  • Don't let regen rock your world
    it down and causing a loss of control over the mechanism. To prevent this, a regenerative (or regen) circuit shunts some or most of this excess energy into an external resistor. Application notes for commercial amplifiers typically neglect the effect of friction. Thus they assume more energy
  • Souped-up servoamps
    . During regenerative braking, the motor converts kinetic rotational energy into electrical energy and returns this energy to the dc supply via the amplifier power bridge. The motor kinetic energy is absorbed by a power supply reservoir capacitor or by a special energy dumper connected in parallel
  • Subtleties of servoamps
    if the over-voltage protection circuit activates. For example, the amplifier's over-voltage protection circuit triggers as voltage rises during regenerative braking. The amplifier shuts down, halting deceleration and leaving the motor to coast uncontrolled. With the amplifier shutdown
  • Fundamental Characteristics of Thyristors (.pdf)
    between the two transistors trigger the occurrence of regenerative action when a proper gate signal is applied to the base of the NPN transistor. Normal leakage current is so low that the combined hFE of the specially coupled two-transistor feedback amplifier is less than unity, thus keeping
  • Spectral Broadening and Temporal Compression of Ultrashort Pulses in a Gas Cell
    are used to route the beam to a two. inch 2000 mm radius of curvature concave mirror. The concave mirror focuses the. pulse in the center of the gas cell filled with one atmosphere of argon. regenerative amplifier seeded with the Spectra-Physics. Tsunami oscillator. The Spitfire is capable of more than

    and amplifier to the. power supply, especially in system with little or no friction. A shunt regulator is used in. this case to dissipate this "regenerative" energy and avoid an over voltage fault. If a. voltage fault were to occur on the amplifier, it would shut off and the load would be left. spinning
