Three fundamental sine-wave inverter topologies are analyzed: two-leg (one-phase, two-wire); three-leg (three-phase, three-wire); and four-leg (three-phase, four-wire). The topologies are “full-bridge” voltage-source inverters with LC filters suitable for producing sinusoidal output voltages. The switching states and corresponding output voltage vectors produced by each inverter are identified ...

This paper presents a compact analog neuron cell incorporating an array of charge-coupled synapses connected via a common output terminal. The novel silicon synapse is based on a two stage charge-coupled device where the weighting functionality can be integrated into the first stage. A presynaptic spike to the second gate allows the charge under the first gate to drift onto the floating diffusi...

Due to the nonlinear nature of photovoltaic (PV) cells and dependence maximum achievable power on environmental conditions, a robust controller is essential warrant point tracking (MPPT) by managing nonlinearities system making it against varying conditions. Most methods used obtain MPPT have some disadvantages; one them oscillation around operating point. In this paper, minimize these problems...

In order to supply power from a solar panel or photo voltaic system at a low voltage to a grid at high voltage, a power electronic converter which is capable of voltage boosting and inversion is required. Newly introduced Switched Boost Inverter is capable of achieving both these objectives by a single stage. This paper presents a PWM control strategy based switched Boost Inverter (SBI) for DC ...

The power electronics device which converts DC power to AC power at required output voltage and frequency level is known as inverter. Multilevel inverter as compared to single level inverters has advantages like minimum harmonic distortion, reduced Electromagnetic interference (EMI)/Radio frequency interference (RFI) generation and can operate on several voltage levels. A multi-stage inverter i...

Multilevel inverter technology has emerged recently as a very important alternative in the area of high-power medium-voltage energy control. This paper presents modeling and simulation of a single phase simplified eleven-level inverter (SELl). Multilevel inverter offers high power capability. Its performance is highly superior to that of conventional two-level inverter due to reduced harmonic d...

In this paper, class DE inverter with second order constant K band-pass filter is proposed. In the proposed inverter, the band-pass filter is used instead of the resonant filter in class DE inverter presented at the previous papers. By using band-pass filter, two important results can be gotten. One is the sensitivity of the output voltage to the operating frequency is suppressed by using band-...

This Paper presents the design and implementation of a single phase inverter using IGBT as switch and the study of the output responses. The inverter consists of two parts: the control circuit and the power circuit. The control circuit is responsible for generating the gate pulses to trigger the IGBTs. The pulse width modulation technique has been used to obtain pulse width modulated (PWM) puls...

A single phase cascaded inverter consisting of two full bridges creates a five level AC output voltage. Due to switch combination redundancies, there are certain degrees of freedom to generate the five level AC output voltage. A single phase Pulse Width Modulation (PWM) Multil Level Inverter (MLI) produces AC output voltage of desired magnitude and frequency. The purpose of voltage controller f...
