How may commutator ripple be reduced

Ripple is wasted power, and has many undesirable effects in a DC circuit: it heats components, causes noise and distortion, and may cause digital circuits to operate improperly. Ripple may be reduced by an electronic filter, and eliminated by a voltage regulator. Meer weergeven Ripple (specifically ripple voltage) in electronics is the residual periodic variation of the DC voltage within a power supply which has been derived from an alternating current (AC) source. This ripple is due to incomplete … Meer weergeven Most power supplies are now switched mode designs. The filtering requirements for such power supplies are much easier to meet … Meer weergeven Ripple current is a periodic non-sinusoidal waveform derived from an AC power source characterized by high amplitude narrow bandwidth pulses. The pulses coincide with peak or near peak amplitude of an accompanying sinusoidal voltage waveform. Meer weergeven • Rectifier, a non-linear device that is a principal source of ripple • Dynamo, the instrument of DC power generation, whose output contains a large ripple component • Ringing (signal), the natural response time domain analog of frequency domain ripple Meer weergeven A non-ideal DC voltage waveform can be viewed as a composite of a constant DC component (offset) with an alternating (AC) voltage—the ripple voltage—overlaid. The ripple … Meer weergeven A capacitor input filter (in which the first component is a shunt capacitor) and choke input filter (which has a series choke as the first component) can both reduce ripple, but have opposing effects on voltage and current, and the choice between … Meer weergeven Ripple in the context of the frequency domain refers to the periodic variation in insertion loss with frequency of a filter or some other Meer weergeven WebGenerators use a modified slip ring arrangement, known as a commutator, to change the AC produced in the generator loop into a DC voltage. ... This variation of DC voltage is …

Chapter.3 Design of Commutator and Brushes and problems

WebSince there are now four commutator segments in the commutator and only two brushes, the voltage cannot fall any lower than at point A.
