  • Technical Article: Magnetic Induction Voltage Regulator Operation
    Another means of changing output voltage in a transformer is to alter the physical orientation of the primary and secondary relative to each other. In a transformer the primary windings produce a magnetic flux field that induces current to flow in the secondary windings. Physically repositioning
  • Technical Article: Tap Changing Voltage Regulator Operation
    Simply said, when a transformer has an equal number of winding turns on the primary (input) and secondary (output), the input and output voltage should be equal. By adding or subtracting the number of turns on the secondary, the output voltage can be changed - up or down, respectively. Rather than
  • Technical Article: Electronic Tap Switching Voltage Regulator
    , the electronic voltage regulator will have taps on the secondary side of the transformer controlled (on or off) by semiconductor switches (like the silicon controlled rectifier - SCR). Within the classification of electronic tap switching voltage regulator there are two distinct types: the full power
  • Ultra Low Voltage Imaging with Hitachi's S-4800 FE-SEM
    Field emission SEMs are used primarily for their performance at low voltage. The brightness of the source provides the much needed signal for high-resolution secondary electron imaging. Microscopists often work in this region to see such benefits as fine surface detail and minimal specimen charging
  • Active and Passive Isolators
    for the transmission of direct current (DC) signals. The DC measuring signal is therefore first converted into an alternating voltage using an electronic chopper. This AC voltage is transmitted to the secondary circuit by a transformer, where it is rectified in sync with the chopper frequency (see Fig. 3
  • Dynamic sensing with LVDTs
    to the primary. Centering the movable core between the primary and secondary windings produces an identical magnetic flux on both sides. Equal flux induces equal voltages on the two secondary windings. However, as the core moves, the ratio between the two voltages changes. The change in voltage turns
  • Transformer Theory
    . The energy applied to the primary must be in the form of a changing voltage which creates a constantly changing current in the primary, since only a changing magnetic field will produce a current in the secondary.
  • . This magnetic field induces an alternating (AC) voltage in the secondary coils that are in proximity to the core. As with any transformer, the voltage of the induced signal in the secondary coil is linearly related to the number of coils. The basic transformer relation is: (1)
  • T1/E1/J1 Asymmetrical Protection (.pdf)
    on voltage for the A2106 is 170 volts from tip to ground and ring to ground. This is compliant with TIA-968 (formerly known as FCC Part 68) section titled "Intentional paths to ground". The secondary side of the transformer has the P0080SA MC SIDACtor (R) device that will limit differential voltages
  • The Terms "Neutral" and "Ground" Seem to be Used Interchangeably. Do They Mean the Same?
    to supply power to individual residences. The single-phase three-wire configuration consists of a single-phase transformer with two 120 volt secondary windings. The center connection between the two secondary windings is called the neutral. The neutral connection allows the three-phase WYE
