This paper introduced the operation principle of current mode control boost converter. The equations of two different work states were built by applying the theory of KCL and KVL. Two models working in CCM and DCM were respectively established using Matlab/Simulink and the nonlinear phenomenon of boost converter can be observed through simulation. The results of theoretical analysis are corresponded...
Photovoltaic (PV) system is composed of several elements as solar cells, boost converter, inverter and load. Owing to the existence of converters, photovoltaic system is a hybrid system contains continuous dynamic and discrete dynamic. Traditionally, the power electronic converter is difficult to model. This paper illustrates the modeling method of hybrid system, especially finite automata model....
A modeling approach of a power factor correction circuit operating in boundary conduction mode is presented. The PFC is controlled by a constant on-time of the switch. The effect of valley switching is simplified and taken into account as dead-time to generate a large signal model. On the basis a small signal model for the constant on-time controlled PFC voltage loop is derived. The large and small...
