Abstract

The parallelling of power semiconductor devices is essential for desired current ratings and the system is prone to the current unbalancing due to parameter variations. SiC devices with significant variable threshold voltage due to manufacturing yield and temperature distribution have a consequential possibility of dynamic current unbalancing. This paper presents the peak detection-based current balancing of parallel-connected SiC devices to minimize the turn-on and turn-off current unbalancing. PCB current sensors are used for the measurement and feedback of the signal for this peak detection-based current balancing mechanism.

利用PCB传感器进行峰值检测的并联碳化硅（SiC） MOSFET功率器件的电流平衡

功率半导体器件的并联对于期望的额定电流是必不可少的，系统容易由于参数的变化而产生电流不平衡。由于制造成品率和温度分布的影响，阈值电压变化较大的SiC器件有可能产生动态电流不平衡。本文提出了一种基于峰值检测的并联SiC器件的电流平衡方法，以减小通断电流不平衡。这种基于峰值检测的电流平衡机制使用PCB电流传感器对信号进行测量和反馈。

期刊介绍： Microelectronics Reliability, is dedicated to disseminating the latest research results and related information on the reliability of microelectronic devices, circuits and systems, from materials, process and manufacturing, to design, testing and operation. The coverage of the journal includes the following topics: measurement, understanding and analysis; evaluation and prediction; modelling and simulation; methodologies and mitigation. Papers which combine reliability with other important areas of microelectronics engineering, such as design, fabrication, integration, testing, and field operation will also be welcome, and practical papers reporting case studies in the field and specific application domains are particularly encouraged. Most accepted papers will be published as Research Papers, describing significant advances and completed work. Papers reviewing important developing topics of general interest may be accepted for publication as Review Papers. Urgent communications of a more preliminary nature and short reports on completed practical work of current interest may be considered for publication as Research Notes. All contributions are subject to peer review by leading experts in the field.
