These two capacitors are in series, so the e ective capacitance between transmitter and receiver is C=2. An H-bridge driver converts VS into an AC voltage to enable current ow through the capacitors. Induc-tors L are placed in series with the coupling capacitance to enable soft-switching.
What role do capacitors play in an electronic circuit?
Therefore, capacitors play the three following important roles in an electronic circuit. Capacitors can charge and discharge because of the structure. Featured by the electric charge and discharge, capacitors also can be used as a power supply. Camera flashes utilize this feature of capacitors.
How does a capacitor work?
A capacitor typically consists of an insulator with two metal plates attached on both sides of the insulator. Insulators do not conduct current. The insulator used in capacitors is called a dielectric. The positive and negative charges are transferred within the conductor during the flow of electricity.
What are the properties of a capacitor?
It may contain outdated technical information and references to products not currently available from TDK. The two basic properties of a capacitor are that it can store electric charges and that it passes higher-frequency AC currents more easily. However, in high-frequency ranges, the capacitor begins to reveal a different side.
What is a capacitor used for?
However, the converted DC is an unstable current that includes ripples. A capacitor is used to remove these ripples and maintain a constant voltage. The flow of AC in a capacitor is useful for noise reduction. In general, since the noise in DC is an AC component with high frequency, it tends to go through the capacitor easily.
Why are capacitors used at low frequencies?
The impedance of a capacitor at low frequencies is very high, thus the common-mode current that can pass through the interface is limited. Therefore, capacitors can be used to give the isolation property, and power can be transferred at a much higher frequency.
