Servo Type Voltage Regulator Working Principle: The main features of a servo type voltage regulator using an amplidyne is depicted in Fig. 19.8. The servo type voltage regulator system comprises…
Speed Control of Single Phase Induction Motor using Triac (Fan Regulator): The conventional speed regulator for a fan uses a resistance regulator. The regulator resistance is in series with the…
Voltage Control Interview Questions and Answers: 1. Why is it necessary to keep the receiving-end voltage constant within specified limits ? Ans. For satisfactory operation of equipment/machinery supplied by the…
Switch Mode Power Supply (SMPS) or Switching Regulators: Switch Mode Power Supply (SMPS) - The regulated power supplies described earlier were basically linear voltage regulators. A linear voltage regulator possesses…
Adjustable Voltage Regulators: Sometimes variable voltage is required and under such a situation adjustable voltage regulators is used. A number of IC regulators, like LM317, LM338, and LM350, are adjustable…
Fixed Negative Voltage Regulator: As we have seen many times previously, positive and negative regulated power supply voltages are often required. In response, many manufacturers have developed negative three-terminal regulators.…
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…
Three Terminal IC Voltage Regulators - Block Diagram: The latest generation of IC voltage regulators has devices with only three pins: one for the unregulated input voltage, one for the…
