Essays on Sinusoidal

Liver is the largest ‘gland’ of the digestive system. It is located right under the dome of the diaphragm, coated by the capsule. It is distinguished the liver’s convex upper surface adjacent to the diaphragm, and a lower, downwardly facing and in contact with the back and abdominal organs. On the part of the upper surface of the liver it can be seen its right and left lobes, the boundary of which is the crescent liver ligament. To the lower surface of the right lobe there is a gallbladder, close to the deep groove of the liver there ...

Synopsis

In this experiment, AC circuits, capacitors, and inductors are reviewed. Circuit analysis to cover sinusoidal signals is done. The experiment is drawn from lecture 5 and six learned on series and parallel configuration of RLC circuits, that is, Resistor –capacitor, RC; Resistor-inductor, RL; series Resistor-Inductor-Capacitor; RLC; and parallel RLC circuits.

Introduction

The three basic passive components, resistor, inductor, and capacitor have varied phase relationships when connected in a sinusoidal AC circuit. Analysis of a series RCL circuit is similar to dual series RL and RC circuit. Series RCL circuits are categorized as second order circuit because they have two energy ...

PURPOSE

This experiment is about the isolation of the three harmonics that is included in a non-sinusoidal waveform. The non-sinusoidal waveform here is a square wave, and the harmonics being isolated are the fundamental, third, and fifth harmonics. The experimental amplitudes and frequencies will be compared to the theoretical computations.

Abstract

Permanent magnet synchronous motors (PMSM) are a type of motors that have permanent magnets mounted on the rotors instead of the rotor windings. This particular design gives the motor a few advantages over ordinary induction synchronous motors. The magnets attached to the rotor do not require excitation, which reduces the power consumption in PMSM. This gives the motor high operational efficiency and reduces the motor active diameter. PMSM are therefore associated with applications that require high torque but have limited operation space. The permanent magnets suffer from flux leakage and are therefore aligned in a pattern that minimizes flux ...

Introduction

Numerous electrical applications require an inverter, which converts Direct Current (DC) to Alternating Current (AC) power. Some of these applications require the stepping down of voltage levels when realizing this conversion, which signifies that the input DC power is greater than the AC power. Conversely, certain applications require the opposite: to step up voltage when performing the power conversion, which means that the input DC power is lower than the AC power. These requirements can be met through the use of Voltage Source Inverters and Current Source Inverters, respectively. However, some particular applications require to step down voltage for ...

Introduction

Signals that are periodic can be represented in time and frequency. In any analysis there are major signals which are used; these signals include sine, triangle and square. Additional signals can be derived from the three main signals. There is an important component in signal technology, the low pass filter. This is an electronic gadget that used in the filtering process of the signals. The filtering process is undertaken by allowing all the frequency components that come below the cut-off frequency to go through the circuit while all other frequencies that are above cut-off frequency will be bypassed. Noise ...
