Investigation of FPGA-based SPWM generator as a control mechanism for a PV/Battery full-bridge inverter  The unipolar SPWM technique produces less harmonic distortion than the Bipolar method, with THD 45% lower  The system implementation of SPWM Pulse generation has been validated on Xilinx Spartan 6 FPGA (XC6SLX45) board using VHDL code. The study presents circuitry modeling and methodology to integrate solar photovoltaic (PV) energy with grid (AC) sources to supplement household appliances during a power cut-off or restricted supply period and alternating charge deep cycle batteries. This paper discusses an FPGA-based Sinusoidal Pulse Width Modulation (SPWM) generator as a control mechanism for a PV/Battery full-bridge inverter. The inverter's efficacy is expressed as the Total Harmonic Distortion (THD) ratio, which must be as low as possible. Various schemes are proposed to reduce THD to generate a more sinusoidal output wave. SPWM is mostly used in industrial inverters. Two SPWM techniques, Bipolar and unipolar, are compared under a variety of Modulation Index (MI) conditions and Carrier Frequency (fc) to analyze the best performance of the full-bridge inverter with less (THD) and smoother output sinewave. The present paper discusses the results of a simulation for a single-phase full-bridge inverter employing bipolar and unipolar SPWM techniques. The output waveform demonstrates that the Unipolar SPWM technique produces less Total harmonic Distortion than the Bipolar method, with THD 45% lower. ISE 14.7 and Matlab 2019 are used to present, simulate SPWM generating code, and implement the design on a field-programmable gate array (FPGA), which acts as a controller for the Mosfet gates in the full-bridge inverter to constitute a sine wave without changing any hardware configuration in the circuit design. The system implementation of SPWM Pulse generation has been validated on Xilinx Spartan 6 FPGA (XC6SLX45) board using VHDL code. The final test on the system design for the SPWM generation program, after synthesis and compilation were finalized and verified on a prototype system.

Gangguan harmonik keluaran tegangan listrik pada inverter dapat menyebabkan peralatan yang terhubung mengalami kerusakan. Inverter konvensional dengan topologi full bridge menggunakan filter pasif untuk mengatasi gangguan harmonik. Namun, membutuhkan nilai komponen yang cukup besar sehingga menambah biaya dan ruang pada inverter. Topologi multilevel inverter (MLI) menghasilkan keluaran yang cukup baik karena bentuk gelombang tegangan keluaran bertingkat dan dapat mendekati bentuk sinusoidal. Selain itu, dengan menggunakan topologi MLI dapat mereduksi biaya dan ruang dari komponen filter pasif. Cascaded H-Bridge MLI menawarkan kinerja yang baik dengan efesiensi daya yang baik, jumlah level tegangan dua kali dari jumlah Separate DC Source (SDCS) dan mudah untuk di desain. Teknik multicarrier SPWM digunakan sebagai pengontrol saklar daya untuk menghasilkan tegangan keluaran bertingkat. Multicarrier SPWM bekerja dengan membanding gelombang carrier bertingkat dengan sebuah gelombang sinusoidal murni. Filter LC tetap digunakan untuk membantu dalam mengatasi gangguan harmonic. Penelitian ini membuat suatu pemodelan Cascaded H-Bridge MLI dan menguji coba dengan menggunakan software MATLAB. Hasil yang diperoleh memenuhi standard persentase THD yaitu 2,09% untuk tegangan dan arus luaran.

This research aims to control the speed of an induction motor by exploiting changes in the fundamental frequency. The inverter as the main part of the variable frequency driver (VSD) uses the IRFZ44n Mosfet as a power switch with a full bridge topology to convert the DC source to AC power. Fundamental frequency manipulation takes place during the conversion process. The method used is to change the variable fundamental frequency of the SPWM signal generated by the Arduino nano to control the power switch. Experiments are carried out based on two stages, namely simulation, and experiment. The simulation is performed using the Pspice A/D Lite software to take time sample data (HIGH and LOW) at each frequency change of 13Hz, 25Hz, 38Hz, and 50Hz, then the sample data is input on the Arduino nano as an SPWM signal generator to control the power switch. The results of the variable frequency drive test are the frequencies generated to drive the induction motor at 12.50 Hz, 24.04 Hz, 35.71 Hz, and 48.54 Hz at motor speeds from 227.7 to 1359.6 rpm.
