The present invention relates to the field of sensor technology and discloses a centrally perforated annular ceramic capacitor, wherein the annular capacitor is formed by fusing and sintering a ceramic base and a ceramic reaction membrane, and wherein the axes of the ceramic base and the ceramic reaction membrane are each provided with through holes to provide a mounting channel for the circuit elements to be assembled, so that the annular capacitor can be more conveniently integrated into the complex circuit of the temperature-pressure sensor in order to simplify the overall structure of the temperature-pressure sensor, including the circuit and sealing structure, in this way giving the temperature-pressure sensor a structure of automated assembly in order to reduce manufacturing and assembly costs;In comparison to the disc-shaped ceramic capacitor without a through-hole in the middle, the toroidal capacitor with the arrangement of the first ring circuit and the second ring circuit has a higher initial value and a greater amount of change, so that the toroidal capacitor has a wider measuring range and a finer pressure sensing gradation to improve the accuracy of pressure detection.

The application provides an anti-ringing circuit and a DC-DC converter. The anti-ringing circuit is applied to the DC-DC converter, and comprises multiple-stage anti-ringing branches and a matching branch. The multiple-stage anti-ringing branches are connected in parallel with each other, and the matching branch is connected in series with the multiple-stage anti-ringing branches connected in parallel at both ends of an inductor of a main circuit of the DC-DC converter. Each anti-ringing branch comprises a switch tube and a resistor connected in series. The matching branch comprises a matching switch tube. When the switch tube in any one-stage or multiple-stage anti-ringing branch is turned off, the resistor in the one-stage or multiple-stage anti-ringing branch is disconnected with the inductor. When the switch tube in any one-stage or multiple-stage anti-ringing branch and the matching switch tube are turned on, the resistor in the one-stage or multiple-stage anti-ringing branch is connected in parallel with the inductor. The application can flexibly adjust the current in each anti-ringing branch.
