基于IR2136与MOSFET的无刷直流电机驱动电路设计
资料介绍
针对传统驱动电路的设计,需要采用相互独立的电源为功率开关管供电,使得硬件结构复杂,可靠性下降,为此,基于功率驱动芯片IR2136与场效应管MOSFET,从信号隔离、三相逆变驱动、过流保护电路等方面,对无刷直流电机驱动电路进行设计。重点阐述了三相逆变驱动电路中的自举电路设计和功率管的驱动保护优化设计。采用TMS570控制板,对该驱动电路进行功能测试,结果表明,设计的驱动电路能够驱动电机平稳运行,且工作稳定可靠。
The independent power supplies are adopted to supply power for the power switch tube in the traditional drive circuit design,which makes hardware structure complex and reliability reduced.Therefore,a drive circuit based on the power drive chip IR2136 and field-effect tube MOSFET is designed for the brushless DC motor from the respects of signal isolation,three-phase inverter drive,and overcurrent protection circuit.The design of the bootstrap circuit and optimization design for drive protection of the power tube in the three-phase inverter drive circuit are expounded emphatically.The TMS570 control board is used to perform functional test of the drive circuit.The results show that the designed drive circuit can drive the motor to operate smoothly,stably and reliably.
