TIDA-01606: 請教一個關於量測的問題

Part Number: TIDA-01606
Other Parts Discussed in Thread: C2000WARE,

1. 我們在使用lab2時發現TINV_vBus_sensed_Volts的電壓會偏高

另外3相TINV_vGrid_A_sensed_Volts TINV_vGrid_B_sensed_Volts TINV_vGrid_C_sensed_Volts 的電壓會偏低?

這個可以調整嗎?

2. #define TINV_ADC_PU_SCALE_FACTOR        ((float32_t)0.000244140625)

這個是以1.0v為vref ? 可是控制卡不是3.0 v嗎?

3. 在測試lab5時,如果輸入頻率大於65,就會量測不到電壓電流?這個可以調整嗎?

感謝你的幫忙:D
