Abstract
The Proposed research deals implementation of standalone dynamic solar array fed permanent magnet synchronous motor drive using zero voltage resonant switch converter for the reduction of switching losses and oscillations. The closed loop control voltage strategy has been proposed for power flow management between solar photovoltaic (PV), battery, motor load and to maintain constant load voltage to perform continuous MPPT operation of solar PV. For improving the efficiency and to reduce vibration across the load SPV array fed Zero Voltage Switching (DISOZVS) Resonant Converter with permanent magnet synchronous motor (PMSM) drive is proposed. The DISOZVS resonant converter with suitable switching operation accomplishes for the purpose of reducing the Switching losses. The ZVS converter is constructed by a buck-boost circuit, which is operated as a buck circuit when charging and a boost circuit when discharging. So, we can use many power related systems, which improves efficiency, lower losses and higher performance. The various dynamics and oscillations of standalone SPV array is analysed in the proposed research. The performance of the proposed system is simulated in MATLAB/Simulink atmosphere and various parameters outputs are carried. A hardware prototype of the proposed system has been fabricated for the proposed converter and various analysis were incorporated. The working of the proposed scheme for the different levels of input solar insolation and Load power demand has been satisfactorily demonstrated for both simulation and experimental compared to conventional it results more efficient with reduced losses and oscillations.
Highlights
In recent days Bridling renewable electricity sources such as wind power, sun strength, tidal, and so forth. is essential for overcoming troubles because of international warming and environmental degradation resulting from using fossil fuels
Solar PV is used both in grid linked packages and standalone packages, it may be used in a huge variety of applications from a microwatt Internet of Thinks (IoT) implement to a megawatt scale solar PV plant [1, 2]. solar PV operates in an extensive range of DC voltages, at the same time as electrical and digital structures have different tiers of DC voltage necessities [3].Subsequently, it’s far important to use power electronic interfaces for solar PV packages, for the reason that electricity from solar PV is intermittent in nature, it is necessary to mix electricity storage systems and different renewable electricity assets to maintain reliable operation for standalone PV structures
Unregulated inductor and couple of output DC-DC converters primarily based on equipment size, buck-boost enhance topologies had been proposed in diverse literature [9,10,11,12,13], this reduces the price, circuit complexity and consequences in greater performance
Summary
In recent days Bridling renewable electricity sources such as wind power, sun strength, tidal, and so forth. is essential for overcoming troubles because of international warming and environmental degradation resulting from using fossil fuels. Solar PV operates in an extensive range of DC voltages, at the same time as electrical and digital structures have different tiers of DC voltage necessities [3].Subsequently, it’s far important to use power electronic interfaces for solar PV packages, for the reason that electricity from solar PV is intermittent in nature, it is necessary to mix electricity storage systems and different renewable electricity assets to maintain reliable operation for standalone PV structures. This may be executed through many single input two port DC-DC converters in parallel or multiport DC-DC converters. The related output energy cannot provide individual regulation in a balanced way
