摘　　要：基于DSP TMS320F28335的三相逆变器采用空间矢量脉宽调制技术(SVPWM)对逆变桥电路进行控制,在逆变过程中,为确保系统的稳定性及可靠性,该系统在驱动信号传输过程中采用差分信号双绞线传输方式,提高了信号的传送距离。逆变桥臂保护则采用了带过流保护功能的栅极驱动器光耦HCPL-316J进行隔离保护,带自保护功能,能够有效防止开关管短路造成器件损伤。Based on DSP TMS320F28335, three-phase inverter used space vector pulse width modulation （SVPWM） to control the inverter bridge circuit. In the inverter process, in order to ensure system stability and reliability of the system during the drive signal transmission procession using differential signal twisted pair line transmission mode, improved signal transmission distance. Inverter bridge arm protection used the gate drive optocoupler HCPL 316J with overcurrent protec- tion function to isolation protection. With self-protection function, it can effectively prevent device damages caused by switching short circuit.
