Virtual prototyping is a method used for the prediction of electrical machine parameters during the design stage, thus reducing the development time and cost for new machines. Based on the simulated results of the virtual prototype, the design is fine-tuned and finalized. In synchronous generators, the design of a third harmonic excitation (THE) winding is done based on the third harmonic flux generated...
Indirect vector control or Indirect Field Oriented Control (IFOC) is known to produce high performance in induction Motor (IM) drives by decoupling rotor flux and torque producing current components of stator current. The most commonly used controller for the vector control of ac motor is Proportional- Integral (P-I) controller. However, the P-I controller has some disadvantages such as high starting...
The synchronous generators for standalone industrial applications with full pitched windings have high harmonic content across line and neutral due to triplen harmonics and single phase loads connected across such machines are adversely affected. To circumvent this problem, conventionally the main winding is wound for 2/3rd pitch which introduces complexity in winding, reduced KVA and hence results...
As demand for renewable energy generation increases, the demand for power inverters with voltage buck-boost capability is also expected to rise. This is because the output of renewable energy sources such as solar panel, wind turbines etc are not constant due to varying climatic as well as geographic conditions. So in order to obtain an ac supply with adjustable voltage and frequency, a multi level...
