Dear Easy-peasy I`ve check every resistor on that PCB and nothing was wrong.For the most part, I traced the control loop and found that one Opamp held in the control board would be the problem and changing it didn`t do anything. I doubt that I even find the problem correctly , maybe somewhere...
Hi , the problem has changed and the voltage is stabled now in rage of 800 to 850 but I think it should be below 780 and the protection circuit and Uc diagnose this as a major problem and the Uc doesn`t start the inverter and UPS starts buzzing continuously.
Hi , I`ve faced many converters having one issue . They properly work for some seconds and then the output voltage suddenly increases and if i didn`t turn them off the output DC link would be blown. Take a push-pull DC/DC converter as an example , more specifically I have been working on a MGE...
