The proposed converter is operated at a duty cycle D = 0.6 and a high voltage conversion ratio of 17.5 which is ideal for sustainable energy applications. This paper uses the proposed converter for a grid-connected solar PV system with an NPC inverter controlled using Space Vector Pulse Width Modulation (SVPWM) technique.
The output voltage of converter is converted into a variable alternating voltage and variable frequency by three phase three-level NPC Inverter. The space Vector Pulse Width Modulation (SVPWM) method technique is utilized for generation of switching pulses for NPC inverter.
A grid-connected PV system employs the suggested DC converter with a three-phase-three-level NPC inverter controlled by the SVPWM strategy. The stepped output voltage from the NPC inverter is filtered to improve power quality and then coordinated with the grid. The remaining sections of the paper are organized as follows.
For the generation of SVPWM based pulses for NPC inverter, VHDL with Xilinx-ISE programming language is chosen. From the simulation and hardware results, the proposed structure can increase the PV input voltage and inject power into the grid through Neutral-Point-Clamped (NPC) Inverter.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
