  • All the designs that become are not for arming them and that works in their beginning, but to only have an approximated idea of the components to use. To remember here one of the laws of Murphy: " If you make something and works, it is that it has omitted something by stop ".The calculations have so much the heuristic form (test and error) like algoritmic (equations)and, therefore, they will be only contingent; that is to say, that one must correct them until reaching the finished result.

  • Electricity is an invisible force that is used to transfer energy into heat, light, intelligence, or motion. Electricity is explained in terms of electrical charge, potential differ- ence (or voltage), electrical charge flow (or current), and resistance to current flow. Figure 1-1 graphically illus- trates electron flow through a conductor by comparing it with water flow through a pipe. The normal unit of current measurement is the ampere, whereas the normal unit of voltage measurement is the volt. The unit of opposition to current flow, or resistance, is the ohm...

  • Power flow solutions are needed in both for planning and operation studies. Power flow studies for three phases balanced power system can be carried out using very efficient methods. Power flow analysis for certain type of power system network can be carried on by using several software that already been develop without manual calculation on this time. One of the software is MATLAB with its toolbox: Power System Analysis Toolbox. This software also uses numerical methods to do power flow analysis like Newton-Raphson and its modified form, Fast Decoupled Method.

  • This chapter discusses sinusoidal steady state power calculations. Numerical integration is used to obtain the rms value, average power and quadrature power. Three-phase circuits are analyzed by converting the circuits into the frequency domain and by using the Kirchoff voltage and current laws. The unknown voltages and currents are solved using matrix techniques. Given a network function or transfer function, MATLAB has functions that can be used to (i) obtain the poles and zeros, (ii) perform partial fraction expansion, and (iii) evaluate the transfer function at specific frequencies.

  • This short book provides basic information about bioinstrumentation and electric circuit theory. Many biomedical instruments use a transducer or sensor to convert a signal created by the body into an electric signal. Our goal here is to develop expertise in electric circuit theory applied to bioinstrumentation. We begin with a description of variables used in circuit theory, charge, current, voltage, power and energy. Next, Kirchhoff ’s current and voltage laws are introduced, followed by resistance, simplifications of resistive circuits and voltage and current calculations.

  • A control system is a collection of components working together under the direction of some machine intelligence. In most cases, electronic circuits provide the intelligence, and electromechanical components such as sensors and motors provide the interface to the physical world. A good example is the modern automobile. Various sensors supply the on-board computer with information about the engine’s condition. The computer then calculates the precise amount of fuel to be injected into the engine and adjusts the ignition timing. T...
