Hi,
1.We are facing a issue while using this configuration actually when we apply 565V DC at VDC_IN we are getting 0.1782 across R38, But as per calculation it should be 0.188 now we are getting almost 3percent less. I checked by removing R35 that time we are getting almost correct value.
2. when the VDC_IN zero the voltage across C22 we are getting 150mV but at the 6th and 7th pin of U5 is zero. Here we are using U3 TS321AILT . Finally at the out put of U3 is 600mV.
the output of U3 is going to ADC pin of microcontroller. to measure DC bus
Please help me to solve this problem.
