Snubber Capacitor Calculator. Empirically choose the snubber capacitor c snub equal to twice the sum of the switch output capacitance and the estimated mounting capacitance. Then the generated resistance loss 12 h ì ç h 8 â ç is equal to the energy that is charged in the snubber resistor rsnb.
Depending on the performance examination of this capacitor you can increase it until the capacitance is sufficient. S times the number of voltage transi tions per cycle. In the snubber capacitor csnb.
There are multiple methods to assess the performance of the chosen snubber values.
Snubber circuit design calculators driving inductive loads with transistor switches whether they be flyback transformers relays or motors often result in the high voltage resonant spikes when the coils are interrupted from their current current source by the transistor. Empirically choose the snubber capacitor c snub equal to twice the sum of the switch output capacitance and the estimated mounting capacitance. Capacitor dc voltage class the maximum continuously applied dc voltage can be the rated dc voltage of the capacitor in order to ensure longer life of the capacitor.
