Hybrid Energy Source Fed Fuzzy-Based SVPWM for 5-Level NPC Inverter with Grid Connected System

Abstract

This paper presents the fuzzy-based Space Vector Pulse Width Modulation (SVPWM) for 5-level Neutral Point Clamped inverter with hybrid energy source fed grid connected system. The proposed scheme is energized using Photovoltaic and Wind energy system combination. The Neural Network-(NN) based Maximum Power Point Tracking algorithm (MPPT) has been implemented to track maximum power under different operating conditions. First, we proposed fuzzy-based SVPWM, which is developed for 5-level NPC inverter to provide voltage and current control, reduced THD, predetermined switching pattern, capacitor voltage unbalance minimization and maintain good control under nonlinearities and suspicions of PV-Wind energy connected hybrid system. Second, we proposed the inverter output voltage, which has been synchronized with grid connected system using split inductor (SI). The reference voltages for SVPWM implementation were obtained using feedback current control method. Third, we proposed different solar radiations, the proposed system has attained better performance by trailing maximum power from hybrid energy system. The simulation and experimental responses have been validated using Matlab/simulink and FPGA processor.

Design of vehicle using Ackermann steering with IoT concept

“…This system contains frictional losses and also an offset can be seen but if replaced with electronic system it will get a feedback system and the least count (L.C) of 1/10th of a micron which is very small as an offset [15]. The mechanical gears and nuts can be replaced by industrial grade servo's and an electronic feedback system which takes an Analog input from the steering wheel find the angle of the steering wheel and using the Ackermann's geometry we can find out the angle of rotation of 1433 the wheel and also the radius or curvature of turning for the car and the individual wheels [16]- [18]. The Figure 1 shows the Ackerman steering positioning.…”
