Switching power supply plus Y capacitor will affect efficiency?

In different application states, the state of the capacitor is different. Switching power supply and Y capacitor are common in our life. Today, the editor wants to talk to you about the switching power supply and Y capacitor will affect the efficiency? The answer is no.

The Y capacitor is used in the switching power supply for common mode filtering. It is connected between L or ground and N to ground to filter the common mode signal of L to ground or N to ground. The Y capacitor is usually used symmetrically. Road; decoupling; filtering; energy storage. As far as the efficiency mentioned is concerned, the engineering needs to understand the loss mechanism generated in the conversion circuit in order to find a way to reduce the loss. In addition, the project is also familiar with the various characteristics of switched capacitor components to select the appropriate chip to achieve efficiency indicators.
