Please let me know that why components in primary side in SMPS battery charger damaged i.e bridge rectifier diodes, switching transistor 10N60, current sense resistor 0.5 ohms, optocoupler and UC3842 at the same time.
What would be a reason behind this failure I repaired three times but same thing occured?
