6 FAQs about [Working principle of medium voltage variable frequency capacitor]

What are voltage variable capacitors used for?

What is the nominal capacitance of a voltage variable capacitor?

It should be noted from the specification in Fig. 21-4 that the nominal capacitance has a large tolerance (400 pF to 600 pF), and this must be taken into account when using the C T / V R graphs. The major application of Voltage Variable Capacitors is as tuning capacitors to adjust the frequency of resonance circuits.

What is the difference between a fixed and variable capacitor?

A fixed capacitor has a specified value of capacitance and is not dependent on the frequency or amplitude of the applied signal. A variable capacitor can change its capacitance in response to an applied voltage. How does a variable capacitor work? A variable capacitor consists of two metallic plates separated by an insulator.

Can a variable capacitor be adjusted manually?

Variable capacitors like air capacitors and trimmer capacitors are adjustable manually. In contrast, the capacitance of a varactor diode is controlled by a reverse bias voltage. Since the controlling voltage can be applied automatically, manual tuning is no longer required.

What is a VVC capacitor?

VVCs helped launch digital radios and allow variable capacitance with no manual adjustment required. This article is part of The engineer’s complete guide to capacitors. If you’re unsure of what type of capacitor is best for your circuit, read How to choose the right capacitor for any application. What is a varactor diode?

What determines the capacitance of a variable capacitor?

The capacitance of a variable capacitor is determined by the overlapping area and distance between the rotor and stator plates. When the rotor plates are fully screwed into the fixed plates, the capacitance is at its maximum. Conversely, when the rotor plates are completely rotated out of the fixed plates, the capacitance is at its minimum.
