Inductor-less half-bridge piezoelectric transformer based resonant converters can offer considerable reductions in mass and form factor over their discrete counterparts. This work presents an analytical model for calculating the load and frequency range over which such converters can achieve ZVS given the large input capacitance these transformers typically present.
The objective of this paper is to demonstrate a fully digital controller for interleaving DC/DC converter. In this paper, a new adaptive control method is proposed to improve the dynamic performance in rapid load current slew rate requirement. This control architecture is according to PID controller with Gain Scheduling architecture and based on pole-zero cancellation method to build the parameters...
In this paper, a novel converter, named negative-output KY buck-boost converter, is presented herein, which has no bilinear characteristics. First of all, the basic operating principles of the proposed converter are illustrated in detail, and secondly some simulated and experimental results are provided to verify its effectiveness.
A novel converter, named negative-output KY boost converter, is presented here in, which needs one additional capacitor and one additional diode as compared to the boost converter. In the following, the basic operating principles of the proposed converter are illustrated in detail, together with some simulated and experimental results to verify its effectiveness.
The main purpose of this paper is to develop a photovoltaic simulation system with maximum power point tracking (MPPT) function using Matlab/Simulink software in order to simulate, evaluate and predict the behaviors of the real photovoltaic system. A model of the most important component in the photovoltaic system, the solar module, is the first to have been established. The characteristics of the...
Computational fuel cell dynamic (CFCD) modeling is considered the most accurate tool for a better FC design and understanding. CFCD models have already proved the effect of the water membrane content in the dynamic response of a proton exchange membrane (PEM) FC. However, these models require high computational resources and they are not easy to interconnect with the usual electrical circuit simulation...
This paper discusses the importance of a simulation study of the Taiwan Electrical Fuel Cell Power Scooter. This study applies a more detailed modeling which is complex as existing modeling methods, yet not more difficult to solve numerically. In most simulation studies, the influence of non-linearity (for example, saturation, losses, reluctance effects) of the power electronics and electrical machine...
With the increasing complexity of the circuits it is essential that students work on the experiments which enhance their circuit analysis and design skills. Circuit simulation tools like PSpice and Multisim are extremely useful tools in understanding the operation of the circuits. However undergraduate level simulation experiments are limited to very simple experiments and mostly concentrate upon...
