摘要

随着高速电子器件的发展，大功率变换器的设计也发生了相应的变化，主要体现在速度、尺寸、可靠性和效率等方面。本文提出了二电平DC-DC升压变换器的硬件实现。该系统采用12V - 48V升压变换器和灯负载，采用dSPACE 1104控制器。传统的DC-DC变换器存在工作在高占空比、高开关电压应力和高二极管峰值电流的缺点。两电平DC-DC升压变换器的主要优点是连续输入电流，无变压器，允许高开关频率，无需修改主电路即可增加更多电平。通过不同占空比下的仿真结果和硬件结果的比较，对两电平DC-DC升压变换器进行了验证。

12/48V two level DC-DC boost converter using DSPACE

The development of high speed electronic devices tends to relevant changes in the designing of the converters for power applications mainly on the speed, size, reliability and efficiency. This paper proposes the hardware implementation of two level DC-DC boost converter. The proposed system has 12V - 48V boost converter with lamp loads by using dSPACE 1104 controller. Conventional DC-DC converters have the disadvantages of operating at high duty cycle, high switch voltage stress and high diode peak current. The major advantage of two level DC-DC boost converter are continuous input current, transformerless which allows high switching frequency and more levels can be added without modifying the main circuit. The two level DC-DC boost converter is validated by comparing simulation and hardware results under different duty ratio.
