Regulated and Switching Power Supplies Interview Questions and Answers: 1. What is a regulated power supply? Ans. A regulated power supply is an electronic circuit designed to provide constant dc voltage…
Switching Characteristics of Power MOSFET: Power MOSFET is an enhancement mode device modified to handle much large currents and voltages than a conventional MOSFET. Prior to the invention of the…
What is Switching Circuit? In practice, we often need making (switching on) and breaking (switching off) of an electrical circuit. It is also desirable and sometimes essential that the switching…
Applications of FETs (Field Effect Transistors): Applications of FETs - FET has a very high input impedance (100 MΩ in case of JFETs and 104 to 109 MΩ in case of…
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…
Phototransistor Construction and Working Principle: The sensitivity of a photo diode can be increased by as much as 100 times by adding a junction, resulting in an NPN device. A…
IC Controller for Switching Regulators: The functional block diagram of a MC34063 integrated circuit controller is shown in Fig. 17-38. This IC is designed to be used as a variable…
Switching Regulator Operation: A Switching Regulator Operation can be thought of as similar to a linear regulator, but with the series-pass transistor operating as a switch that is either off,…
