Modeling and Optimization of Impedance Balancing Technique for Common Mode Noise Attenuation in DC-DC Boost Converters

Benchmark: DC-to-DC Switched-Mode Power Converters (Buck Converters, Boost Converters, and Buck-Boost Converters)

Power electronics represent a large and important class of hybrid systems, as modern digital computers and many other systems rely on their correct operation. In this benchmark description, we model three DC-toDC switched-mode power converters as hybrid automata with continuous dynamics specified by linear ordinary differential equations. A DC-toDC converter transforms a DC source voltage from ...

A Power Model for DC-DC Boost Converters Operating in PFM Mode

Existence of horseshoe maps in current-mode controlled buck-boost dc/dc converters

In this paper, a buck-boost dc/dc converter under a typical current-mode control is studied. The existence of chaos is proven theoretically in this system. The proof consists of showing that the dynamics of the system is semiconjugate to that of the one-sided shift map, which implies positive entropy of the system and hence chaotic behavior. The essential tool is the horseshoe hypotheses propos...

Soft Switching Analysis in Dc-dc Boost Converters

The boost topology is the most popular topology used in power factor correction circuits. The efficiency and performance of the boost converter depends on the switching frequency affecting the switching losses. At high frequency operations the switching losses of the converter is considerable and decreases the efficiency of the converter. To remove this problem the converter is designed to oper...

Discrete Sliding Mode Control for DC-DC Converters with Uncertainties

A discrete-time sliding mode controller is presented for DC-DC converters. A criterion for the existence of the sliding surface is derived based on the LMI technique combined with the Lyapunov method. In addition, the design of sliding mode control is presented according to the reachability condition. The control law can effectively constrain the input disturbance and reduce the effects from th...
