A ripple current minimisation based single phase PWM inverter
This paper is aimed at improving the output voltage waveform of a single phase PWM inverter. Two approaches is proposed, the first approach is based on selected harmonic elimination (SHE) of order up to 7th harmonic, for minimising harmonic distortion and modulating amplitude of the fundamental component of the output voltage waveform. For the first time, the Levenberg–Marquardt algorithm (LMA) ... Read more

New High Voltage Gain Dual-boost DCDC Converter for Photovoltaic Power Systems
This article presents a new circuit topology of a high-voltage step-up boost DC-DC converter for photovoltaic power systems. The converter boosts the low-output voltage of the solar cell to the required voltage for the load. The proposed circuit has various advantages compared to the conventional boost converters, namely a higher boost rate with low duty cycle, lower voltage stress on ... Read more

Energy Management of PV/ Wind /Diesel and Battery Hybrid Power Systems
ABSTRACT­­­- This paper presents an energy management strategy for energy storage battery in a standalone hybrid power system. The hybrid system consists of PV generator, wind turbine, storage battery, and inverter. The PV and Wind are the primary power sources of the system, and a battery bank and diesel engine are used as a backup system. An overall energy management ... Read more

ABSTRACT: This paper proposes a novel high step-up DC-DC converter with coupled-inductor and voltage multiplier circuits. The proposed converter achieves high step-up voltage gain with appropriate duty ratio and low voltage stress on the power switch. Also, the paper demonstrates the design of photovoltaic system and operation at Maximum Power Point Tracking (MPPT) of PV array on its characteristics curve. ... Read more
