Novel Inverter using Field Modulation of AC Machine
Project Area of Specialization Software EngineeringProject SummaryWe are designing a Novel Inverter in which we produce pure sine wave, harmonic free AC output. We will use AC machine structure with windings rewing accorting to our requirement(to produce magnetic filed which will be north and south in opposite so that the filed works properly) for this we will have windings on both direction on a single feromagnetic core winding structure,the purpose of which is that when direction needs to be inverted in order to create north and south pole direction. We will magnitize the filed of AC machine structure by using MOSFET's or IJBT's. In this, we provide DC source to the drain of mosfet and output at the source of that mosfet which is supplied to coil to energize it. The Gate of the mosfet is provided control by a controller(which controls frequency and dutycycle both of the signal) which do switching of coils. The same way all coils are energized or magnetized in sequence using switching which turns in results, the rotating magnetic field is produced. In this way, pure sine wave output is produced with no Harmonics. We will produce output of 100 to 200 watts in prototype.
Project Objectives-
Prototype for High Power Sine Wave Inverter with Low Harmonics.
-
Harmonics Free Pure Sine wave Inverter.
-
To provide a less complex electronic circuit.
-
To provide an inverter with simple control.
-
For reducing cost and improving the performance.
In this project, Firsly we have analayzed the data and background of our project and studied the way to produce the pure sine wave inverter using filed modulation of AC Machine.
We will design the structure of the AC Machine according to the requirement of our project. Then we will implement our project in which first phase, we will analyze for controller module and set it's value of frequency and duty cycle which is then given to an Demultiplexer for controlling of the Mosfet's. These are then provided to transistor to further progress in which signal is given to gate and DC source is applied at the drain. These outputs from source of mofet is provided to coils and megnetization of coils is produced i.e., rotating magnetic field. Then the power is delivered from the coil placed in the magnetic flux of the coils and generated pure sine wave in results.
Benefits of the ProjectThe benefits of the project are
- It less electronic circuit which is easy to control with single DC source and in conventional multilevel inverters, it has complex electronic circuit i.e., more fets with multiple level of DC sources(Cascaded DC voltage).
- It's power ratings will be more than normal.
- Harmonic free pure sine wave inverter. In conventional multilevel inverter, there is stair case sine wave inverter which means it has more harmonics.
We will have a hardware with AC machine structure in which it has rewind coils to produce rotation magnetic field and a coils for induced output from which pure sine wave is produced. Then the electronic circuit in which it has ijbt's and bjt's for the control of the circuit. It also has controller modules for controlling frequency and duty cycle for your signal and has Demultiplexer IC for the contact between controller and mosfet's for the simplicity of the circuit.
