The input voltage of battery charging system is always above the battery nominal voltage and it should be remained constant. But it depends on the type of input voltage sources. A battery charged directly by photovoltaic (PV) module as the input voltage source can cause the output voltage of PV module or the input voltage of battery charging system can fluctuate, because the output voltage of PV module depends on the solar irradiance. This problem can be solved by installing DC-DC boost converter between the PV module and battery. This paper presents a DC-DC boost converter based on PID controller for battery charging system. It is designed for the input voltage of 12V and output voltage of 14.7V system because it is applied to charge a 12 V, 7 Ah lead acid battery. Based on the simulation result of battery charging system shows that the output voltage of DC-DC boost converter can be remain around 14.7 V. It is due to the PID controller can damp the voltage oscillation and remain its steady state voltage. The time needed by the DC-DC boost converter to charge the battery in the fully charging condition is 1 hour: 3 minutes: 37seconds.

Wireless power transfer (WPT) is a concept to transfer electrical power from a sending coil to a receiving coil without wire. The previous researchers have studied about the WPT using its implementation in simulation modelling, but it is little supporting that related to the mathematical formulation, especially in the distance between the sending and receiving coil. This paper presents a simulation modelling of WPT system using MATLAB SIMULINK based on the mathematical formulation that related to the inductance of inductor of the sending and receiving coil, turn number of coil and mutual inductance as representative of the distance between the sending and receiving coil. The simulation results show that 5 kHz pulse wave generated by pulse generator drives the gate terminal of MOSFET that converts the DC voltage to be 5 kHz AC voltage on the sending coil by the half bridge inverter circuit. The sending coil generates its rms AC voltage of 46.87 V for the distance of 50 cm and also an AC voltage is inducted on the receiving coil with its rms voltage, current and power are 22.79 V, 2.15 A and 10.68 W, respectively.

Design of multiple Pulse Width Modulation (MPWM) Transformerless Photovoltaic Inverter (TPVI) system

2020-01-07 , Alam H. , Muhammad Irwanto Misrun , Mohd Yusoff Mashor , Masri M.

A normal inverter always uses a transformer. By presenting a transformer in the inverter causes its size, losses and efficiency to be relative big, high and low, respectively. An alternative to remove the transformer is very important to solve the problems, but it is still has good performance, especially in the required power quality. This paper presents a design of multiple pulse width modulation (MPWM) transformer less photovoltaic inverter (TPVI) system. It consists of a full bridge inverter circuit, a photovoltaic (PV) voltage storage circuit, a pulse driver circuit, and a circuit of LC filter. An experimental setup is conducted to observe the performance of MPWM TPVI system. The result shows that its performance depend on the solar irradiance and temperature because it operates directly on the sunny day.

Solar Radiation Estimation Using Discriminate Analysis Algorithm for the Output Voltage of Photovoltaic Module

2021-06-11 , Muhammad Irwanto Misrun , Ismail B. , Nisja I. , Irwan Y.M. , Alam H. , Nor Hanisah Baharudin , Jufrizal , Leow W.Z. , Ahmad S.

A study of solar radiation in one area is very important to decide the area is suitable or not to be constructed the generation of photovoltaic (PV) system. The solar radiation can be recorded using the equipment of solar power meter or weather station. But it is due to the limitation of equipment, maybe a technical error occurs on the equipment, thus the equipment has a problem to record the data of solar radiation or one area has no equipment of solar radiation recording. An estimation method of solar radiation is needed to solve the problem. This paper presents an estimation of solar radiation using discriminate analysis algorithm (DAA) that it is applied to the output voltage of PV module. The data of daily measured solar radiation, maximum and minimum temperature are obtained from Chuping Weather Station through the web of world weather online for the year of 2019. The maximum and minimum temperature are as predictor variables in the DAA to obtain the daily estimated solar radiation. The result of daily estimated solar radiation is applied to the output voltage of PV module and compared to the output voltage of PV module applied by the daily measured solar radiation using the statistical analysis, they are root mean square error (RMSE) and error percentage. The results show that the estimated and measured solar radiation have RMSE of 0.257 and error percentage of 1.649%. They indicate that the DAA is acceptable to estimate the solar radiation.

Performance of Nine-Level Transformerless Photovoltaic Powered Inverter (TPVPI) Using Technique of Equal Maximum Phase Delay Time

2020-06-17 , Muhammad Irwanto Misrun , Gomesh N. , Baharuddin Ismail , Alam H. , Masri M. , Kusuma B.S.

A simple inverter is constructed by some switching components that connected in half bridge or full bridge circuit. The switching component can be a metal oxide semiconductor field effect transistor (MOSFET), transistor or insulated gate bipolar transistor (IGBT) which is driven by simple technique of pulse wave modulation (PWM). This technique generates a square alternating current (AC) waveform but it is still AC pulse wave with rich harmonic production and it is not good for the long life of electric devices. A multilevel inverter is better than the previous inverter. Some techniques have been developed to generate multilevel inverter for main objective to generated AC waveform toward sinusoidal waveform and reduce the harmonic. Also, an inverter is constructed by a transformer which is big in size and produce losses and it can increase the harmonic. This paper presents a nine-level transformerless photovoltaic powered inverter (TPVPI) system using technique of equal maximum phase delay time. It is constructed by two main elements. The first is photovoltaic (PV) module as a main direct current (DC) voltage source and the second is four full bridge circuits in cascaded connection. The proposed technique is that each two MOSFETs for cross position in the same full bridge have a same pattern of pulse wave for the period of 0.02 s. It has a phase delay time of 0.00111 s for generating the nine-level AC 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

2022-05-01 , Muhammad Irwanto Misrun , Gomesh N. , Irwan Y.M. , Ismail B. , Leow W.Z. , Hardi S. , Saleh K. , Alam H. , Suwarno

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.
