Detailed Solution
Download Solution PDFIn a Zener regulator, the change in load current produces, change in Zener current
Explanation:
Voltage regulator: It is used to regulate the voltage level. It generates a fixed output voltage that remains constant for any changes in load conditions or input voltage, i.e. it regulates or maintains a constant dc output voltage in spite of the fluctuations in ac input voltage or load current.
Zener diode: Zener diode is a device widely used in voltage regulator circuits.
- It is PN junction (silicon PN junction) diode and has a low specified reverse voltage which takes advantage of any reverse voltage applied to it.
- Unlike a normal diode (Schottky diode, varactor diode, tunnel diode) that blocks any flow of current through itself when reverse biased.
- From the I-V characteristics curve above voltage across the diode in the breakdown, the region is almost constant.
- In the breakdown region, it can be used as a voltage regulator applications.
