Basic circuits to design switched-based DC-DC converters
نویسنده
چکیده
The purpose of this paper is twofold. On one hand, basics on switched circuits for designing a DC-DC converter are presented and, on the other hand, power electronics definitions associated with simple electrical networks are mentioned. In the analysis of these networks, it is necessary to take into account not only converters’ non-idealities but also how to minimize power losses. Since power losses may be minimized by increasing the clock frequency of switched-based converters, experimental results of basic clock generators are presented. These generators were implemented with low-cost components.

A Robust Controller For DC-DC Switched Mode Power Converters
Power converters often consist of linear circuits that are switched between two configurations. Even though each of the configurations is linear, the overall behavior of the circuit is nonlinear. DC-DC switched mode power converters constitute simple but yet efficient means of DC power regulation [ 1,2]. The analysis and control of such a circuit is fairly complicated. Different methods have be...
متن کاملA Transformerless Boost Converters with High Voltage Gain and Reduced Voltage Stresses on the Active Switches
Usually basic dc-dc boost converters are unable to provide high step up voltage gain due to the effect of power switches, rectifier diodes and equivalent series resistance of inductors and capacitors and the voltage stresses on the power switches are high. This paper proposes a simple transformerless dc-dc converters to achieve high step up voltage gain without an extremely high duty ratio. The...
