the power generated from the renewable sources like solar energy produces is a direct current. This DC power needs to be converted to alternate current power, as most of the appliances use AC power, circuit which convert DC power into AC power at desired output voltage and frequency are called as inverters. Like all power, its needs to be under con...

Rapid depletion of fossil fuel reserves, and concerns over climate change have encouraged power generation from sustainable energy based microgrids. And to address the necessity of three-phase inverters in microgrid systems or sustainable-powered households, an Arduino-based three-phase inverter using MOSFET is designed, which converts DC into three-phase AC power. The designed system generates 223V square signals at each phase from a 12V battery through switching of three stages of power MOSFETs using pulse width modulation (PWM) signals at their gates from an Arduino Uno. Each stage of power MOSFETs consists of six transistors making it eighteen in total, which are used to perform the inversion process separately for each three single-phase connections. The system is programmed using an Arduino Uno to generate PWM signals and to keep 120 degrees phase displacement among each phase. Three step-up transformers are coupled at the outputs of MOSFET stages for amplification. The system generates 386.25V of voltage for the three-phase line delivering 0.58A of current using a 60W incandescent bulb at each phase as a load. The design and simulation of the electronic circuit are done by Proteus, and the programming codes are written using Arduino IDE. The designed system is practically contrasted and verified.
... In applied power engineering fields, the multilevel inverter used in many applications [7][8][9], there are three conventional categories of the multilevel inverters: cascaded H-bridge, neutral point clamped and flying capacitor multilevel inverter [10][11][12]. The multilevel inverter used for Induction heating, Traction systems, Active filtering, Motor drives, High-voltage and Medium-voltage applications [13][14]. The problem is the choice of the switching angles required to control a multi-level inverter with a minimum THD in the system, total harmonic distortion is to the ratio between the RMS value of the signal harmonics (voltage or current) and the RMS value of the fundamental frequency [15]. ...

Induction heating is extensively utilized in various
applications such as melting, metal forming, and heat treating.
To facilitate high-frequency (HF) induction heating, a power
electronic inverter has been specifically designed. This paper
focuses on the development of a series resonant circuit for metal
forming purposes. The series resonant circuit is designed with
three different switching frequency cases. The paper also
presents simulations of the HF inverter design, modeling, and
control circuits. In recent times, there has been a growing
interest in domestic-level induction heating processes due to
their clean, reliable, flexible, and fast operation. To regulate the
output power, a simplified pulse width modulation (PWM)
switching control method was employed. The maximum output
power is achieved when the switching frequency matches the
resonance frequency, as there are no switching losses compared
to frequencies higher or lower than the resonance frequency. In
this case, the power and efficiency achieved are 1014W and
92.4%, respectively. Therefore, it is crucial for the switching
frequency to align with the resonance frequency in order to
obtain optimal results. This study effectively demonstrates the
proposed system's effectiveness for metal treatment induction
heating systems.
This paper describes a controller for Three-Phase Induction Motor. Induction motor is an electromechanical actuator widely used due to its reliability and relatively low maintenance cost. However, the control problem of an induction motor is complex due to nonlinearities, load torque perturbation, and parameter uncertainties. An element included in this study is voltage source control, which is to control the voltage fed from three-phase inverter to Three-Phase Induction Motor. Hysteresis Controller was proposed in this paper to minimize voltage error. Hysteresis controller is seen as an input – output phase lag corrector. The implementation of the designed hysteresis controller is performed in simulation using MATLAB/Simulink. The result proved that the proposed controller design can minimize the line voltage error of the induction motor, preventing the line voltage from being kept low hence avoiding excess current at low speeds.
In this paper, analysis and modelling of a single-phase cascaded full-bridge resonance inverter are considered. The control of proposed inverter by full-wave phase method at high frequency is implemented. In the first step, MATLAB/Simulink environments are used to simulate the model and show obtained results of waveforms. The second step is the experimental validation of simulation results by a realization of the inverter and generated signals. The Root-Mean-Squared voltage of a capacitor waveform between 3 and 7 kHz frequency with simulation and realization are presented, comparatively, for a comparison. The results obtained are satisfactory and show the efficiencies of analysis and the proposed model of the full-bridge resonance inverter.
