Full Wave Rectifier DC Power Supply: Like half-wave rectifiers, full-wave rectifiers require filter circuits to convert the output waveform to direct voltage. Figure 3-13 shows a Full Wave Rectifier DC…
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)…
Half Wave Rectifier Circuit: A basic diode Half Wave Rectifier Circuit is shown in Fig. 3-1(a). An alternating input voltage is applied to a single diode connected in series with…
Energy Conservation in Electrical Drives Articles: Energy Losses in Electrical Drive System: Energy conservation in electrical drive is achieved by reduction of losses in its various parts. Typical Energy Losses…
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…
Power Factor Improvement Methods: There are many drives which operate at a low power factor. Some of Power Factor Improvement Methods are: An induction motor direct on line. ac-dc diode…
Diesel Electric Traction System: Because of high initial cost, electric traction is justified only where there is sufficient volume of traffic. Diesel Electric Traction System is preferable where the traffic…
