This paper considers the design and evaluation of transformer-based and transformer less-based variable regulated dc power supply with the aim of presenting a comparative analysis between them and their respective areas of applications the quality, cost, size, weight, performance and efficient production of dc power supply thus pose a great deal of concern and attention in the dc power. We can convert the high voltage ac into low voltage such as 5v, 6v, 9v, 12v dc, without using the transformer, which is called transformerless power supply here is the circuit diagram and explanation for transformerless power supply. A regulated power supply is one that controls the output voltage or current to a specific value the controlled value is held nearly constant despite variations in either load current or the voltage supplied by the power supply's energy source. Question 3 an essential part of an ac-dc power supply circuit is the ﬁlter, used to separate the residual ac (called the ”ripple” voltage) from the dc voltage prior to output.
