Several topologies have been proposed for combining batteries and ultracapacitors (UC) to build a hybrid energy storage system (HESS). It is essential to quantify the performance benefits of these different circuit topologies. This will establish a metric for evaluating the performance of new topologies as well as providing the basis to select a certain topology and design a HESS optimized for the...
Variable active passive reactance (VAPAR) is nonlinear time varying system which can generate virtual variable inductance including negative values in power circuits. AC source of VAPAR causes sinusoidal states in circuit then the circuit has not one fixed point in source period. And modified Poincare map must be used for modeling of these systems. The OGY method is used for controlling of chaos....
In power electronics, design of power supply is always tending to miniaturization. Passive components represent the main part of the volume. Integrating these elements is a major keypoint to reach a high level of reduction. In order to achieve this, different works have already begun in the world (Chen, 2003). In this paper, we present research on volumes of passive components reduction, inductor-transformer-capacitor...
