What is Dual Power Supply? -Circuit Diagram and its Workings? Many discrete and ICs need bipolar (dual power supply or ± V) supplies. This can be easily accomplished with two…
Fixed Positive Voltage Regulators: The series 7800 regulators provide eight voltage options, rangÂing from 5 to 24 V, as indicated in Table 43.2. These ICs are designed as fixed voltage…
IC Voltage Regulators: IC voltage regulators are versatile and relatively inexpensive and are available with features such as a programmable output, current-voltage boosting, internal short-circuit current limiting, thermal shutdown, and…
Regulated and Unregulated Power Supply: Almost all electronic devices used in electronic circuits need a dc source of power to operate. The source of dc power is used to establish…
What is BJT Beta Rule? Like transfer of primary and secondary winding impedances of a transformer, resistance from one part of a transistor circuit can be referred to another parts.…
Three Phase Rectifiers: Three-Phase Half-Wave Rectifier : Figure 9.11 illustrates a circuit for a 3-phase half-wave rectifier. The three diodes are connected to the three phases of a 3-phase transformer…
Voltage Multipliers - Voltage Doublers, Triplers and Quadruplers Voltage multipliers is a modified capacitor filter circuit that delivers a dc voltage twice or more times of the peak value (amplitude)…
What is Surge Current? - Definition and Workings Before switching on of power supply, the filter capacitor is uncharged [Fig. 9.23]. At the instant the power supply is switched on,…
