  • Voltage Multiplier Technique

    2404 Words  | 10 Pages

    This paper introduces the use of the voltage multiplier technique and passive absorption circuit applied to the non-isolated dc-dc converter in order to obtain high efficiency and high voltage gain. A passive absorption circuit is inserted in the interleaved flyback converter to transfer the leakage energy to load. The operation principle of the circuit is explained. This paper also deals with MPPT controlled high step up dc-dc converter. The switching element used in the flyback converter is MOSFETs

  • Essay On Voltage Multiplier

    627 Words  | 3 Pages

    DESCRIPTION VOLTAGE MULTIPLIER MODULE A voltage multiplier is an electrical circuit that converts electrical power from a lower voltage to a higher voltage, typically using a network of capacitors and diodes. In the voltage multiplier module of the proposed converter, the turns ratio of coupled inductors can be designed to extend voltage gain, and a voltage-lift capacitor offers an extra voltage conversion ratio. A conventional boost converter and two coupled inductors are located in the voltage multiplier

    Multispeed vs reduced voltage control starter Mohammad Amin Hilal 60061058 CM 2181-2 Miss. Smith March 10, 2014 Table content: 1.0 Introduction Centrifugal pump is a type of pump which increases the pressure of fluid and solid atom mixture over centrifugal force. This is the pump used for slurry pumping. In addition, the pump is also capable of converting electrical energy into slurry potential and kinetic energy. Furthermore, slurry pumps are generally used to carrying

  • Factors of Voltage and Current

    between work piece and electrode the voltage is applied. Alternatively the time during which no voltage is applied is the pulse off time. A greater value of On time is selected to obtain a long duration of electric discharge to increase the material removal rate but also leads to poor surface finish. During the pulse off time re-ionization of dielectric occurs and it is also essential to avoid any short circuit leading to wire breakages. 2.1.2 Peak current and gap voltage In WEDM, the most important machining

  • Essay On Voltage Stability

    603 Words  | 3 Pages

    Voltage stability is defined as the ability of a system to restore steady voltages at all buses in the power system after being exposed by any disturbance from a given initial operating conditions. Voltage stability purely depends on the capability to maintain equilibrium between load supply and load demand from the consumer end. When there will be any progressive fall or rise of voltages of some buses that can cause instability. Power system stability is expressed by the capability of a power system

    2302 Words  | 10 Pages

    turn causes voltage harmonics. Current harmonic causes increased power system losses, excessive heating in rotating machinery, interference with nearby communication circuits and control circuits, etc. It has become a vital importance to maintain the sinusoidal nature of voltage and currents in the power system. Various international agencies like IEEE and IEC have issued standards, which put limits on various current and voltage harmonics. The limits for various current and voltage harmonics specified

  • Powering A World; Kirchhoff's Voltage Law

    1093 Words  | 5 Pages

    if there is enough electricity to power each and every light. Throughout this paper, we examine Kirchhoff’s Voltage Law the sum of the electrical potential differences around any closed network is zero [1]. Represented by the equation ΣV=0, which means v1+ v2+ v3+…+ vn=0 [2]. A way at looking at this equation in words is by the sum of the voltage rises in the loop will equal the sum of voltage drops in the loop [2]. By applying this principle electrical engineers can use this to determine if there

  • Factors that Affect the Amount of Voltage in a Wire

    413 Words  | 2 Pages

    Factors that Affect the Amount of Voltage in a Wire We are going to find out what factors affect the ammount of voltage in a wire. Theory As soon as we turn on the power pack electrons are being forced through the wire. If we increase the voltage on the power pack this generates more heat in the wires but this can not be controlled. If the resistance wire is long it will take longer for the electrons to pass through. Just like if you were trying to run round
