Applications that demand stringent conditions on output dc voltage ripple require models that can accurately predict the magnitude of ripple at the output voltage. The paper analyses the impact of dc input ripple on the output ripple for Series Resonant Converter (SRC) using discrete domain sampled data modelling method. The paper presents a novel discrete state space and small signal model for SRC...
A modeling approach for the electrochemical batteries, which is suitable for in-circuit parameter extraction is presented. The charge flow in an electrode reaction is governed by the mass transport regime within the cells. For sufficiently higher charge flow rates, the mass transport rate decides the limit. Hence modeling the battery, centered around the mass transport mechanism can have the benefits...
The effect of non-idealities of a high frequency class D amplifier on it's output voltage is analysed. Firstly individual non-idealities like dead time, MOSFET body-diode drop, MOSFET ON-State drop, finite turn-on and turn-off time, series resistance of inductor and capacitor of output stage filter are taken one at a time and their effect on output voltage is analysed. Then effect of all of these...
