC, the input current of a PV array is ...

The matrix converter (MC) for motor drive applications and energy conversion systems is steadily increasing due to its main advantage of performing a direct coupling between two three-phase alternating current sources without the need of an intermediate direct current bus.

In modern electrical distribution systems harmonic distortions are created from a number of sources such as variable frequency drives, lighting, computers and nonlinear loads. Such harmonic distortions produce a variety of undesirable side effects ranging from poor power factor, motor failure to overloading of transformers and conductors. Now a days increasing number of renewable energy systems...

In recent scenario many appliances requires DC power supply. Hence to obtain the DC power from input ac supply, Power Electronics circuits like Rectifiers which is a non-linear load has to be used. The current drawn by these non-linear load will be phase will not follow the supply voltage (i.e non sinusoidal). This results in a High Total Harmonic Distortion (THD) and Low Power Factor (PF).
