this paper describes the design of full bridge DC to DC converter 3 phase six legs for solar PV. The prototype is built with 5 kHz transformers, 2 lead-acid batteries with each energy storage of 12V, 7.2Ah and 20WP solar PV. Three phase switching is provided by analog op-amp comparator circuit with variable frequency 1 kHz-20 kHz. The controller of the converter use adjustable DC power supply as voltage reference for analog op-amp comparator, works varies from 0-11VDC (0%-50% duty cycle) and controlled manually

Generation Capacity

Wind and solar PV have become the lowest-cost alternatives for power generation in many countries and are expected to dominate the renewable power supply in many regions of the world. The temporal volatility in power production from these sources leads to new challenges for a stable and secure power supply system. Possible technologies to improve the integration of wind and solar PV are electrical energy storage and the flexible power provision by bioenergy. A third option is the system-friendly layout of wind and solar PV systems and the optimized mix of wind and solar PV capacities. To assess these different options at hand, a case study was conducted covering various scenarios for a regional power supply based on a high share of wind and solar PV. State-of-the-art concepts for all the stated technologies are modelled and a numerical optimization approach is applied on temporally-resolved time series data to identify the potential role of each option and their respective interactions. Power storage was found to be most relevant in solar dominated systems, due to the diurnal generation pattern, whereas bioenergy is more suitably combined with high wind power shares due to the less regular generation pattern. System-friendly wind and solar power can reduce the need for generation capacity and flexible options by fitting generation and demand patterns better.

In the wireless sensor nodes integrated with the solar PV micro-power supply, the solar energy conversion efficiency and utilization efficiency directly determine working life and stability of the wireless sensor nodes. Thus, a novel solar PV micro-power supply is designed which four solar cell arrays with same open voltage are designed and they are placed in top and three sides of the wireless sensor nodes. Simultaneous, the optimal voltage control technology is used to control work voltage of four solar cell arrays in the design. In addition, the prototype of wireless sensor node integrated with the solar PV micro-power supply is done. Moreover, the working characteristics of the prototype are tested in natural condition. The working voltages of four solar cell arrays are controlled in range of optimal voltage, and the solar cell arrays have high conversion efficiency. The output energy of system is increased about 50% by adding side solar cell arrays.

Switched Capacitor Converter

The study of single phase Switched Capacitors Multi Level Inverter (MLI) is used with Switched Capacitor Converter (SCC) units. The SCC is used to increase the input DC voltage by connecting capacitor in string and shunt. This increassed DC link voltage is converted in to multilevel i.e. 49 level AC output. This SCMLI topology is used to reduce the number of switches, diodes, isolated dc power supply and Total Harmonic Distortion (THD). The SCMLI provides 49 level output voltage using 14 power switches and 3 isolated power supply. The performance of the SCMLI topology is confirmed by using MATLAB simulation result
