Sinusoidal Pulse Width Modulation

Abstract The work proposed in this paper focuses on providing an effective solution to shortage of power in rural areas with an effective technique implemented in an economically feasible way. The traditional Inverters used for either residential or commercial purposes consume electrical energy from the grid to fulfill the charging and discharging of the battery, which may lead to overloading. The shortcomings of the traditional inverters such as Non-Renewable nature of power sources, increased cost of manufacturing, and multi-stage conversion complexity, are considered by the researchers for improvement. As a result, an attempt has been made to provide a cost effective renewable energy system with single stage topology for AC power applications. Single stage power conversion with allowed shoot through state is used here to avoid additional components and reduce the switching losses. Unlike the traditional inverters, the Quasi Impedance Source Inverter that is brought forward can be utilized as a Standalone system or a capable backup at the time of power outages. Sinusoidal pulse width modulation (SPWM) is applied to attain reduced harmonics which are measured by observing the harmonic pattern in Total Harmonic Distortion (THD) curve. The lab results obtained through MATLAB simulation confirm the noteworthy diminution of THD level in the proposed system compared to the reported one. Usage of Photovoltaic (PV) Panel to tap energy with reduced stochastic fluctuations due to high filtering capacity of the proposed circuit, eliminating the need of additional filters, is the uniqueness of this technique.

Sinusoidal Pulse Width Modulation

This paper presents simulation and experimental verification of a single stage DC to AC boost inverter for solar photovoltaic (SPV) applications. This topology integrates the boost converter inside the conventional h-bridge inverter topology. This eliminates the need for a separate boost converter. The whole system requires four basic switches of an h-bridge inverter for both boost and DC-AC conversion operation. Overall, the efficiency is improved because no additional switch is required for the boosting operation. The duty cycle variations are implemented using sinusoidal pulse width modulation (SPWM). The firing pulses for switches used in the h-bridge inverter are provided using Arduino-Uno platform. The principle of operation along with the simulation and experimental results are also presented.

Sinusoidal Pulse Width Modulation

Indonesia ternyata tidak sepadan dengan kualitas listrik yang diberikan oleh PT. PLN. Tegangan PLN paling rendah yaitu 170 V yang terdapat di beberapa kota. Tidak tercapainya rating tegangan dapat menyebabkan peralatan elektronik tidak bekerja secara maksimal dan berpotensi mengalami kerusakan. Salah satu tujuan penelitian ini yaitu merancang sebuah konverter sebagai solusi dari permasalahan jatuh tegangan dan kestabilan tegangan, yaitu automatic voltage regulator (AVR) menggunakan inverter 1 fase teknik pemicuan sinusoidal pulse width modulation (SPWM) dengan pengaturan tegangan DC. Topologi pengatur tegangan DC yang digunakan adalah DC chopper buck-boost teknik pemicuan pulse width modulation (PWM) dengan umpan balik di sisi keluarannya.  Perancangan dilakukan berdasarkan ketentuan literatur terkait, simulasi PSIM 9.0 dan MATLAB 2014a. Konverter dengan sistem AVR diharapkan dapat mencapai tegangan rating dan stabil pada level 207 – 241 V sesuai standar SPLN 1:1995. Berdasarkan hasil pengujian variasi tegangan sumber dari 170 – 200 V dengan sistem AVR, konverter dapat mencapai tegangan rata – rata pada sisi DC dan AC berturut – turut sebesar 229,5 V dan 228,56 V dengan frekuensi rata – rata 50,25 Hz. Efisiensi rata –rata yang dapat dicapai oleh konverter sebesar 72,02% pada kondisi sistem AVR bekerja.

Bridge Topologies

Single-phase full-bridge transformerless topologies, such as the H5, H6, or the highly efficient and reliable inverter concept (HERIC) topologies, are commonly used for leakage current suppression for photovoltaic (PV) applications. The main derivation methodology of full-bridge topologies has been used based on both a DC-based decoupling model and an AC-based decoupling model. However, this methodology is not suited to the search for all possible topologies, and cannot verify whether they are inclusive. Part I of this paper will propose a new topology derivation methodology based on unipolar sinusoidal pulse width modulation (USPWM) to search all possible full-bridge topologies for leakage current suppression. First of all, a unified circuit model is proposed, instead of the DC- and AC-based models. Secondly, a mathematic method called the MN principle is then proposed to search for all possible topologies, and a derivation procedure is provided. It was verified that all existing topologies could be found using the proposed method; furthermore, seven new topologies were derived. The proposed topology derivation methodology is extended to search topologies under Double-Frequency USPWM (DFUSPWM). Twenty topologies under USPWM and four topologies under DFUSPWM have been derived.
