“…In the pursuit of enhancing the utilization rate of the DC bus voltage, researchers in power electronics have focused on various design and implementation approaches for single-phase inverters. Some recent studies have employed FPGA (field-programmable gate array) [9], Atmega (such as Atme-ga16, AT89S52) microcontrollers [10], DSP (digital signal processor) (such as TMS320F241) [11], and PIC (peripheral interface controller) microcontrollers (such as PIC30F4013, PCI16F877A) [12] [13]. These studies have explored different microcontroller platforms and programmable devices to develop inverters.…”

A large amount of switching loss occurs in the inverter. From this point of view, an inverter design should be optimized for which size and cost will be minimum along with increasing efficiency. The main aim of this paper is the analysis and development of single-phase and three-phase inverter to design with MOSFET and IGBT as power elements by sinusoidal pulse width modulation (SPWM) technique using MATLAB Simulink software and compare their difference with the practical inverter. This work proposes different multilevel stages for the cascaded H-Bridge inverter to enhance the output voltages. Then compare their performance, harmonic distortion, and frequency spectrum. The hardware of an inverter circuit has been developed using the SG3524 microcontroller. The main goal of this design is to generate a sine wave with fewer harmonics, while keeping the cost and complexity of the circuit low. The designed inverter has undergone testing with different AC loads and is primarily intended for low-power applications, as lamps, fans, and chargers. This design aims to provide a reliable and efficient inverter solution for these specific applications.

This work develops a 2KVA inverter with timing capability for load supply.The development of timing-capable inverter draws from a DC input which could be a solar/deep cycle battery source. Public power supply could be used to charge the battery. The inverter used the pulse width modulation (PWM) approach and used the SG3524N IC as the Pulse Width Modulator (PWM).Dual channel MOSFETs are supplied current of 10ms duration every 20ms and are used to alternately supply the primary windings of a step up transformer thereby producing an AC in the secondary of the transformer. A step-down transformer, bridge rectifier, and the pulse width modulator were used to provide voltage regulation of the output supply to the load. A keypad, a GDM1602A LCD screen and a PIC16F84A microcontroller were employed in the timing control of the voltage from the output of the inverter. Relays were employed in switching the voltage to the output based on the timing algorithm from the microcontroller. A prototype 2kVA inverter with timing was designed and implemented with a satisfactory output and suitable timing control.

Abstract-Pulse Width Modulation (PWM) is a common technique used in many different applications.This technique is the heart of the inverter system. This paper reported a modified strategy in asynchronous unipolar sinusoidal PWM (SPWM) switching scheme based on ACEX1K50TC144-3 Altera Field Programmable Gate Array (FPGA). The carrier frequency was designed for 20 kHz and the fundamental frequency was designed to adjust 1 to 100 Hz, with step increase in 1 Hz. A new SPWM signal generation strategy is proposed and compared to traditional SPWM generation technique. The design entry is conducted by Max+plus II version 10.2 through schematic and VHDL programming. The verification in level simulation and hardware realization has been done. As the result, the proposed modified SPWM signal generation strategy works properly and can reduces the usage of logic cell (LC) until 63.75%.Index Terms-Drive, FPGA, inverter, PWM. I. INTRODUCTIONPulse Width Modulation (PWM) has become the facto in industrial standard. PWM is a common technique used in many different applications. This technique is the heart of the inverter system control signal. Up to now, many types of modulating modes have been brought forward in motion control and power conversion, such as sinusoidal PWM, space vector PWM, current tracking PWM, harmonic elimination PWM and so on [1,2,3,4]. These methods have some advantages and disadvantages, but the most widely techniques used are the sinusoidal PWM and the space vector PWM.Most of these PWM techniques are realized by software and motion control Application-Specific Integrated Circuit (ASIC). There are also some analog circuits in ASIC. ASIC is a very good approach to generate PWM signals; its' performance and cost have challengeable advantages. However, their design is limited by semiconductor manufacturers and the users cannot change their functions. The most famous SPWM ASICs include Siemens SLE4520, Marconi MA818, and Phillips HEF4752V. They are successful as the total digital control IC, and they can be used independently as well as incorporated into a microprocessor-based system [5]. But the switching frequency can be up to 1000Hz, so it is only suitable for low speed power devices as BJT and GTO, not for IGBT or MOSFET.Many efforts have been conducted to make strategies of PWM generation in analog or digital domain. The digital PWM generation techniques have successfully eliminated the component drift and tolerance problems associated with earlier analogue implementation. The digital designs based on FPGA have been used successfully in many different electric system applications such as in power converter PWM inverter. Speed performance is considered as an appropriate solution in order to boost the performance of controllers for industrial control systems as an effort to reduce the gap between the analog and digital world [6,7]. Designing a PWM inverter drive using FPGA has several advantages, such as quick, modifiable, and suitable for prototyping.The PWM technique has been the subject of intensive resea...
