变频器是用来控制一些通用型电机，例如用在风机水泵上面有很好的节能和自动控制效果，尤其是在传动控制领域的应用非常广泛，主要用在去力矩、速度、精度等要求不高的场合，是传动控制领域的重要组成部分，广泛应用于空调负载类、破碎机类负载、压缩机类负载、泵类负载、电梯高架游览车类负载等，随着市场应用的多样化需求，设计出高性价比的变频器成为重中之重。

图1 变频器电路框图

变频器主要由整流、制动、滤波、逆变、驱动单元、检测单元、控制单元等组成如上图1，中大功率的变频器一般逆变单用使用IGBT模块，而IGBT模块一般比较贵成本高，因此为了保证逆变单元的IGBT安全可靠，在设计IGBT驱动时需要选型一款带保护的隔离驱动芯片来对控制单元发出的驱动信号进行有效的强弱电隔离保护，以及保护被驱动的IGBT模块。

图2 QX330J-CuH-S 典型应用电路图

针对变频器逆变单元IGBT模块驱动设计，本文重点介绍国产群芯微电子推出的智能栅极驱动光耦QX330J-CuH-S，内置快速去饱和(DESAT) 故障检测功能、欠压锁定功能、故障反馈及自动故障重置，有源米勒钳位功能、软关断功能以及可选择的自恢复模式，兼容市场上主流的光耦及容耦隔离驱动器，为客户工程师提供安全、低成本、功能强大、抗干扰能力强的替代方案。

图3 QX33X 封装/尺寸及内部电路图

QX330J-CuH-S在变频器逆变单元驱动IGBT的典型应用电路如图2所示。正常工作时，6、7脚和8脚接收控制器的控制信号，VOUT输出驱动信号来驱动IGBT的开通和关断。当发生短路保护时候，IGBT的VCE电压通过DESAT检测，当DESAT上的电压高于6.5V时，即关掉VOUT输出并传到控制端侧并拉低FAULT, 26μs后故障自动复位，如下图4实测逻辑波形。

图4 QX330J-CuH-S 保护逻辑时序

综上所述，国产群芯微智能栅极光耦驱动器QX330J-CuH-S应用在变频器IGBT模块驱动设计，具有以下几点优势：

1、最大1.5A输出峰值电流，可以驱动逆变单元1200/150A规格的IGBT，驱动能力强；

2、管脚定义及封装为图3所示，其封装为SOIC16宽体，并提供大于8mm的爬电和间隙距离；

3、高共模瞬态抑制CMTI可高达50kV/μs，具有更强的抗干扰性，可提高了整体产品的可靠性;

4、具有更好的动态特性，传播延迟最大250ns、脉冲宽度失真最大100ns，延时和失真都明显小，可以减少死区时间，提高产品的性能；

5、更高的安全性，具有快速去饱和(DESAT) 故障检测功能、欠压锁定功能、故障反馈及自动故障重置，有源米勒钳位功能、软关断功能等保护功能加持，使发生短路过流时保护电路和人员安全。
