Half Wave Rectifier with Capacitor Filter: Half Wave Rectifier with Capacitor Filter - When a sinusoidal alternating voltage is rectified, the resultant waveform is a series of positive (or negative)…
Diode Approximations: Diode Approximations - As we know already that, a diode is essentially a one-way device, offering a low resistance when forward biased, and a high resistance when biased…
Forward and Reverse Bias Characteristics of Diode: Figures 2-4 and 2-5 show typical Forward and Reverse Bias Characteristics of Diode for low-current silicon and germanium diodes. From the silicon diode…
Traction Drives Articles: Electric Traction Services: Electric Traction Services can be broadly classified as: Electric Trains. Electric buses, trams (or tramways) and trolleys. Battery driven and solar powered vehicles. Electric…
Induction Motor Drives Articles: Three Phase Induction Motors: Three Phase Induction Motors are of two types: squirrel-case and wound-rotor. In squirrel-cage, the rotor consists of longitudinal conductor-bars shorted by circular…
Interlocking Components in Electrical Drives: Sensing of signals required for speed and current control loops. Sequencing and interlocking operations are explained in the previous section, whereas this section discusses components…
Use of Efficient Semiconductor Converters: Prior to development of Use of Efficient Semiconductor Converters, inefficient power modulators were employed in several applications. While replacement of these power modulators by the…
Semiconductor Converter Controlled Drives: These are now widely used both in ac and dc tractions involving dc and ac motors, and the conventional drives have all become outdated, and will…
