New snubber circuit with passive energyrecoveryfor power inverters

open access: yesIEE Proceedings - Electric Power Applications, 1996
The paper proposes a new passive circuit for partial snubber-energy recovery in GTO thyristor high-power voltage-source inverters. The analysis and simulations show that the proposed bridge-leg snubber circuit can recover greater than sixty five per cent of the total snubber energy, as well as the freewheel diode reverse recovery energy. This energy is

Comparison of Surge Voltage Reduction and Economic Efficiency of DC SSCBs According to MOV and RCD Snubber Combination

open access: yesIEEE Open Journal of the Industrial Electronics Society
Metal oxide varistor (MOV) is a nonlinear resistive element whose resistance decreases rapidly when the applied voltage exceeds a threshold value. A dc solid-state circuit breaker (SSCB) uses MOVs or MOV with resistor-capacitor-diode (RCD) snubber ...

An IGBT turn-on snubber circuit with passive energy recovery

open access: yesInternational Journal of Electronics, 1998
An inductive turn-on snubber with passive energy recovery for IGBTs used in single ended applications and asymmetrical half bridges is presented. Snubber inductive stored energy at switch turn-off is passively recovered into the load. In so doing, limited capacitive turn-off snubbering is inherently achieved, which reduces IGBT voltage during its tail ...

Computer-aided design of power transistor inverter snubber circuits

open access: yesIEE Proceedings B Electric Power Applications, 1987
The conventional voltage-source inverter snubber circuit has been examined in detail by computer simulations. A new snubber arrangement is proposed and analysed. It aims to reduce the transient voltage overshoot without incurring excessive switching losses.

PSPICE modelling and design of a snubber circuit for the matrix converter

open access: yesInternational Journal for Engineering Modelling, 2000
In matrix converters one of the basic commutation strategies is the dead time current commutation. Although the application of this commutation strategy is simple and easy, the design of snubber parameters becomes crucial to control the voltage spikes across the switches due to the open circuiting of the motor winding during the dead time.
