【选型】国产栅极驱动光耦QX350-CUH-D用于光伏逆变器，最小峰值输出电流达2.5A

时间： 2022-05-08 来源：世强

技术问答

逆变器是在太阳能发电系统中，由直流低电压转换成正弦波220V家用交流电压或并入电网的交流高电压的设备。逆变器上需要用到晶体管光耦、高速光耦、栅极驱动光耦、智能栅极驱动光耦、光隔离运算放大器等隔离器件。某客户在预研一款逆变器，输出端需求一款栅极驱动光耦，之前采用的是东芝的方案TLP350，客户要求输出电流至少2.5A用来驱动IGBT；本文推荐国产品牌群芯微的栅极驱动光耦QX350-CUH-D。如下图一为逆变器DC-DC-AC转换电路图。

图一逆变器DC-DC-AC转换电路图

逆变器DC-DC-AC转换电路图由功率转换部分、控制部分和电流检测部分组成。光伏电池板上的直流低压经过BOOST升压、滤波和IGBT逆变输出交流电。主控DSP发出PWM波形来控制栅极驱动光耦进而控制IGBT的导通和关断，并通过电流检测来反馈电流输出信号。国产品牌群芯微的栅极驱动光耦QX350-CUH-D在电机控制逆变器、光伏逆变器和UPS等大功率产品上有大量成功应用案例；QX350-CUH-D最小峰值输出电流达2.5A，驱动能力强，并且带滞后欠压锁定(UVLO)功能，能保证IGBT在欠压状态时的有效关断；它的工作温度范围从-40℃至110℃，满足工业应用场合要求。

群芯微栅极驱动光耦产品性能稳定可靠，品质保证，交期较好。

1、通过可靠性测试：可靠性实验室针对各产品进行1000h可靠性验证；

2、高温测试：85℃高温测试，各批次针对高温环境下的性能及封装质量进行验证；

3、高压测试：6kV RMS高压测试，爬电及击穿电压均高于业界常规器件；

4、X-RAY检验：X-RAY设备每批检验打线及上芯情况，出货前检验成品；

5、视觉系统外观检测：测试后通过视觉外观检验确认芯片外观、印字、引脚符合品质需求；

6、视觉系统点胶检测：点胶后通过视觉系统检验保证点胶质量，防止漏点胶产品漏出。
