Abstract

This paper presents an analysis and design of a charge-pump based sixth-order boost converter. The voltage gain of the converter is almost double in comparison to the conventional boost converter. Reduction in the source current ripples is primarily achieved through interleaved gating scheme. The additional capacitance (C) in the feedback path is responsible for further reduction in source current ripples. A steady-state and dynamic analysis is established to predetermine the circuit performance. This includes the current sharing on two parallel branches of the boost converter. Small-signal transfer functions are formulated to analyze the current sharing behavior during dynamical conditions. A24 to 100 V, 50 W prototype is designed for verification of source current ripples reduction and load sharing. Simulation and experimental results are presented to validate the proposed design, voltage regulation and the load division in the parallel interleaved boost-cells without using any current-mode controller. Experimental measurements are in close correlation to analytical predictions.

基于电荷泵的六阶交错升压变换器

本文介绍了一种基于电荷泵的六阶升压变换器的分析与设计。该变换器的电压增益几乎是传统升压变换器的两倍。减少源电流纹波主要是通过交错门控方案实现的。反馈路径中的附加电容(C)负责进一步减小源电流纹波。建立了稳态和动态分析，以预先确定电路的性能。这包括在升压变换器的两个并联分支上的电流共享。建立了小信号传递函数，分析了动力条件下的电流共享行为。A24至100 V, 50 W的原型设计用于验证源电流纹波减小和负载共享。仿真和实验结果验证了在不使用任何电流型控制器的情况下并联交错升压单元的设计、电压调节和负载分配。实验测量与分析预测密切相关。
