Title: Multi-Cascaded Inverter Design Using LLC Converter Supplied by a Single PV
Funder: AUSTRIAN INSTITUTE OF TECHNOLOGY GMBH / Electric Energy Systems
Contact: DI. Dr. mont. Kayhan Ince
Project Details: The control system algorithm is performed using the MATLAB Simulink® model. The parameter values of the PID controllers of the system gains and the compensators are derived by PSIM | Software for Power Electronics Simulation. The AC voltage regulation is needed because of the non-linear loads. The entire control system is verified on a single-phase pulse-width-modulation (PWM) converter simulation with a simple DSP-based (C2000 Delfino TMS320F28379D) digital implementation of multi-cascade inverter. The controllers for stand-alone inverter are also tested under non-linear conditions (10 Ohm resistive load, 1mH inductive load and 75mF capacitive load). The PV (Photovoltaic) system controllers consist of two stages, one is for the closed loop control (Implementation of LLC Converter) of the DC-DC stage and the other for the closed loop control of the DC-AC stage. Methods: MATLAB Simulation, Pulse width modulation (PWM)

Title: PV-Anlage (2.0 kWp) an der Türkisch-Deutschen Universität (TDU)
Funder: Türkisch-Deutschen Universität (TDU)
Contact: DI. Dr. mont. Kayhan Ince
Project Details: Die 2.0 kW-Photovoltaik-Anlage liefert Strom für die Universität. Studenten können untersuchen, wie sich die Neigung der PV-Module auf den Energieertrag auswirkt. Theorie ist die Grundlage. Doch erst mit einem Praktikum können sie die graue Theorie um Erfahrungen aus der Praxis ergänzen. Bei TDU ist immer ein Training „on-the-job“: Die Planung und der Bau der Anlage waren für die StudentInnen aus Technik Mechatronischer Systeme besonders spannend. Durch die Arbeit an projektbezogenen Aufgaben, forschen und entwickeln sie selbstständig Aufgaben während des Studiums, die Ihren Fähigkeiten und Kenntnissen entsprechen.

Abstract
Renewable energy resources available locally are ideally suited for providing electricity supply in remote areas. This work describes design and layout of a special single phase supply system with high voltage quality and low power electronics expenditure through application of a special quasi-eight-level inverter output voltage shape with H-bridge circuit configuration. The task is to minimize the number of stochastic and unknown parameters influencing the device functionality. First, the different possibilities to implement a multilevel inverter for grid and its power supply are explored, pointing out the advantages and disadvantages of each solution. Then, a H-bridge-module is designed and built. With these modules and together with some innovative concepts a model of a multilayer inverter is developed and a set of preliminary measurements are gained. The few loads requiring three-phase voltage are motors which shall be driven individually by demand-controlled inverters at corresponding various frequencies and voltages. For the intended application, simplicity is more important than the common approach of higher power transfer capability of three-phase systems. Ideally, the voltage at output side is sinusoidal without harmonics. Practically, we have to find a compromise between voltage quality (that still must fulfill common standards for voltage sags from commutation or switching, and harmonics) and on other side investment in hardware, amount of losses, and robustness. In order to obtain a good voltage shape we may use either high switching frequencies and filter circuits (less than optimum because of additional losses, extra cost and possible resonances to loads), or suitable multi-level inverters which can be realized without filters. Any deviation between ideal sinusoidal shape and actual switched voltage creates a current rate of rise or fall differences to ideal purely sinusoidal current waveform. For a certain current difference the integral of switched minus actual voltage over time is decisive. Finally, the model is validated by practical measurements indicating its correctness.Details
