摘要

本文提出了一种由两个功率级串联而成的组合升压变换器方案。第一级是一个恒占空比的两级交错升压变换器，第二级是一个变占空比的简单升压变换器。第二级电压控制器为p.i.d DC - DC升压变换器方案，在MULTISIM中实现，并在5 Ω负载下进行了数值模拟。由于变换器方案的复杂性，选择了较低的输出电流来实现合理的仿真时间。它也代表了输入电流纹波低至平均输入电流的4.16%的变换器版本。这是一个适用于燃料电池作为能源的选择。

Improved DC to DC boost converter behavior by using a two stage voltage conversion

This paper presents a combined boost converter solution which is made of two power stages in series. The first stage is a two interleaved stages boost converter with constant duty cycle and the second stage is a simple boost converter with variable duty cycle. The voltage controller of the second stage is P.I.D. DC to DC boost converter scheme was implemented in MULTISIM and numerically simulated for a load of 5 Ω. Due to the complexity of the converter scheme was chosen a lower output current to achieve a reasonable simulation time. It also stands for the version of the converter that the input current ripples are as lower as 4.16% of the average input current. This is an option that suits where a fuel cell is used as an energy source.
