the Power Supply Module 's Withstand Voltage Capability

Analysis and Solution of the Power Supply Module 's Withstand Voltage Capability The Analysis:The withstand voltage value of Isolated power modules(DC/DC converters,AC/DC converters) is up to thousands of VDC,But in the application circuit, what factors will greatly reduce the Withstand Voltage capacity? 1. by the Voltage tester has a boot overshoot;2. The withstand voltage value of the Power mdoules selected is not enough3. Using reflow, hot air gun several times while Repair.Here is the circuit of Volatge test:                                               The Solution:1.voltage gradually increasing while test;2.select higher withstand voltage value Power mdoules3. Choose the proper temperature When welding the power supply module, avoid repeated welding and damaged the power module.*There are a wide range of power module failure problems, above tips only for reference.any questions, welcome contact TOPPOWER team at sales2@gztoppower.comTOPPOWER is a leading manufacturer of power converters :  0.1W-40W DCDC converter & 3W-30W ACDC converters.
