homage ups booster circuit diagram
homage ups booster section:
The function of the homage ups booster section in inverters is to boost dc 12/24 voltage to 300-volt dc. In this pdf file, you can download the complete picture of the booster section with components and circuit diagram. I hope this diagram will help you to trace the fault in dc to dc converter section of the homage ups. after booting from the chopper a bridge rectifier is used at the output of the booster to rectify pure dc output.
how do repair the homage ups booster section?
if the dc 300 volt not generating at the dc capacitor then we confirm the fault in the booster section. First of all, we check the MOSFETs of the booster section if they are short or open then we replace and also change the booster section ic and gate resistors. In some cases, the chopper continuity will open in any spark then we repair the chopper. after repairing the section we will verify to check the resistance between the gate to source pins of booster MOSFETs, it will be the same for both groups.
