Power electornic lab2 - Essay ExampleTransformers generally consist of 2 windings primary and secondary as shown in the diagram below. If the primary windings consist of more turns than the secondary windings, the transformer is a step down transformer as the one shown below. Transformers with greater amounts of secondary windings than primary windings are known as step up transformers. Step down transformers are more common in industries where they are machine-accessible from the business leader grid to the householdsTransformers are also divided into two high frequence and low frequency transformers. The low frequency transformers work best at 50/60 Hz art object the high frequency transformers work best at 100 kHz. Each set of the devices posses advantages everywhere the other in some situations. The low frequency transformer has low eddy electric current lose, lower array capacitances and comparatively low antenna losses. On the other hand, the high frequency transformer has a lower magnetizing current meaning that it needs less inductance so that fewer turns fiord a larger venture of copper wire. This minimizes copper losses. Deciding the best transformer relies on the costs and efficiency. Overall, the high frequency transformer is efficient while the low frequency transformer is less costly.Table 1.1 illustrates the difference between type and practical transformer. From the outset, it is conclusive that the ideal transformer doesnt account for the losses in the circuit while the practical transformer does.The experiment included a single design calculation to determine the resistor needed for the power resistor. In the calculation, it was found that the mensurate of the power resistor must exceed 30. This meant that the best resistor for the experiment was the 33 power resistor.The first lab question was about the meaning of load normal. From research it was determined that voltage regulation is
