功放输出滤波电路疑惑

Csec

如下功放输出电路，输出的链路，有几个疑问：

RC Snubbers for Step-Down Converters
  W, k* K7 d. u4 z( C% M3 zVoltage spikes and ringing might be generated in a step-down converter at the turn-on or turn-off of a switching device. A snubber is a protection circuit that suppresses transient voltages that are produced when a current is turn on or shut off. Snubbers are used to suppress voltage spikes caused by the switching of not only mechanical switches but also transistors and diodes. Snubbers protect not only switching devices but also other electronic parts and reduce switching noise. An RC snubber uses a resistor in series with a capacitor and is connected in parallel with a device that is subject to voltage spikes.
