SPWM or sinusoidal pulse width modulation is widely used in power electronics to digitize the power so that a sequence of voltage pulses can be generated by the on and off of the power switches. The pulse width modulation inverter has been the main choice in power electronic for decades, because of its circuit simplicity and rugged control scheme SPWM switching technique is commonly used in industrial applications SPWM techniques are characterized by constant amplitude pulses with different duty cycle for each period. The width of this pulses are modulated to obtain inverter output voltage control and to reduce its harmonic content. Sinusoidal pulse width modulation or SPWM is the mostly used method in motor control and inverter application. In this development a unipolar and bipolar SPWM voltage modulation type is selected because this method offers the advantage of effectively doubling the switching frequency of the inverter voltage, thus making the output filter smaller, cheaper and easier to implement. Conventionally, to generate this signal, triangle wave as a carrier signal is compared with the sinusoidal wave, whose frequency is the desired frequency. In this paper single-phase inverters and their operating principles are analyzed in detail. The concept of Pulse Width Modulation (PWM) for inverters is described with analyses extended to different kinds of PWM strategies. Finally the simulation results for a single-phase inverter (unipolar) using the PWM strategies described are presented

This paper presents the PSIM simulation of single phase unipolar sinusoidal pulse width modulation (SPWM) inverter with load voltage regulation. From the point of view of minimization of current distortion, inverter switching strategies can be classified in to two categories; one is unipolar current controlled inverter and another is the bipolar current controlled inverter. Unipolar switched inverter offers reduced switching losses and generates less electromagnetic interference (EMI). The SPWM technique is used to produce pure sinusoidal wave of output voltage and current. The control circuit itself generates the required pulse according to the load demand, to get variable output voltage from the inverter by changing the modulation index of unipolar SPWM scheme.

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.

Introduction: In 2020, the World Health Organization announced that Corona virus (Covid-19) is a global pandemic. Since then, social distancing and sterilization have become essential as precaution measures to decrease the infection. The risk of Covid virus spread led people, industries as well as governments to implement several approaches to control the transmission rate of the virus. During their daily life activities such as work, shopping, eating, etc. people touch a lot of surfaces and also open a large number of doors. This is considered to be one of the fastest ways to spread viruses because many people touch door handles which are generally rarely cleaned. Method: In this paper, the implementation of a cost-effective smart device has been presented. The device sprays ethanol onto a doorknob from an ethanol sterilizer after any person touches the knob. The sensor detects a hand touching the knob, after that a signal is sent to the Arduino for processing, and then after a 4.5...
