New and Used Power Supplies - AC and DC Solutions

All electronic circuits containing loads require power supplies. Some loads require AC power supplies while others are designed to run on DC supplies. Power supplies are designed to carry out multiple conversions of energy to meet the diverse demands of the different parts of the loads they drive. Systems with complicated circuitry obviously require more energy conversions than simple circuits that may have fewer parts. Different variants come as stand-alone models, while others are embedded within the loads they are supposed to drive.

From an energy source, a power supply may carry out various conversions before it feeds the various parts of a given load. A source of energy can be an energy storage device, an electromechanical system, or an energy transmission system. These energy sources may be in form of batteries, AC power source, generator, alternators, fuel cells, etc.

Loads Require Various Input Voltages

Different loads require different types of input voltages. Regulated power supplies are designed to provide a load with a constant voltage or current. Their design ensures that the output offered does not fluctuate even if the input voltage does. In contrast, the output of an unregulated power supply fluctuates whenever there are changes in the input or load needs.

In addition to the regulated and unregulated power supplies, users can opt to use an adjustable version of the regulated power supply. This power supply allows the user to program an output, and finds numerous applications due to their unique design that offers a regulated as well as adjustable output to the load.

Switching and Linear Types

Depending on the process that energy goes through before it is fed to the load, power supplies can be categorized broadly as either switching or linear types. In linear types, the direct process is carried out by a circuitry that is comprised of active components that operate in the linear region throughout the conversion process. The input of a switching power supply undergoes conversion from AC to DC, or the converse, before processing begins. This conversion is done by components that operate in the non-linear regions. Whenever active components operate in the linear region, the resulting conversion of energy to heat leads to power loss. Therefore, switching power types are considered more efficient as compared to the linear types.

A DC power supply is designed to provide a load with a fixed polarity input from a DC source or an AC one. In the case of AC source, a transformer, rectifier, and a filter are required to produce a suitable DC input to the load. A linear voltage regulator may be added if the load requires a constant voltage. On the other hand, an AC power supply provides a load with a suitable AC input from the mains supply. For a switched-mode power supply, a rectifier, switching circuitry, transformer, and filters are used to produce a regulated supply. Other types of power supplies include programmable power supply, uninterruptible power supply, and high-voltage power supply.

If looking for a suitable power supply, Test Equipment Connection has a large inventory of different types from a variety of manufacturers. We offer both new and used power supplies, and have high quality power supplies in stock.
