PMEG2015EV,115

Diode rectifiers, particularly single diodes, are a common element found in a number of applications due to their sheer simplicity and low cost of implementation. PMEG2015EV is a single diode that adheres to industry standards in terms of size, voltage, power and current ratings, being especially useful for its use in power line and DC applications. This article will provide an overview of the application fields and working principle of the PMEG2015EV rectifier.

Application Fields

The principal applications of the PMEG2015EV rectifier include power line, DC power, and low voltage applications. It is typically used for rectification of alternating current in power line applications, allowing AC to be converted to DC power. In DC power applications, the PMEG2015EV can be used to reverse the potential of a current, as well as reduce voltage. Furthermore, it is commonly used in low voltage applications such as lighting, backlighting, and automotive systems where the rectifier preserves the original design and contributes to energy efficiency, stability, and reliability.

Working Principle

At its simplest level, a rectifier is an electronic component that allows current to flow in one direction only. Single diode rectifiers such as the PMEG2015EV can work with any one of a number of different basic circuits, some of which are shown below:

In the first circuit, the most basic, the diode acts as a switch: when there is a reverse bias (or non-conductive) between the anode and the cathode the current is prevented from flowing due the inability of the circuit to reach a thermal equilibrium. When the bias changes state, the diode begins to conduct, allowing current to flow from the anode to the cathode. The same concept applies in the second, third and fourth circuits (known as bridge circuits) although the output current is slightly modified. In the fifth circuit, the diode is used to restrict the AC input current to one direction, producing a DC signal to perform signal rectification of the AC input.

Conclusion

In summary, the PMEG2015EV single diode rectifier is used in power line, DC power, and low voltage applications, and is capable of working with various basic circuit arrangements. Its small size, low cost and ease of implementation lend it well to a range of applications, and its capacity to restrict current to one direction means it is suitable for signal rectification as well.
