AbstructThis paper describes the design of a CMOS capacitor-ratio-independent and gain-insensitive algorithmic analog-to-digital (A/D) converter. Using the fully differential switched-capacitor technique, the A/D converter is insensitive to capacitor-ratio accuracy as well as finite gain and offset voltage of operational amplifiers. The switch-induced error voltage becomes the only major error ...

This article proposes a novel dual-stage control strategy for flying capacitor converter. During transients, the proposed scheme applies finite-control-set model predictive to drive system close desired reference, including all known nonlinearities of in converter model. When state is neighborhood controller switches pulsewidth modulation based linear with an integral action. In this case, refo...

The proposed zero-current switching switched-capacitor (ZCS SC) DC-DC converter is an innovative bi-directional power flow control conversion scheme. A zero-current switching switched-capacitor stepup/step-down bi-directional converter is presented that can improve the current stress problem during bi-directional power flow control processing. It can provide a high voltage conversion ratio of n...

Finite Control Set Model Predictive (FCS-MPC), thanks to its simple and powerful concept, has been applied widely control the multilevel converters. FCS-MPC allows of several objectives can incorporate restrictions, even nonlinear, into mathematical model system under consideration. However, needs evaluate all switching states converter find best state be in next sampling time. For higher-level...

A high step-up DC-to-DC converter that integrates an isolated transformer and a switched-clamp capacitor is presented in this study. The voltage stress of the main power switch should be clamped to 1/4 V by using the turn ratio and switched-clamp capacitor of an isolated transformer to achieve a high voltage gain. In addition, a passive clamp circuit is employed reduce voltage stress on the mai...

For battery-powered electronic products, one way to extend battery life is to use a versatile step-up/step-down DC-DC converter. A new versatile step-up/step-down switched-capacitor-based converter structure is proposed, and its efficiency is analyzed. In the step-down case, the efficiency is the same as, or even better than the efficiency of linear regulators. key words: DC-DC converter, switc...
