The snubber resistance
WebMay 5, 2016 · The seven-step procedure shown in Table 1 uses a common methodology that shifts the resonant frequency of the ringing to calculate the circuit’s parasitic … WebAug 4, 2024 · So, if you half the capacitance, you must double the resistance. Given this well-known formula for capacitor energy (W): -. W = 1 2 ⋅ C V 2. You can re-arrange for voltage: -. V = 2 ⋅ W C. So, if you halved the capacitance, voltage would rise by 2. The power dissipated by the resistor would be related to the peak voltage thus: -. P = V P K 2 R.

WebJul 14, 2024 · Let’s see what happens with the method proposed in this paper, which consists of three main steps. Calculate the required gain from Eq. (32). Gsnb = 0.717, i.e. the snubber needs to reduce the Vx peak to 71.7% of the existing Vx peak level. Calculate Csnb with Eq. (39). In this case, Csnb > 1.3nF. Let’s use Csnb = 1.5nF for this example.
WebMay 24, 2024 · 2 Answers Sorted by: 4 This snubber circuit is used to limit dv/dt during turn-off of the switch by presenting a higher load capacitance to the inductive load usually driven by the transistor. Without the snubber, the rate would be more or less only limited by the difference of load and switch current and the output capacitance of the switch.
