采用MOSFET作为功率器件,设计实现了针对横向磁通电机的功率驱动电路.该电路采用光耦HC鄄PL4504和专用驱动芯片UCC27321,具有外围电路简单可靠的特点;同时,为了抑制MOSFET两端出现的电压尖峰,设计了RCD缓冲电路.详细阐述了横向磁通电机驱动方案的整体结构、驱动电路设计以及关键参数的计算流程.最后,开展了900W横向磁通电机驱动电路及缓冲电路的实验测试工作,通过试验测试验证所设计的驱动电路及缓冲电路的实用性和有效性.

Based on the opto- coupler HCPL4504 and the integrated chip UCC27321,a power drive circuit was designed for a transverse flux motor using MOSFET as power devices. The design has simple and reliable peripheral circuit.The RCD snubber circuits was also designed to suppress voltage spikes across the MOSFET. Then,the overall structure,drive circuit design and key parameters' determination was described in detail. The experimental testing of suggested drive circuit and snubber circuits was accomplished to verify their practicality and effectiveness for a transverse flux motor with rated power of 900 W.
