Power Inverters have a high range of applications not only in domestic appliances but also in industries for performing variety of operations regarding switching and conversion of electrical energy. The purpose of this research paper is to analyze a three phase inverter using PWM topology to obtain a smooth and pure sinusoidal wave form of good quality which ensures better operation for sensiti...

Based on the combination of a three-phase diode bridge and a dc/dc boost converter, a new three-phase threeswitch three-level pulsewidth modulated (PWM) rectifier system is developed. It can be characterized by sinusoidal mains current consumption, controlled output voltage, and low-blocking voltage stress on the power transistors. The application could be, e.g., for feeding the dc link of a te...

This paper presents a micro controller based control of multilevel inverter for single phase Induction motor. IGBT is used as power element. Pulse width modulation techniques (PWM), introduced three decades ago, are the most used methods to control the voltage and frequency supplied to electrical AC machines. This work proposes a new switching scheme for the cascaded H-Bridge multilevel inverte...

In recent years, light-emitting diode (LED) technology emerged as a prime candidate for the future illumination light source, due to high energy efficiency and long life time. In addition, LEDs offer a superior flexibility in terms of colors and shapes, which leads to a potentially infinite variety of available light patterns. In order to create these patterns via easy user interaction, we need...

this paper proposes a flexible power electronic transformer (fpet) for the application in the micro-grids. the low frequency transformer is usually used at the point of common coupling (pcc) to connect the low voltage grid and utility network to each other. the conventional 50hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. in this pap...

Space Vector Pulse Width Modulation is popular for variable frequency drives. The method has several advantages over carried based PWM and is computation intensive. The implementation of SVPWM for multilevel inverter requires special attention and at the same time consumes considerable resources. Due to faster processing power and reduced over all computational burden, FPGAs are being investiga...

Medium voltage hybrid bridge multilevel converter (MMC) usually has a lower number of links. Therefore, the traditional Nearest Level Modulation (NLM) method problems low equivalent switching frequency and poor output quality. And Carrier Phase-shifted Pulse Width (CPS-PWM) modulation such as difficulty in control, redundant configuration, large amount calculation. In response to above problems...
