This project’s goal is to create a home automation system utilizing thyristors. As technology develops, homes become smarter.
The suggested system uses cutting-edge wireless RF technology to manage household appliances. In the majority of homes, centralized control systems with RF-controlled switches are replacing conventional switches.
A planar inductor placed beneath a metallic vessel creates a changeable magnetic field, which is the basis on which this system operates.
Using a power supply, the mains voltage is rectified, and the inverter then supplies a medium frequency to feed the inductor. Based on the operational frequency range and output range of up to 3KW, this system uses IGBTs.
By activating a TRIAC in such a manner that the light stays to switch “ON” as the precise time is regulated after detecting the Zero-crossing point concerning the supply-voltage waveforms, the suggested system offers a solution for the failure of random switching of the lamps.

The goal of the project is to enhance the single-phase switch-mode rectifiers’ performance and efficiency through better control. The switch-mode rectifier in this system’s design performs at unity power factor, displays almost any input harmonics, and generates tolerable ripples in the DC bus voltage.
The android application on a smartphone or tablet with a touchscreen-enabled graphical user interface may be used to remotely operate this device.
A Zero detector crossing unit, which detects the output and feeds the result to the microcontroller, is part of this project. The amount of AC power sent to the load can be changed by utilizing a Bluetooth device and an Android application.
This device produces harmonics. Another method is integral cycle switching, which eliminates one whole cycle or a certain number of complete cycles of the AC signal delivered to the load. In this project, a system is designed to use the latter technique for controlling AC power to loads.
The power factor of the AC signal applied to the load is defined in this project, and as a result, thyristors linked back-to-back are utilized to bring capacitors across the inductive load.
Energy production from renewable sources is increasing steadily. Power converters are therefore required for these applications.
There are two types of power converter topologies: single and multiple cells. An evaluation of current power converters is conducted, including some that haven’t been used because of high power danger.
Power electronics have several challenges, one of which is achieving high efficiency on power converters. With the aid of low-voltage components, multilevel converters handle the high-voltage issue. Only capacitive parts are used in the systems of ladder multilevel DC/DC converters. This article compares three of these topologies.

The project’s main goal is to create a flexible device that can use radio frequency to operate DC and servo devices. This notion of wirelessly controlling DC and servo motors is intriguing, and it is widely employed in robotics, business, and toy automobiles.
A viable alternative for many power-related systems, including hybrid and fuel cell vehicles as well as renewable energy systems, is the bidirectional DC-DC converter combined with energy storage.
A very effective and dependable non-isolated bidirectional DC-DC converter solution is put forth. A tiny negative coupled inductor is employed to divide the switch branch of the system into two power flows. Additionally, it stops electricity from passing freely through the MOSFET’s diode.
Due to its attributes, such as easy control, little noise, high power density, high output torque, etc., brushless DC motors are frequently employed.
However, the brushless DC motor’s armature inductance causes torque ripple turning commutation intervals, which reduces the accuracy of the motor’s position and speed controls. It is suggested to use an automated control to lessen torque ripples in BLDC.
The use of RF technology to detect nuclear radiation is suggested. This system is microcontroller-based and has an integrated nuclear radiation sensor.
An alert and a signal activating additional nearby radiation detectors are activated upon detection. Individual radiation detection devices can send and receive signals since each unit contains a transmitter and a receiver.
Because they integrate two distinct energy sources to form a standby source, hybrid energy systems are dependable alternative energy sources.
Due to variations in energy supplies, distributed production units that produce renewable energy frequently suffer significant changes in the inverter input voltage. For high efficiency and reliability, a one-stage boost inverter with connected inductors is proposed.
In comparison to direct AC-AC converters, the advantages of AC-AC modular multilevel converters include excellent dependability, greater hardware usage, and better control over resonance.
High modularity and voltage quality are also provided by them. Input and output frequency components in the control loop are the primary downside of AC-AC modular multilevel converters. The suggested approach involves a single-phase, AC-AC multilevel converter.
A suggested hybrid resonant and pulse width modulation converter combines a resonant half-bridge and a full-bridge phase-shifted pulse width modulation design.
This system makes sure that switches in the leading leg and switches in the lagging leg operate at zero voltage switching and zero current switching, respectively. For applications such as battery chargers in electric cars, such systems are highly helpful.
The initiative seeks to use TSR to achieve FACTS (Thyristor Switch Reactance). When charging the transmission line, it is done when there is very little or no load at the receiving end. Since there is less current flowing through the transmission line due to the low load, the shunt capacitance is more pronounced.
The voltage at the receiving end grows two times more than the voltage at the transmitting end as a result of this voltage amplification, also known as the Ferranti Effect. Shunt inductors are consequently automatically linked across the transmission line to make up for this.
This project describes how to use thyristor-switched capacitors to produce flexible AC transmission. To address the trailing power factor brought on by the existence of an inductive load, the capacitors are connected in shunt across the load.
By first converting the single-phase AC signal to a DC signal using MOSFET switches and a bridge inverter, and then converting this DC signal to a three-phase AC signal, it is possible to create a three-phase supply from a single-phase supply.
This project outlines a method for achieving induction motor speed control by supplying AC voltage to the motor at three distinct frequencies, with F serving as the fundamental frequency. These frequencies are F, F/2, and F/3.
This project outlines how to supply dc power to the DC motor’s two polarities to get it to rotate in both directions. Thyristors are used to create a dual converter in this case.
The firing angle delay method is used to regulate the voltage provided to the thyristors to control the motor’s speed as well.
When compared to traditional motors, the use of BLDC motors improves several performance characteristics, including efficiency, torque, power density, minimal maintenance, and noise.
This project involves designing a two-leg, inverter-fed BLDC motor drive using just four switches and two current sensors. Less switching loss results from fewer switches and current sensors.

This AC-AC power converter uses a single-phase Z-source. With the inclusion of new benefits like smaller size and continuous input current operation, all the advantages of the conventional single-phase Z-source AC-AC converter are retained. There won’t be a voltage spike on the switch, and the improved single-phase quasi-Z-source AC-AC converter is more efficient than the standard single-phase Z-source AC-AC converters.
For use with AC modules, a low-cost flyback inverter with a sliding mode controller has been proposed. Here, the photovoltaic panel’s maximum power is tracked using a sliding mode controller.
Direct current is changed into alternating current using a flyback inverter. By connecting an LCL filter between the flyback inverter and the load, the overall harmonic distortion of the inverter is decreased.
For high-power applications, a two-stage DC-DC converter with an input series connection is suitable. However, during the step-up-to-step-down transition, the system generates several oscillations.
Consequently, a series buck-half bridge converter that is appropriate for high-power applications is proposed here with input-parallel output.
