Inverters installed in the photovoltaic (PV) powered uninterruptible power supply (UPS) system consist of battery and also PV module. An optimum number of PV module and battery should be considered to reduce costs and technical works. The PV powered UPS system is operated directly by the PV module, therefore, an optimization sizing of PV powered UPS system should be studied in terms of optimum PV module number that related to the power capacity of PV powered UPS system, solar radiation and temperature. This paper presents an optimum sizing of PV powered UPS system application. A mathematical modeling is created to obtain the optimum number of PV module and battery. The result shows that for 12V, 100W PV powered UPS system applying the 60W, 21V PV module, 12V, 100Ah battery, 700W AC load power, thus, the optimum number of PV module and battery are 20 modules and 5 pieces, respectively.

Effect of temperature and solar irradiance on the performance of 50Hz photovoltaic wireless power transfer system

2023 , Muhammad Irwanto Misrun , Yoga Tri Nugraha , Indra Nisja , Nuriziani Hussin

A wireless power transfer (WPT) system transfers an alternating current (AC) power from a TC (transmitter coil) to a RC (receiver coil), using an electromagnetic field concept. Several previous reports on WPT systems were able to transmit this power, although their AC frequencies were high in some kilohertz or megahertz (kHz or MHz). These frequencies were unable to be applied directly on the AC loads or only administered to the direct current (DC) energy after rectification through a rectifier circuit. In the receiver phase, the AC power was also very low, due to the minimum voltage and current on the RC. Therefore, this study aims to determine the effects of temperature and solar irradiance on the performance of the 50 Hz photovoltaic wireless power transfer (PVWPT) system. This system is constructed by some PV modules in series connection, to achieve a required DC voltage level on the DC-DC converter and receiver phase. It also converts DC to AC voltages on the TC (transmitter coil) of an H-bridge inverter, with a receiver circuit and a magnetic relay coil positioned between the TC and RC (transmitter and receiver coil). The results showed that solar irradiance and temperature affected the performances of the PV module and PVWPT system. This indicated that higher solar irradiance increased the performance of the PVWPT system, whose maximum efficiency was achieved by positioning the magnetic relay coil between the TC and RC.

Normally, the magnetic field density in a solenoid is generated by a constant DC current source. A photovoltaic (PV) module is also a DC current source. The output current of PV module depends on the solar irradiance and temperature. The PV module generates a higher current on the constant temperature and higher solar irradiance. Inversely, it generates a lower current on the constant temperature and lower solar irradiance. Thus, it is important to study the output current of PV module related to the magnetic field in a solenoid. The daily data of solar irradiance and temperature are recorded by Vantage Weather Station Pro2 in Universiti Malaysia Perlis (UniMAP) throughout the year 2015. The performance of PV module (maximum peak point current) is simulated using PSpice software. The daily maximum peak point current of PV module is applied into a formulation of magnetic field density to obtain the daily maximum magnetic field density generated in a solenoid. The result shows that the higher maximum peak point current generated by PV module will produce the higher magnetic field density in a solenoid.

Analysis of AC voltage and current waveform distortion on SPWM transformerless photovoltaic inverter

2017-10-01 , Muhammad Irwanto Misrun , Hermansyah Alam , Mohd Yusoff Mashor , Mahrizal Masri , Haziah Abdul Hamid , Baharuddin Ismail , Butar-Butar A.H.

Normally, the low frequency (50Hz) inverter uses a transformer that is bigger in size, heavy and expensive. For reducing the size, weight and manufacturing cost, the SPWM TPVI is suitable, it can generate a sinusoidal AC waveform which is suitable for the long life of AC loads. This paper presents an analysis of AC voltage and current waveform distortion on sinusoidal pulse width modulation (SPWM) transformerless photovoltaic inverter (TPVI). The sinusoidal waveform is developed based on the SPWM technique by installing an LC filter at the end terminal of full bridge inverter. It is due to no optimum value of LC components and AC load, whereas the AC voltage and current waveform will be distorted. Thus, it is very important to analyze the distortion of AC voltage and current waveform.

The technique of voltage level time division based on maximum pulse width to reduce total harmonic distortion on Multilevel Transformerless Photovoltaic Inverter (MLTPVI) System

An inverter is an important component used to generate alternating current (AC). One of the most common types is the multilevel inverter (MLI), which generates an AC multilevel voltage waveform. This device is designed from a simple topology with the power switching components in the full-bridge circuit connected in a series connection. The circuit consists of a total harmonic distortion (THD), voltage total harmonic distortion (VTHD), and current total harmonic distortion (CTHD). However, creating a suitable MLI technique capable of generating AC multilevel voltage waveform to achieve the lowest harmonic is one of the problems commonly faced. Therefore, this research aims to design a voltage level time division based on maximum pulse width to reduce THD on a multilevel transformerless photovoltaic inverter (TPVI) system. The direct current supplied to this is from the photovoltaic (PV) module. This research also aims to generate the phase delay time and pulse width of waves by proposing a division factor, n, proposed through mathematical modeling and simulated using SIMULINK Matlab. The results showed that the modeled PV is valid to the datasheet, therefore, it is suitable to supply the 11-level TPVI system. Furthermore, the proposed technique has the ability to generate the AC 11-level voltage waveform with different division factors, n. The lowest VTHD and CTHD are achieved at values of 8, respectively.

Normally, an uninterruptible power supply (UPS) system supplies to AC lands if the national utility grid fails to supply AC source to the AC loads. The UPS system stands on the national utility grid. It means that it can be operated only in the area or near the national utility grid.
