Transformerless Power Supply


One of the major problems that is to be solved in an electronic circuit design is the production of low voltage DC power supply from AC to power the circuit. The conventional method is the use of a step-down transformer to reduce the 230 V AC to a desired level of low voltage AC. The most suitable and low cost method is the use of a Voltage Dropping Capacitor in series with the phase line.
