This paper presents a Multi-Carrier Pulse Width Modulation control for a Single-phase 27-level Hybrid Multi-Level Inverter for photovoltaic systems. Multi-Carier Pulse Width Modulation technique uses a easy mapping to generate gate signals for the inverter.The Maximum Power Point Tracking is capable of extracting maximum power from PV array connected to each DC linkage voltage stage. The Maximu...
Renewable energy, such as solar energy, is desirable for power generation due to their unlimited existence and environmental friendly nature. Reforming of the electricity sector along with various renewable energy promotion policies has increased the importance of small grid connected photovoltaic (PV) systems utilizing single stage single phase inverters. This paper proposes a single-stage inv...
This paper, proposes an analysis and design of a high efficiency boost-inverter with bidirectional back-up battery storage in fuel cell. When low-voltage unregulated fuel cell (FC) output is conditioned to generate AC power, two stages are required: a boost stage and an inversion one. In this paper, the boost-inverter topology that achieves both boosting and inversion functions in a single-stag...
This paper presents design and analysis of a three phase induction motor drive using IGBT‟s at the inverter power stage with volts hertz control (V/F) in closed loop using dsPIC30F2010 as a controller. It is a 16 bit high-performance digital signal controller (DSC). DSC is a single chip embedded controller that integrates the controller attributes of a microcontroller with the computation and t...
This paper proposes the Modified Switched Inductor Quasi Z Source Inverter (MSL-QZSI) for extracting maximum solar power generation. The Z source inverter uses LC impedance network to couple the main converter circuit to the power source, which provides the boosting of input voltage. It is not possible in traditional voltage-source inverter (VSI) and current-source inverter (CSI). The proposed ...
Model-based Vol/VAR optimization method is widely used to eliminate voltage violations and reduce network losses. However, the parameters of active distribution networks(ADNs) are not onsite identified, so significant errors may be involved in model make model-based infeasible. To cope with this critical issue, we propose a novel two-stage deep reinforcement learning (DRL) improve profile by re...

This brief proposes a fully dynamic discrete-time ${\Delta }{\Sigma }$ ADC using closed-loop two-stage cascoded floating inverter amplifiers (FIA). The proposed FIA uses non-cascoded as the notation="LaTeX">$1^{\mathrm{ st}}$ stage an...
This paper focuses on developing a low cost and a low harmonic traditional three level inverter (H-Bridge) using pulse pattern. Multilevel inverter as compared to traditional three level inverters have advantages like low harmonic contents and low electromagnetic interference (EMI) outputs and can operate on several voltage levels. The drawbacks includes: The requirement of isolated power suppl...
this paper presents the new topology of three phase on line uninterruptible power supply (ups) by employing t-source inverter (tsi) with maximum constant boost pulse width modulation (pwm) control and the results are compared with the conventional uninterruptible power supply (ups). the conventional ups consists of voltage source inverter (vsi) with step up transformer or dc-dc booster which de...
