Capacitor dropper or transformer less power supply is used for low power and cheap electronic devices
Transformer less power supply consists 5 blocks:
1-Series resistor ; which is used to prevent the capacitor from high or boulki current.
2-Capacitor : is use to minimize the supply voltages according to the load requirement .
NOTE:::the capacitor which is used for voltage doper , should be no polar and 1 resistor which have the resistance or 1M ohm should be placed in parallel with the capacitor .
3-Rectifier unit: : is used to convert ac voltages into dc voltages .
4- Filter unit: is used to minimize the ripple at the output ot the rectifier unit.
5-Regulator unit :: is used to fix the voltagelevel according to the load requirement . .
if u have any doubt about this explanation so, plz
