Brief review on snubber circuits
2010 20th International Conference on Electronics Communications and Computers (CONIELECOMP), 2010This paper presents a summary of the main types of snubber circuits; generally classified as dissipative and non-dissipative or active and passive snubbers. This type of circuits are commonly used because of they can suppress electrical spikes, allowing a better performance on the main electrical circuit.

An evolution of regenerative snubber circuits
2000 IEEE 31st Annual Power Electronics Specialists Conference. Conference Proceedings (Cat. No.00CH37018), 2002The use of switching regulator circuits at high power levels and high frequencies requires careful examination and control of the power dissipation during switching. In this paper, the authors show the process in which the PWM soft-single-switched converters were created. They operate with soft switching in a pulse width modulation way.

Snubber Circuit for Marine Controlled-Source Electromagnetic Transmitter
Journal of Shanghai Jiaotong University (Science), 2021A high-power marine controlled-source electromagnetic transmitter (HP-MCSET) transmits a high-frequency conversion current on the sea floor. Some problems exist when the direct-current to alternating-current (DC-AC) launch bridge (LB) is used in the marine controlled-source electromagnetic transmitter (MCSET).

A novel lossless snubber circuit
Proceedings, Fourth Annual IEEE Applied Power Electronics Conference and Exposition, 2003A simple lossless snubber circuit for use with a switch mode power converter is presented. The circuit uses a capacitor connected between the primary and tertiary windings of a transformer in such a way as to relieve the stress from the power semiconductor switch at both turn-on and turn-off.

Equivalent Circuit Analysis for Core Snubber
IEEE Transactions on Plasma Science, 2012An equivalent circuit for a core snubber is established in this paper. The circuit can approximately express a parallel resistance and inductance. The resistance can be directly calculated according to the resistivity of the magnetic core and structure dimensions of the core snubber referring to Fink-Baker-Owren (FBO) method, and the eddy current ...

Non-linear capacitors in snubber circuits for GTO-thyristors
20th Annual IEEE Power Electronics Specialists Conference, 1992Applications with GTO (gate turn-off) thyristors have until now required snubber circuits, at least for turn-off. At high switching frequencies there are conflicting design criteria for the snubber capacitor, concerning losses versus timing conditions. To improve this situation the authors use nonlinear capacitors.

Inverter circuit with the regenerative passive snubber
2007 Power Conversion Conference - Nagoya, 2007This paper presents an inverter circuit using a snubber circuit to achieve soft switching. This snubber circuit has a transformer-based energy regenerative circuit. This circuit has no additional switching device, and the cost is low. In this paper, this circuit was examined and evaluated by single shot test and PWM drive test.
