Self-precharge in single-leg flying capacitor converters [PDF]

, 2009
Flying Capacitor (FC) multilevel pulse width modulated (PWM) converters are an attractive choice due to the natural voltage balance property. During start-up of the converter, care has to be taken that the power switches are not exposed to voltage ...

A general approach to synthesis and analysis of quasi-resonant converters [PDF]

, 1991
A method for systematic synthesis of quasi-resonant (QR) topologies by addition of resonant elements to a parent pulse-width modulation (PWM) converter network is proposed.

Construction and analysis of causally dynamic hybrid bond graphs [PDF]

, 2013
Engineering systems are frequently abstracted to models with discontinuous behaviour (such as a switch or contact), and a hybrid model is one which contains continuous and discontinuous behaviours.

Directional photoelectric current across the bilayer graphene junction

, 2008
A directional photon-assisted resonant chiral tunneling through a bilayer graphene barrier is considered. An external electromagnetic field applied to the barrier switches the transparency $T$ in the longitudinal direction from its steady state value T=0

Switching converters with wide DC conversion range [PDF]

, 1991
In dc-to-dc conversion applications that require a large range of input and/or output voltages, conventional PWM converter topologies must operate at extremely low duty ratios, which limits the operation to lower switching frequencies because of the ...
