使用TI光伏逆变器时,上电有糊味,希望解答!谢谢!

Other Parts Discussed in Thread: CONTROLSUITE, TMDSCNCDH52C1

TI工程师您好!

我使用的器件型号是High Voltage Single Phase Inverter Development Kit。下载好程序(已经显示running状态),程序是controlSUITE中自带的光伏逆变程序。我逐渐上电到100V左右的时候,就有比较明显的糊味出现,以至于接下来不敢上电。上电到几十V 的时候开发板上LD2与LD3交替闪烁,应该处于待机状态。请问,我这是出现了什么问题?我的调剂步骤如下(是TI官方自带),接线图也如下所示。谢谢!
