I plan to use ADP1047/8 with a 3 Phases AC input.
If the passive rectifier output not reach the zero voltage, is that the product will work ?
Does ADO1047 have any loading concern ?
I setup 0.1ms to load ADP1047 I2C , It will shuntdown until the time up to 250ms !!
Anything I miss ?
There are some questions about the ADP1047/1048. Please kindly help advise.
1. There are two OT fault flags in the Flag setting in GUI. What differennce between them?
2. If the RTD pin direct connect to GND, whether it has no OTP…
請問 ~ ADP1047 300W evb , 我測試到THD非常高在30W的時候 ~ 大約THD落在50左右
這樣是正常的嗎 ? 有人說內建的設定檔案是有誤的? 還是誰有正確版的可以分享一下 ?
im looking for a pfc for a new application
input voltage: 380Vac to 440Vac 50Hz.
output voltage: 700V. 750V is possible too.
output power 2KW.
switching freq: 200Khz.
we dont want to use interleave solution.
the main demand is PF>0.99 and THD<3…
could the ADP1047 be used for DC/DC design? I want to design a SEPIC controller like this one:
The requirements are as follows:
I'm working on a PFC input stage built around an ADP1047. The input is 230 volt 50 Hz, the output 385 volt DC and the maximum power
is supposed to reach 2100 Watt.
It's working quite nicely up to a power level of about 800 Watt. If the load…
I am testing ADP1047 EVB and the ADP1047 output connect to a DC to DC.(Phase-shift).
Now I find out that the Communication is very easy to lost when the DC to DC stage turn on.
Is there any way to avoid the GUI to lost the communication with ADP1047…
I now try to operate and test ADP1047 300W Evaluation Kit (ADP1047-300-EVALZ), PRD-1334 V1.3 document Page2 VIN Typ. 115 or 230, Efficiency@95%, but this document not have any Efficiency test waveform can you to provide this information…
I have the following questions.
0xFE20 - Voltage loop filter gain
0xFE21 - Voltage loop filter zero
0xFE22 - Fast voltage loop filter gain
0xFE23 - Fast voltage loop filter zero
For the above mentioned register’s, I am able to read…
