Journal ArticleDOI
Characterization and Experimental Assessment of the Effects of Parasitic Elements on the MOSFET Switching Performance
TL;DR: In this paper, a circuit-level analytical model that takes MOSFET parasitic capacitances and inductances, circuit stray inductances and reverse current of the freewheeling diode into consideration is given to evaluate the switching characteristics.
Journal ArticleDOI
An Active Low-Loss Motor Terminal Filter for Overvoltage Suppression and Common-Mode Current Reduction
TL;DR: In this article, an active terminal filter was proposed to reduce the voltage surges and alter the rise time of the voltage pulses at the motor terminals, which can perform the same functions as the passive filters with low power dissipation.
Journal ArticleDOI
An Investigation Into the Effects of the Gate Drive Resistance on the Losses of the MOSFET–Snubber–Diode Configuration
TL;DR: In this paper, the effects of the gate drive resistance on the losses of the MOSFET-snubberdiode (MSD) configuration commonly used in many power converters are investigated.
Proceedings ArticleDOI

TL;DR: In this article, a motor protection filter with energy recycling was proposed, which can protect the motor against insulation damage and works out the drawbacks of most recent passive filter networks such as RLC filter and RC filter.
