All electronic systems require power. However, each individual machine needs a particular type of power. If you fail to use the right power supply, you can experience a lot of problems with your electronic device. In fact, it may not even function at all. Thus, it is a good idea to learn more about the basics behind power supplies. Read on to see what you should know before using power supply circuits.
The Science Behind Conversion
Electricity starts off as AC current from an outlet in the wall. However, most devices are not designed to run directly on AC. Therefore, it becomes necessary to convert the energy before it gets to the electronics. Power supplies take AC and convert it to DC. Typically, the voltage is also reduced by an input power transformer. In some cases, the voltage may still have output variation. Regulated power supplies change this by created a DC output that is fixed. This is all very technical, but it is the main process behind the typical power supply.
The Difference Between Power Supply Units
There are actually a few different types of power supplies on the market. Regulated power supplies are more complex than the unregulated variety. In an unregulated power supply, you will notice that there is not a consistent supply of voltage to support a load. This is because they lack voltage regulators. Regulated supplies do have this feature to keep the voltage at the same level at all times.
A Look at Phase Adjustable Units
AC power supplies can be designed to use different phases. These phases include single and three level systems. A phase adjustable power source allows for the changing of frequencies and voltage. Many electronics manufacturers use these units to test their products prior to selling them in different markets.
In the End
All in all, the science behind power supplies is more complicated than you would think. However, most of us take these devices for granted on a daily basis. Before using a phase adjustable power source, it always helps to understand the basic functioning of electrical systems.
