驱动电路、驱动模块以及电机驱动装置
摘要：
提供了一种驱动电路、驱动模块以及电机驱动装置，其能够调节用于驱动功率半导体器件的驱动电流。该驱动电路包括：驱动单元，包括多个驱动器，根据选择信号在多个驱动器中选择相应的驱动器以确定用于驱动半导体器件的驱动信号的电流水平；定时控制单元，检测传送至半导体器件的驱动信号的相移时间以及将所检测的时间与预设参考时间进行比较以控制驱动信号的相移时间；以及驱动控制单元，根据来自外部的控制信号和定时控制单元的定时控制信号，提供用于在驱动单元的多个驱动器中选择被驱动的驱动器的选择信号。
摘要（英）：

There are provided a driving circuit, a driving module, a motor driving apparatus capable of adjusting a driving current driving a power semiconductor device, the driving circuit including a driving unit including a plurality of drivers and selecting a corresponding driver among the plurality of drivers according to a selection signal to determine a current level of a driving signal for driving a semiconductor device, a timing controlling unit detecting a phase shift time of the driving signal transferred to the semiconductor device and comparing the detected time with a preset reference time to control the phase shift time of the driving signal, and a driving controlling unit providing the selection signal for selecting a driver to be driven among the plurality of drivers of the driving unit according a control signal from the outside and a timing control signal of the timing controlling unit.
