R-C Snubbing for the Lab

资料介绍
源的效率上升,电路电阻往往下去。这可能会产生高频电路有可能产生大的电压过冲和衰减时间长。它可能会导致在半导体过电压的压力,这限制了电路的效率和可靠性。

APPLICATION NOTE 907
R-C Snubbing for the Lab
As the efficiency of power supplies goes up, circuit resistances tend to go down. This can create high-frequency
circuits with the potential to generate large voltage overshoots and long decay times. It can cause over-voltage
stress in the semiconductors, which limits circuit efficiency and reliability.

Snubbing these high-frequency circuits with a simple resistor-capacitor network provides damping, which
minimizes ringing and over-voltage stress.

The basic circuit illustrated in Figure 1 serves as a useful model. L1 and C1 form a resonant circuit that is
damped by RL. In an actual application it……
