The snubber capacitors acts as a low-pass filter in a circuit, absorbing the peak voltage. Usually used in insulated gate bipolar transistors (IGBT), to eliminate the spike voltage caused by the stray inductance of the bus, to avoid the damage of insulated gate bipolar transistors.

What is a buffer capacitor?

 

The buffer capacitor is a capacitor connected to the high current switch node to reduce the parasitic inductance of the electrical wiring. Parasitic inductance will cause large surge when the switch is turned off (cutting off the current). When the surge exceeds the rated value of components, it may even cause product damage.

 

To effectively reduce the wiring inductance, the component pins in the circuit close to the red ellipse of the circuit diagram should be connected to the capacitors.

 

Capacitance characteristics:

 

Single metal buffer capacitor and bimetal buffer capacitor are available.

 

Capacitor application:

 

1. in power electronics applications, buffer capacitors are responsible for reducing electromagnetic interference by clamping voltage and current ringing.

 

1. in order to reduce stray inductance, the buffer is installed on the IGBT module, and a buffer capacitor is provided in the configurable terminal to achieve versatility.
