Introduction
A single phase inverter circuit is supplied from a 250V DC source which also supplies and 8 Ohm resister in series with a 0.02H inductor. The inverter is configured to operate in quasi-square mode at 50Hz with a duty cycle of 0.6. Objectives

The main objectives of this report is to build and simulate a single phase inverter circuit with a a load consisting of a resistor and an inductor using the Pspice student software and using this software to obtain the load current and load voltage waveforms and also plot the RMS (Root Mean Squared) load current, the RMS diode current (D9), the RMS thyristor current (D14) and the mean power in the load based on the I2R calculation.

Figure 1: Single phase inverter schematic

Analysis
The waveform for the load voltage is 197V but shows a distorted square wave due to the load being inductive. The peak of the waveform slopes because the inductor is de-energizing and when the voltage passes 0V line and it takes 2ns to reach the zero line because the inductor takes a short time to become energized. The load current starts at 25A and because the load is inductive the current lags the voltage by 90 degrees. According to the Pspice program the RMS current through the diode (D14) is 0A which doesn’t seem correct. The RMS thyristor current starts at 25A and drops to 10A after 100ns and continues to operate at this current. The RMS load current begins at 25A and drops to 16A, this current is also DC. The power dissipated is 4.85kW and the beginning but then drops and varies between 2.1kW and 2.15kW after 100ns Results

INTRODUCTION
1.1 Introduction
Inverters are used to produce constant or variable frequency AC output
from a DC source. These inverters can be used for AC applicatio n like
driving an induction motor. Such type of inverters in present world are
used largely in renewable energy systems to convert DC to AC, example is
a PV system where...

Single-Phase Motors
Introduction
As the name suggests, these motors are used on single-phase supply. Singlephase motors are the most familiar of all electric motors because they are
extensively used in home appliances, shops, offices etc. It is true that singlephase motors are less efficient substitute for 3-phase motors but 3-phase power
is normally not available except in large commercial...

POWE INVERTER FOR HOME USE AND SIMPLIFIED CIRCUIT DIAGRAMME
POWER INVERTERS
Power inverters are simply DC (direct current) to AC (alternating current) converters - they convert DC energy stored in a battery, to the electric current (AC) that your appliances require. An inverter taps current from the public supply when that is on (or, alternatively, from a power generator), stores that power in its battery bank as DC and...

...Abstract:
In this paper, a new topology is proposed for three-phase to single-phase matrix converters, where more voltage levels are produced in the output in comparison with the conventional topologies. In addition, a new control method based on minimum error between the generated and the desired output voltages is proposed for three-phase to single-phase matrix converters. In the proposed control method,...

...Thus a solar inverter is used to convert the energy from the Sun to Electrical energy it is hence known as Solar Inverter.
A Solar Inverter converts the variable direct current (DC) output of a photovoltaic(PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical component in a photovoltaic system, allowing the use of ordinary...

...For a play to be considered a revenge tragedy, revenge has to be a prevalent theme throughout. Revenge needs to be intertwined in character interactions, and have a strong hold on the driving force of the plot. The desires of Hamlet, Laertes, and young Fortinbras each exhibit how the plot of Hamlet, by William Shakespeare revolves entirely around theories of revenge.
The theme of revenge starts off very early in the play, when Hamlet speaks with the ghost of his deceased father. When the...

The Cross Field Theory of SinglePhase Induction Motor
The cross field theory of singlephase induction motors looks at the induction motor from a totally different point of view. This theory is connected with the voltages & currents that the stationary stator magnetic field can induce in the bars of the rotor when the rotor is moving.
Consider a singlephase induction motor with a rotor which has been...
