<p class="Abstract"><span lang="EN-US">This paper presents a study on the significance of source side harmonics and their effects on transformers.  Source side harmonics are typically present in power electronic sources which are commonly used in renewable applications. The continued outcome of source side harmonics is observed on the hysteresis curve of a transformer. Single-phase transformers are used in the proposed study to determine the effect of harmonics on magnetization and demagnetization cycles using an electronic operational amplifier-based integrator circuit. A technique is also presented for effectively storing and plotting the hysteresis curve from the measured data. After the hysteresis curve is obtained, it is compared with standard data and a conclusion is obtained from the results about the presence of harmonics in the source. The hysteresis curve is thus found without removing the transformer from operation. The study also proposes a modified hysteresis model for the transformer considering the effect of source harmonics. The proposed study is an effective tool for easy measurement and detection of harmonics. The <em>MATLAB/Simulink</em> based simulations with suitable experiments validate the proposed study.<em></em></span></p>

Now day’s the power factor has become a major problem in power system to improve the power quality of the grid, as power factor is affected on the grid due to the nonlinear loads connected to it. Single phase bridgeless AC/DC power factor correction (PFC) topology to improve the power factor as well as the total harmonic distortion (THD) of the utility grid is proposed. By removing the input bridge in conventional PFC converters, the control circuit is simplified; the total harmonics distortion (THD) and power factor (PF) are improved. The PI controller operates in two loops one is the outer control loop which calculates the reference current through LC filter and signal processing. Inner current loop generates PWM switching signals through the PI controller. The output of the proposed PFC topology is verified for prototype using MATLAB circuit simulations. The experimental system is developed, and the simulation results are obtained.

<p class="Abstract"><span lang="EN-US">Across the year, the needs of Indonesians in the use of electronic equipment are increasing, which results in higher electricity usage. Because most of the electricity load uses AC power, in the application of a DC power source such as solar cells, an inverter that converts DC to AC power is needed. Therefore, the inverter is one of the tools that are widely developed in power electronics. The output voltage from simulation and real hardware is a sine wave with some distortion due to lack of filter; therefore, there occurs a harmonic. The voltage and frequency were also measured with a multimeter. The result shows that both voltage and frequency are closed to the design specification which is 220V 50Hz with the voltage and frequency difference of 1.09% and 0.4%, respectively.</span></p>

The article presents a simulation model of a thyristor- reactor switching device (TRSD) created in the Matlab Simulink program. The model of a TRSD single- phase connected to a single-phase transformer has been created, and transients that occur during voltage regulation in a single-phase circuit are considered and analyzed. Supplement was introduced to the method for calculating TRSD thyristors. The developed model of a single phase of TRSD can be used to create models of converter transformers on traction substations with TRSD.

In stand-alone photovoltaic installations the photovoltaic inverter allows transforming the DC power produced by the photovoltaic modules into an AC power. Depending on the shape of the AC output voltage generated by the inverter there exist three main types of stand-alone PV inverters: pure sine waveform inverters, modulated sine waveform inverters and square waveform inverters and each type of these inverters is also divided into different topologies. In this paper we will be interested and study the square waveform stand-alone inverter topologies which are the half bridge and the full-bridge inverter topologies.

In this paper, a single phase dc to ac inverter with a low cost driver circuit was developed. The input source is a battery tank of four series-connected LiFePO4 batteries. The input DC power is then converted into the output AC power with 110Vrms and 60Hz. The proposed inverter is composed of a boost DC converter and a full bridge inverter. As for the circuit architecture, the boost converter is used to boost the battery tank voltage to 190V DC voltage bus. The DC voltage bus is then used to generate the output AC voltage by the full bridge inverter. A low price micro-controller unit HT66F50 was adopted for the controller of the proposed inverter. Moreover, instead of a common switch driver IC, a driver circuit with about 50% cost reduced was constructed for the full bridge inverter. A prototype with 300W rated output power was practically constructed and it can be seen that the total harmonic distortion is lower than 5%.
