Types of Snubber Circuits
There are two configurations of snubber circuits . They are
- RC snubber circuit
- RCD snubber circuit
RC Snubber Circuit
This is the most commonly used snubber circuit which consists of a resistor and a capacitor connected across the diode . When the diode is turned off ,the inductive load tries to maintain the current flow that causes rapid change in voltage across the diode which leads to voltage spikes .It provide a path for the transient current through RC combination. The resistor limits the current flow through the capacitor that prevents excessive discharge currents .The capacitor absorbs energy from voltage spikes and suppress the voltage rise.

RCD Snubber Circuit
The construction of RCD snubber circuit is similar to RC snubber circuit with additional diode connected in parallel .This is used for highly inductive loads .Here the diode provides the low impedance path for the discharge current and suppress the voltage spikes . It helps to absorb and dissipate the transient energy and suppress voltage spikes by allowing transient current to bypass the diode being protected.
