Can you parallel voltage regulators?
To improve efficiency in high-power applications, voltage regulators can be used in parallel to double output current capability—if a means of forcing current sharing is provided. One circuit approach uses sense resistors in series with the load and is applicable to regulators of any type.
What is LDC CT in transformer?
The voltage transformer output et is a reflection of ES, the zone transformer terminal voltage. This compensation for the voltage drop in the line is called ‘line drop compensation’ (‘LDC’). It is usually set as a percent boost in voltage at a certain value of transformer load.
How do I adjust my external voltage regulator?
If the voltage, at which the reading becomes steady, occurs outside these limits, adjust the regulator by turning the adjusting screw 1/4 turn at a time clockwise to raise the voltage or counterclockwise to lower. The adjusting screw can be found on the back of the regulator facing the firewall.
How does a feedback voltage regulator work in a computer?
Feedback voltage regulators operate by comparing the actual output voltage to some fixed reference voltage. Any difference is amplified and used to control the regulation element in such a way as to reduce the voltage error.
How are Zener diode regulators and feedback voltage regulators different?
Zener diode regulators make use of the zener diode’s fixed reverse voltage, which can be quite large. Feedback voltage regulators operate by comparing the actual output voltage to some fixed reference voltage. Any difference is amplified and used to control the regulation element in such a way as to reduce the voltage error.
What kind of voltage regulator does a DC power supply use?
Commercial voltage regulators normally operate on a range of voltages, for example 150–240 V or 90–280 V. Many simple DC power supplies regulate the voltage using either series or shunt regulators, but most apply a voltage reference using a shunt regulator such as a Zener diode, avalanche breakdown diode, or voltage regulator tube.
How is a voltage regulator used in an integrated circuit?
An integrated circuit voltage regulator. A voltage regulator is a system designed to automatically maintain a constant voltage. A voltage regulator may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design,
