Transformerless Power Supply Circuit Design
Transformerless Power Supply Circuit Design / Voltage Dropper Circuit. How to design Transformerless Power Supply circuit Explained with Calculation. how to convert ac to dc power supply without transformer, convert 220v to 12v Dc power supply using polyester capacitor, without transformer
capacitor dropper circuit is an un-isolated, low output current power supply which drops the line voltage using capacitive reactance. at the output of dropper circuit a bridge rectifier is used to convert ac voltage in dc voltage, then a polar capacitor and a zener diode is connected at output of bridge rectifier. i explained the calculations with practical circuit design and its analysis with circuit diagram. i explained the working principle and functional description using schematic and practical circuit design. we can also use LM7805, 7808, 7809, 7812 or 7815 voltage regulators to get regulated output
to calculate a transformerless power supply circuit we need to calculate the capacitance for capacitor dropper. for calculation we need to determine the line frequency and using XC capacitive reactance formula we can know the polyester film capacitor in 400 v range
how to make transformerless ac to dc power supply
we can make 220v ac to 5v dc 12v DC but the output current is normally in milliamperes.
transformerless power supply is much cheaper than any ac to dc switch mode converter circuit. capacitor dropper dc power supply is used to power up very low current consuming circuits
