一种基于GaN功率器件的超高速主轴控制器
摘要：
本发明涉及一种基于GaN功率器件的超高速主轴控制器，其包括第一AC/DC电源转换电路、母线制动电路、第二AC/DC电源转换电路、功率控制模块和主控制模块；所述第一AC/DC电源转换电路和第二AC/DC电源转换电路分别将外部输入交流AC转换为DC功率部分及DC24V控制部分的直流电；所述DC24V控制部分的直流电输入所述主控制模块；所述DC功率部分的直流电经所述母线制动电路后输入所述功率控制模块，所述功率控制模块与所述主控制模块进行信息交互，由所述功率控制模块控制电机的高速主轴工作状态。本发明提高了逆变器的开关频率，并实现了单周期控制的目的，从而提高整体系统的稳定性。
摘要（英）：

The invention relates to a GaN power device-based super high speed spindle controller, which comprises a first AC/DC power conversion circuit, a bus brake circuit, a second AC/DC power conversion circuit, a power control module and a main control module, wherein the first AC/DC power conversion circuit and the second AC/DC power conversion circuit convert external input AC to DC of a DC power partand a DC 24V control part; the DC of the DC 24V control part is inputted to the main control module; the DC of the DC power part passes through the bus brake circuit and is then inputted to the powercontrol module; the power control module and the main control module perform information interaction; and the working state of the high speed spindle of the motor is controlled by the power control module. The switching frequency of an inverter is improved, the purpose of single period control is realized, and the stability of the whole system is further improved.
