A power supply is an electrical device that converts the electric current that comes in from a power source, such as the power mains, to the voltage and current values necessary for powering a load, such as a motor or electronic device.
The objective of a power supply is to power the load with the proper voltage and current. The current must be supplied in a controlled manner — and with an accurate voltage — to a wide range of loads, sometimes simultaneously, all without letting changes in the input voltage or in other connected devices affect the output. A power supply can be external, often seen in devices such as laptops and phone chargers, or internal, such as in larger devices such as desktop computers. A power supply can either be regulated or unregulated.
In a regulated power supply, the changes in the input voltage do not affect the output. On the other hand, in an unregulated power supply, the output depends on any changes in the input. The one thing all power supplies have in common is that they take electric power from the source at the input, transform it in some way, and deliver it to the load at the output. The power at the input and output can be either alternating current AC or direct current DC :.
The first step in any power supply design is to determine the input current. The typical waveform for an alternating current is a sine wave see Figure 1. There are several indicators that must be taken into account when working with an AC power supply:.
Alternating current AC is the way electric power is transmitted from generating facilities to end users. It is used for power transportation because electricity needs to be transformed several times during the transportation process. Electric generators produce voltages of about 40,V, or 40kV. This voltage is then stepped up to anywhere between kV and kV, to reduce power losses when transporting electric current over long distances.
Once it reaches its destination area, the voltage is stepped down to between 4kV and 35kV. Finally, before the current reaches individual users, it is reduced to V or V, depending on the location. All these changes in voltage would be either complicated or very inefficient to do with direct current DC , because linear transformers depend on voltage fluctuation to transfer and transform electrical energy, so they can only work with alternating current AC.
By using a transformer, the alternating current AC input voltage is reduced to a value more suitable for the intended application. Then, the reduced AC voltage is rectified and turned into a direct current DC voltage, which is filtered in order to further improve the waveform quality Figure 2. Because the input voltage is transformed at the input, the necessary transformer would have to be very large and therefore very heavy. At low frequencies e. This demands large transformer cores, which makes miniaturization of these power supplies practically impossible.
These linear regulators dissipate any extra energy in the form of heat. For low power, does not pose much of a problem. However, for high power, the heat that a regulator would have to dissipate to maintain a constant output voltage is very high, and would require adding extremely large heatsinks. Switching power supplies are now possible thanks to the evolution of semiconductor technology, especially thanks to the creation of high-power MOSFET transistors, which can switch on and off very quickly and efficiently, even if large voltages and currents are present.
In switching AC power supplies, the input voltage is no longer reduced; rather, it is rectified and filtered at the input. Then the DC voltage goes through a chopper, which converts the voltage into a high-frequency pulse train. Finally, the wave goes through another rectifier and filter, which converts it back to direct current DC and eliminates any remaining alternating current AC component that may be present before reaching the output see Figure 3. As could be expected, this new design method does have some drawbacks.
This creates a need for more complex control circuitry, which in turn adds complexity to the design. Nevertheless, these filters are made up of components that can be easily integrated, so it does not affect the size of the power supply significantly. An alternating current AC power supply can either be single-phase or three-phase:. The main difference between these two configurations is the ability to add a neutral wire see Figure 5. Delta connections offer greater reliability, but Y connections can supply two different voltages: phase voltage, which is the single-phase voltage supplied to homes, and line voltage, for powering larger loads.
Because a standard power distribution system must supply power to both three-phase and single-phase systems, most power distribution networks have three lines and a neutral.
This way, both homes and industrial machinery can be supplied with the same transmission line. Therefore, the Y configuration is the most commonly used for power distribution, whereas the delta configuration is typically used to power three-phase loads, such as large electric motors. The voltage at which the power grid delivers single-phase electric power to its users has various values, depending on the geographical location. Otherwise, you could damage the power supply or the device connected to it.
Table 2 compares the grid voltages in different areas around the world. In the western city of Osaka, electricity suppliers bought 60Hz generators from the United States, while in Tokyo, which is in the east of Japan, they bought 50Hz German generators. Both sides refused to change their frequency, and to this day Japan still has two frequencies: 50Hz in the east, 60Hz in the west.
As mentioned before, three-phase power is not only used for transportation, but is also used to power large loads, such as electric motors or charging large batteries. This is because the parallel application of power in three-phase systems can transfer much more energy to a load, and can do so more evenly, due to the overlapping of the three phases see Figure 6. For example, when charging an electric vehicle EV , the amount of power you can transfer to the battery determines how fast it charges.
These chargers, are limited in power by the grid and the AC socket. On the other hand, three-phase power supplies convert the power from AC to DC externally, and can transfer over kW to the battery, enabling super-fast charging. Alternating current is used to transport electric power all across the electric grid, from generators to end users. An alternating current AC circuit can be configured as a single-phase or a three-phase system.
Single-phase systems are simpler, and can deliver enough power to supply an entire house, but three-phase systems can deliver much more power in a more stable way, which is why they are frequently used to supply power for industrial applications. By contrast, switching power supplies have become extremely popular, because they use switching regulators to convert AC to DC power.

Latest activity 15 hours ago. Hi, evaluating the above for use on advanced lighting controller. Large transformers are necessary, adding substantial size and weight. Higher frequencies allow for much smaller transformers, if needed. If unregulated, transformer losses are the only significant causes for efficiency loss.
If regulated, high power applications will have a critical effect on efficiency. Transistors offer small switching losses, because they behave as small resistances. This enables efficient high-power applications. Unregulated power supplies may have significant noise caused by the voltage ripple, but regulated linear AC DC power supplies can have extremely low noise.
That is why they are used in medical sensing applications. When transistors switch very quickly, they generate noise in the circuit. However, this can be either filtered out, or the switching frequency can be made extremely high, above the limit of human hearing, for audio applications. The added noise generated by the transformers forces the addition of large, complex filters, as well as control and regulation circuitry for the converters.

Note: The wiring of 48V inverter is similar to the 24V inverter, and the batteries are connected in series. First of all, it need to consider efficiency of conversion. Because the inverter itself has a certain power consumption characteristics, part of the current will be always lost when DC is inverted to AC. Therefore, the high or low efficiency of conversion in this process has also become one of the standards that power inverter is good or bad.
