How to Keep a FLYBACK Switch Mode Supply Stable with a Critical‐Mode Controller
INTRODUCTION Switch Mode Power Supplies (SMPS) can operate in two different conduction modes, each one depicting the level of the current circulating in the power choke when the power switch is turned on. As will be shown, the properties of two black boxes delivering the same power levels but working in different conduction modes, will change dramatically in DC and AC conditions. The stress upo...
متن کاملA 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 کاملModelling of a Switched Mode Power Supply using VHDL - AMS – A Hardware Descriptive Language
This paper provides an overview of the VHDL AMS hardware description language for analog and mixedsignal applications like the switched mode power supply which is designed by describing the major elements or components of the system with the help of this hardware descriptive language and illustrating it using Hamster which is a simulation software for VHDL and Verilog Descriptive Language. Inde...
متن کاملSwitched-Mode Power Converters
A new modeling approach for the spectral analysis of pulsewidth modulated (PWM) converters with independent inputs is developed. The key of this approach is to extend the Volterra functional series to nonlinear systems with multiple independent inputs. After formulating the state-space equations describing the dynamical behavior of PWM converters, the Volterra transfer function characterizing t...
متن کاملDesign of Observer-based H∞ Controller for Robust Stabilization of Networked Systems Using Switched Lyapunov Functions
In this paper, H∞ controller is synthesized for networked systems subject to random transmission delays with known upper bound and different occurrence probabilities in the both of feedback (sensor to controller) and forward (controller to actuator) channels. A remote observer is employed to improve the performance of the system by computing non-delayed estimates of the sates. The closed-loop s...
