Abstract:

A series of seismic tests of mechanical snubbers on a full-scale model piping system provided a unique opportunity for detailed scrutiny of snubber seismic behavior on an actual piping system. The observed snubber behavior is a complicated pattern of braking and releasing, drag and drift, and the dynamic characteristics of the snubber, as well as the input motion, play a role in the response of the snubber. The snubbers were effective in limiting pipe displacements. Relative accelerations across the snubber were larger than expected. Snubber hysteretic behavior was irregular. Results from this

Abstract:

This paper presents a systematic approach to developing turn-off snubber for an interleaving converter to smooth out switch turn-off transition. With the approach, the interleaving converter with two turn-off snubbers, which are formed by two L-C-D type snubbers, can be replaced by the one with turn-off snubber composed of a single-capacitor snubber. It can be used in the basic six interleaved converters, such as buck, boost, buck-boost, ‘cuk, zeta and sepic converters. In this research, the structure of the interleaved converter with the turn-off snubber can be conveniently simplified from th

Abstract:

In this article both the general linear regenerative turn-on and turn-off snubbers are analysed and optimized independently from one another, in terms of minimum energy losses. The dissipative snubber - which was up to now the only optimized snubber - now becomes merely a special case of this general regenerative snubber. Equations describing the most important parameters are presented in tables, while some energy versus snubber size graphs are also shown.

The damping coefficients and ratios of piping system snubber supports were found to vary logarithmically with pipe support nodal displacement. For piping systems with fundamental frequencies in the range of 0.6 to 6.6 Hz, the support damping ratio for snubber supports was found to increase with increasing fundamental frequency. For 3-kip snubbers, damping coefficient and damping ratio decreased logarithmically with nodal displacement, indicating that the 3-kip snubbers studied behaved essentially as coulomb dampers; while for the 10-kip snubbers studied, damping coefficient and damping ratio i

Abstract:

A Flyback converter is a simple switch-mode power supply that can be used to generate a DC output from either an AC or DC input. The converter switch is the most critical part of any converter. The voltage stress across the switch is a major issue as the high voltage spikes occur due to interaction between its output capacitance and the leakage inductance of the transformer. These spikes can be reduced with various snubbers like conventional tertiary winding, Resistor Capacitor and Diode(RCD) snubber, energy regenerative snubber and an active clamp snubber.

Abstract:

The Ritz averaging method is utilized to reduce the nonlinear characteristics of piping system supports (snubbers) to equivalent linear support stiffnesses during seismic excitation. The equivalent snubber support stiffnesses are used in seismic modal analyses of two piping systems. The analyses are performed in order to determine the effect that high snubber lockup velocities have on piping system stresses. The results show that the lockup velocity of snubbers in the systems analyzed can be safely allowed to increase above normal limits without any significant increase in nodal stresses.

When flyback converters are connected to floating loads, voltage swings at the output can give rise to spikes which pass through the flyback transformer stray capacitor. This happens when flyback converters supply IGBT floating gate drivers. These voltage spikes can interfere with the correct behavior of the gate driver. In order to reduce the transformer stray capacitance, the two windings must be wound on the opposite sides of the core. However, this reduces the coupling factor of the transformer by increasing its leakage inductance and snubbers must be employed in some cases. This paper dea

This technique reduces the number of components and also returns some of switching energy to SEPIC converter. The mathematical analysis and optimization of LC snubber with respect to number of turns is also presented. Spice simulations and experimental results are provided to verif

Abstract:

This paper presents a high-efficiency GaN-based 65 W Quasi-Resonant (QR) Flyback converter. The converter is characterized by a wide input voltage range and a variable output voltage, and it is designed as a Switch Mode Power Supply (SMPS) for high power density USP-Power Delivery (USB-PD) applications. To increase the efficiency and power density, a regenerative snubber clamp solution has been used to limit the excursion of the drain voltage during the power switch turn-off. The activity involved the modeling of the converter, the sizing of the regenerative snubber, and the design of the flyb

Abstract:

This paper presents a selection of inductor and snubber capacitor in non-isolated synchronous DC-DC switching power converter. The circuit is made to operate in Synchronous Discontinuous Conduction Mode (SDCM)/Forced Continuous Conduction Mode (FCCM) of operation for minimum inductor value, to reduce the size, weight and cost of the converter. The turn off loss of the switch induced by SDCM of operation is minimized by connecting snubber capacitor across the transistor switch. Before the switch is turned ON, snubber capacitor requires certain amount of energy must be stored in the inductor to

Abstract:

This paper presents the comparison of resonant and passive lossless snubber circuits implementation for DC-DC boost converter to achieve soft-switching condition. By applying high switching frequency, the volume reduction of passive component can be achieved. However, the required of high switching frequency cause the switching loss during turn-ON and turn-OFF condition. In order to reduce the switching loss, soft-switching technique is required in order to reduce or eliminate the losses at switching devices. There are various of soft-switching techniques can be considered, either to reduce th

Abstract:

This paper describes a high-frequency soft-switching dc-dc converter with a simple energy recovery capacitor snubber on the secondary side. The presented dc-dc full-bridge converter with the energy recovery snubber removes the main drawbacks of the classic Phase Shifted PWM (PS-PWM) dc-dc converter, e.g., the circulating current flowing during the free-wheeling interval and dependency of the soft switching on the load current. The converter utilizes a full-bridge topology with pulse-width modulation and a centre-tapped full-wave controlled rectifier with one active switch. The zero-voltage swi

Abstract:

Prior to 1982, pipe damping values in nuclear plants were prescribed by Regulatory Guide 1.61 and Appendix N to Section III of the ASME Boiler and Pressure Vessel Code. In the early 1980s, it became clear that piping design was too conservative resulting in systems that had far too many supports, particularly snubbers. These supports were costly to design, install, and inspect; contributed to increased worker radiation exposure; and since snubbers sometimes lock when unloaded causing higher fatigue usage in piping, the safety margin of the systems was reduced. A series of steps was undertaken

Abstract:

Conventional buck-boost converter designs often suffer from efficiency losses and performance degradation due to switching transients and voltage spikes. To address these challenges, we propose the incorporation of a snubber circuit, which is designed to absorb and mitigate these detrimental effects. The study involves the design, implementation, and experimental evaluation of the proposed enhanced buck-boost converter. The analysis focuses on the impact of the snubber circuit on key performance metrics, including efficiency, thermal behavior, and electromagnetic interference (EMI) reduction.

Abstract:

In this study, we offer a new isolated bidirectional converter., which utilizes a novel snubber to provide soft switching for both primary switches without introducing additional energy losses to the snubber circuitry. The suggested converter has a low number of components and its control is simplified due to the fact that only one switch operates on each side. The performance of the proposed converter has been thoroughly analyzed and validated through simulation using PSPICE software, confirming the theoretical analysis of the converter.

Abstract:

A novel suggestion for a non-linear turn-off snubber is simulated experimentally with linear capacitors and an auxiliary power electronic switch. Thus the principle and advantages of this concept is partly illustrated, particularly concerning the important reduction of reactive stored energy for the same switching dissipation in the main power device. The full advantages of the concept will be realised when a snubber capacitor with non-linear, voltage dependent dielectric is used. The work on this part of the solution is being continued.

This paper presents a new single-stage single-switched forward converter with magnetic coupled nondissipative snubber, which gives good power factor correction (PFC), low current harmonic distortion, and tight output voltage regulation. The proposed converter features low switch current and voltage stresses, essential for the design of a single-stage power factor correction converter. The prototype shows that the IEC1000-3-2 requirements are met satisfactorily with nearly unity power factor.
