This work derives the closed-loop input and output impedances of three major types of DC-DC converters (Buck, Boost, and Buck-Boost) operating in voltage or current mode control. First, it introduces the small-signal converter model employed to derive the input and output impedances. Next, it reviews open-loop impedances for use in simplifying the expressions developed for closed-loop impedances....
The design of a Single Inductor Dual Output (SIDO) buck converter using two individual voltage mode control loops has been presented in this paper, and the limitation of using such control method has been indicated, then the control schemes for minimizing the cross regulation issue has been discussed. By using two separate control loops, the inductor energy is shared and regulated for both output...
This paper investigates a mathematical model of a boost converter based on three-state switching cell and voltage multipliers cells (mc). The proposed analysis is based on the tool ??PWM-switch modeling of DC-DC converters??. Two situations are analyzed: operation with one voltage multiplier cell (mc=1) and operation considering the number of voltage multiplier cells greater than 1 (mc>1). The...
DC-DC converters are the kernel parts in the switching power supplies. There are abundant dynamical behaviors in them. In order to discover all these linear and nonlinear phenomena, it is demanded to put forward some appropriate modeling methods. This article discusses the modeling methods, which aimed at some familiar DC-DC converters under the control of voltage and current mode. They include exact...
