But for testing, even this is not a hard and fast rule and a carbon resistor should work just fine. There is absolutely no imaginable reason not to use an isolation transformer for troubleshooting SMPSs except possibly for the final test where confirmation is needed that the inrush from a direct line connection (which will have virtually unlimited instantaneous current capability) will not damage the newly repaired supply. Printers, fax machines, copiers. Otherwise it will be wise to check the voltages on the mains side as well (Steps 3 to 5). This time, the temperature slowly rose to about 115 degrees and stayed there. Initial post-repair testing Once defective parts have been replaced, if possible remove the normal load from the supply if you have not already done so just in case it decides to put excessive voltage on its outputs and replace with a dummy load. Some supplies use small transformers for feedback rather than optoisolators. Repairing that was an entertainment. The controller is typically a TI TL494 that operates off the output of the supply. These may look like normal axial lead diodes or may be combined in pairs inside TO220 type packages.

--- Sam.) SMPS usually try to regulate one of the output voltages by using the switcher, usually it's the output with the most power, but might be the one that's most voltage critical. If the manufacturer didn't include this feature, there may be a good reason! The supply is clearly marked as being autoswitching or having universal power input. Thanks Dell. The power transformer is itself, self oscillating. Whenthe switch turns off, the voltage across L1 reverses, same technology but having either a higher current rating Philips Semiconductors Switch Mode Technology . Otherwise you have to restart your investigation of the small transformer/one power transistor part of the circuit. All Rights Reserved.
