This work introduces and discusses the issues of several common startup techniques for boost dc-dc converters. Moreover, basic operating principle of boost converters and three kinds of startup techniques will be briefly introduced in this work, and then an improved method is presented. The mathematical models of two chosen startup methods are built, and MATLAB simulation is used for comparison. In...
This paper proposed a solid-duty-control technique in the boost converter to keep a constant duty control to reduce dip voltage during load transient period. Besides, due to variable transient enhancement controller, fast transient response is achieved. The proposed SDC technique can provide a stable and regulated output for edge-lit LED backlight systems. Compared to conventional design without any...
In this study, the design of planar symmetric balance circuit and perform the high-balance differential output frequency response for system-in-package (SiP) application using the integrated passive device (IPD) technology are proposed. Passive balun with single-end input and differential output is an important device in RF front-end communication system. The merits of passive component are no power...
Current feedback compensation technique (CFC) can adaptively adjust the phase margin for achieving better transient response than that with variant phase margin at different load current conditions. Not only fast transient response is attained due to suitable phase margin but also the minimum load current limitation can be greatly reduced to about 50 muA without sacrificing bandwidth at light load...
