摘要
为满足感应加热电源对绝缘栅双极晶体管(Insulated Gate Bipolar Transistor,简称IGBT)驱动和保护功能的要求,采用可驱动大功率MOSFET和IGBT的IXDD414CI芯片作为主驱动元件,设计了一种驱动电路。该电路具有降栅压软关断和软关断封锁脉冲的保护功能,并能输出报警信号;其工作频率高,延迟时间小,驱动能力强,保护功能完善,因而非常适合用于大功率感应加热电源。详述了驱动电路构成和工作原理,给出了实验结果。
In order to satisfy the demand of function to drive and protect the IGBTs in the induction-heating power supply,a drive circuit is designed using the IXDD414CI made in IXYS corporation which is specifically designed to drive the largest MOSFETs and IGBTs.The circuit has the protecting functions to drop gate voltage and soft switch the IGBT, and to blockade the pulses in a soft switch, and can output a alarm signal.h has the advantages of high operation frequency, short delay time,strong drive ability and perfect protecting functions.So it is suitable for the large power induction heating power supply extremely.The principle of working, the structure of the drive circuit are described in detail, and the experimental results are given.
