Snubber Circuits Suppress Voltage ... - Maxim Integrated
pdfserv.maximintegrated.comsnubber diode to charge the capacitor to the rail. At that time, it is expected that the output rectifier will turn on. When the switch turns on, the snubber capacitor will discharge through the snubber resistor and the switch. The capacitance value is obtained from IP = C (VC/ tr) Where VC = voltage across the capacitor and tr = rise time of ...

The device nevertheless continues to discharge C H until V out approaches zero. We note that for V out 2 (DD TH), the transistor can be viewed as a resistor equal to R on ...
Chapter 16 Oscillator Circuits and Applications
staff.utar.edu.myThe capacitor begins to charge until the voltage V C is just greater than the feedback voltage V f, which is out 2 3 3 V R R R +. At this point, the output of the op-amp is swung to minimum negative value, which is the negative saturation voltage of the op-amp. This would cause the capacitor to discharge. When the voltage V C reaches negative
