AC Coupling. Capacitive voltage dividers can be used for AC coupling, which involves removing the DC component of a signal while allowing the AC component to pass through. What factors should be considered when choosing capacitors for a voltage divider? When choosing capacitors for a voltage divider, consider factors such as capacitance
Thereby there is no need for separate coupling capacitors. Capacitor Voltage Transformers also serve as coupling capacitors for coupling high-frequency power line carrier signals to the transmission line. These capacitors form a voltage divider (2, 3) between the high voltage terminal (1) and the high-frequency terminal (4).

Because the input capacitor in a buck converter is part of the critical paths (hot loops) for this topology, C BYP has to be connected with as little parasitic inductance as possible. Thus, the placement of this component is important.
Coupling Capacitors: The coupling capacitors (C 1 and C 3 in Fig. 12-1) should have a negligible effect on the frequency response of the circuit.
