Below an explanation as to why and when and how snubber circuits are used. A snubber circuit may be needed if the circuit is connected to mains and the whole circuit is not allowed to induce RF (Radio Frequencies) back into the mains, for instance when lacking a proper mains filter. The reason a rectifier can do this (generate RF signals) is explained below.

The fIrst classification of snubber circuits is wheth-er they absorb energy in controlling a voltage or a current. A capacitor placed in parallel with other circuit elements will control the voltage across those elements. An inductor placed in series with other circuit elements will control the current through those elements.

Impact of Snubbers in Audio Amplifiers. Many DIYers are likely more concerned with any audible impact of the snubber than they are about eliminating RF emissions from the rectification. To address this concern, I designed an experiment to measure any impact of the snubber on the output of an audio amplifier.

The snubber circuit is composed of the following components: • A saturating reactor is used to protect the valve from di/dt stresses during turn-on. The saturating reactor offers a high inductance at low current and a low inductance at high currents. • A DC grading resistor R G distributes the direct voltage across the different thyristor levels. It is also used as a voltage …

It is called snubber circuit. Fig. 1: A snubber (RC) network is used for transient voltage protection. Every thyristor has maximum permissible value of $di/dt$. The thyristor can di be protected from excessive $di/dt$ by using an inductor in series as shown in Fig. 2. The inductance opposes for rapid current variations $di/dt$.

There is no doubt whatsoever that snubber circuits are essential in most SMPS circuits, because they operate at high frequencies and with very fast rise and fall times. Using a snubber on a mains transformer won't hurt anything, and in a (very) few cases it might be needed to ensure that a product meets EMI testing requirements.
Design of Snubbers for Power Circuits
https://www.cde.com/resources/technical-papers/design.pdf
these circuits, and in fact most power electronics circuits, have within them the same switch-diode-inductor network shown within the dotted lines. The behavior of this network is the same in all these circuits which means that we only have to solve the snubber design problem for one circuit to apply it to all of the others.

leakage inductance in the flyback transformer. Snubbers control the effects of the leakage inductance and improve the reliability of the power supply. Snubbers can be either passive or active networks. Passive snubber network elements are restricted to resistors, capacitors, inductors and diodes. Passive snubbers can control either voltage or current and

A snubber circuit is a proven way of reducing these transients and ensuring the protection of individual equipment and the wider system. Therefore, snubbers find their applications in many areas in a power system, in most cases becoming an indispensable component of it.

One more thought is that an RC snubber circuit can be utilized in combination with a bidirectional TVS diode of MOV. An RC snubber can be a highly efficient circuitry in limiting the initial voltage across the opening relay contacts, while the TVS or MOV may be a more efficient alternative for restricting peak surge voltages.
