As the name defines, a transformerless power supply circuit provides a low DC from the mains high voltage AC, without using any form of transformer or inductor. It works by using a high voltage capacitor to drop the mains AC current to the required lower level which may be suitable for the connected electronic circuit or load.

Any DC-DC Converter takes a DC source from a mains powered power supply or a battery or battery bank and converts that to a regulated supply (for example, 5V +/- 0.001V).
AC/DC supplies are easy to fit multiple outputs around a transformer from a single input that then gets regulated. DC on the other hand is a bit more work and I wouldn''t expect a similar rated supply to fit in the same space. The reasons for that are mainly in the realms of electronics, but generally DC/DC supplies need an input, buck/boost

For a given circuit, in my case, the toy, the resistance R is a constant. If I replace my batteries with a power supply of equal voltage, then the current in the system also stays the same. This project uses this relationship to replace Voltage, V supplied by a battery with voltage supplied by a DC power supply – nothing else is changed.

The UPS01 Uninterrupted Power Supply efficiently converts AC 100-240V to DC 24V, and provides 150 W continuous output power and 180 W of peak power. High quality chip with wide range of input voltage, the UPS01 adapter is popularly used among customers. With AC plug & play design, this power supply can directly power all the DC 24V devices.
AC power allows the variation of voltage levels via a transformer, unfortunately this doesn't work with DC power. Sometimes it is necessary to convert the power, for example, from a 24V truck battery to 12V in order to power a car radio. So it's necessary to use a converter to drop the power and make it safe for the device.
There are still some that are not solid state due to their high-power outputs (for example, Railway Sub-stations that power sections of lines). Any DC-DC Converter takes a DC source from a mains powered power supply or a battery or battery bank and converts that to a regulated supply (for example, 5V +/- 0.001V).
As the name implies a DC-DC converter is an electronic circuit or electromechanical device which takes a source of direct current (DC) and converts it from one voltage level to another. They are used where the operating voltage for some electronic devices vary making it necessary to provide a separate voltage for each device.
Works in excessively heat, cold and humid environment. The UPS01 power supply can directly offer power to all the DC 24V devices, such as gate openers, CCTV security cameras, LED strip lights, mechanical arms, door access control system and other DIY tools.
Types of DC-DC converters include: Isolated DC-DC converters - in these the output is isolated from the input with internal transformers to convert the input to a different output voltage. They have higher isolation voltage properties and unlike the non-isolated version have the ability to block noise and interference.
