摘要

本文提出了一种新的梯度驱动器与梯度电压逆变器，用于低功耗和小尺寸滤波电路。梯度驱动器产生具有低纹波幅度的直流电，以实现高图像质量和高转换率，以快速获得图像。该梯度驱动器的特点是由sic - mosfet组成的逆变器输出电流的纹波幅度小，而由igbt组成的另一个逆变器输出电压高。本文讨论了新型梯度驱动器的工作原理和控制方法。在全尺寸系统上进行了实验验证。计算结果表明了基于损耗分析的梯度驱动的优越性。

A proposal of a new gradient driver with a gradational voltage inverter for low power loss

This paper proposes a new gradient driver with a gradational voltage inverter for low power loss and downsized filter circuits. Gradient drivers produce direct current with low ripple amplitudes to achieve high image quality and high slew rates to obtain images rapidly. The proposed gradient driver is characterized by low ripple amplitude of the output current from the inverter composed of SiC-MOSFETs and high output voltage from another inverter composed of IGBTs. This paper discusses both the principle of operation and control method of the new gradient driver. Experimental verification is performed on a full-scale system. The results show the advantages of the proposed gradient driver based on loss analysis by calculations.
