臂板信号

This paper will emphasize on analyzing these two problems, and make a driving board with TLP250, this driving circuit can drive four IGBTs.and its driving signal is produced according to the requests, each driving signal is separated rightly with only one power supply, this circuit can also prevent from overflowing or short-circuit and keeping bridge arm from connecting directly.

本文将着重分析这两个问题，并利用TLP250设计了一块模块驱动板，此板可以驱动四个IGBT。此板的驱动信号符合要求，每路驱动信号在电位上是隔离的，而输入电源只有一个，该电路还有过流或短路保护功能以及防止桥臂直通的功能。
