6 FAQs about [Capacitors isolate DC]
Can a Cy capacitor be used to isolate a DC-DC converter?
A typical isolated DC-DC converter has two contradictory requirements: - So, CM noise on the output can be kept low by using the CY capacitor but, maintaining a high isolation impedance at high frequencies be achieved using the CY capacitor. So, it's a compromise. would the intended use of the Y-cap be achieved if a higher value like 1nF is used?
What is a capacitive isolator?
e isolation barrier. A capacitive isolator’s inability to pass DC signals makes it inherently the right choice for isolation, which is why it is widely used in sensitive and important applications, such as telecom nd industrial power. Capacitive isolators are not susceptible to magnetic noise but can maintain high data rates and keep p
What is an isolated DC/DC converter?
The isolated DC/DC converter uses an open-loop control approach that simplifies the design and makes the optocoupler superfluous. The single-sided, populated PCB is a convenient tool for evaluation of the design.
What is a dedicated capacitor?
A dedicated capacitor, CDC_BLOCK, blocks any DC voltage on the primary winding that might otherwise cause flux walking and saturation of the transformer core. The transformer T is the main passive component of the design and provides the isolation between the primary (non-isolated) side and the secondary (isolated) side.
How does capacitive isolation work?
Capacitive isolation offers an easy solution to this. If the flyback control is generated at the secondary side, the controller can sense the turn-off of the synchronous rectifier (SR) and turn on the flyback quickly through the capacitive isolation link.
