Diode Applications Articles: 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…
Power Supply Decoupling: Power Supply Decoupling - High-power amplifiers require high supply current levels, so unregulated power supplies are often employed to avoid the power wasted in a series regulator.…
Output Current Limiting: Because the output transistors can be destroyed by excessive current flow, output current limiting circuits are often included in a power amplifier. Figure 18-27 shows the typical…
Step Down Converter: A step-down switching regulator, or Step Down Converter (also termed a buck converter), produces a dc output voltage lower than its input voltage. The basic circuit arrangement…
Short Circuit Protection Circuit: Power supplies used in laboratories are subject to overloads and short circuits. Short Circuit Protection Circuit by means of current limiting circuits is necessary in such…
Integrated Circuits Fabrication Process: IC Types - An Integrated Circuits Fabrication Process consists of several interconnected transistors, resistors, etc., all contained in one small package with external connecting terminals. The…
Self Controlled Synchronous Motor Drive: A Self Controlled Synchronous Motor Drive employing a load commutated thyristor inverter is shown in Fig. 7.10. In large power drives wound field synchronous motor…
Rotor Resistance Control of Induction Motor: Speed-torque curves for Rotor Resistance Control of Induction Motor are given in Fig. 6.50. While maximum torque is independent of rotor resistance, speed at…
