Nonequilibrium depinning transition of ac driven vortices with random pinning
New Journal of Physics, 2017 We study the critical behavior associated with transient dynamics of vortices near the depinning transition by an ac drive. From ${I}_{{\rm{ac}},{\rm{e}}}$ – ${V}_{{\rm{ac}},{\rm{e}}}$ curves at different frequencies f , where ${I}_{{\rm{ac}},{\rm{e ...

Generalized Carrier-Based PWM Method for a 12-Switch Converter
Open Engineering, 2016 This paper proposes a generalized carrier-based pulse-width modulation (CBPWM) method for a 12-switch converter feeding three independent loads. The converter topology is part of the (3N + 3)-switch converter family where N is the number of outputs (N ...
