Rc Snubber Module. Forward polarized rc snubber circuit for an appropriate forward polarized rc snubber circuit a thyristor or a transistor is connected with an anti parallel diode. Snubber considerations for igbt applications by yi zhang saed sobhani rahul chokhawala international rectifier applications engineering 233 kansas st el segundo ca 90245 usa abstract snubber circuits can be used to protect fast switching igbts from turn on and turn off voltage transients.
Preventing electromagnetic interference and increasing the anti jamming capability of the microcontroller. A simple rc snubber uses a small resistor r in series with a small capacitor c. R will limit the forward dv dt and r1 limits the discharge current of the capacitor when transistor q1 is turned on.
However if a large enough spike is introduced it can damage the snubber capacitors.
Rc absorption snubber circuit module only other accessories demo in the picture is not included. It does this by limiting the rate of rise in voltage dv dt across the thyristor to a value which will not trigger it an appropriately designed rc snubber can be used with. Rc absorption snubber circuit module only other accessories demo in the picture is not included. These are used as overvoltage snubbers to clamp the voltage.
