功率驱动集成电路安全性分析与设计

Security of Analysis and Design of Power Drive IC

功率驱动电路是控制电路和功率放大器的联接纽带。功率放大器多数选择相应的功率电路形式(三相全桥或H桥等)以及主功率器件,而对于功率驱动电路设计,则是电路安全工作的核心,特别是对于中、大功率控制器设计。文中先抛开电路布线安全性设计,主要介绍驱动集成电路原理安全性设计。

The power drive circuit is the joint link between the control circuit and the power amplifier. The design regarding the power amplifier is relatively simple in the circuit. We usually only select the power circuit form （ three-phase entire bridge or the H bridge and so on） and the type of power components. But the design regarding drive circuit, especially regarding middle/high power＇s, is the core question. The paper, first abandoning the PCB wiring＇s secure design, mainly introduced the drive ICs＇ principle secure design.
