Introduction

PMEG2010EV,115 is a single diode rectifier, a semiconductor device commonly used in the power industry. This article will look into its application field, working principle and its comparison with other rectifiers.

Application Field

PMEG2010EV,115 is mainly used to convert AC to DC power, thus can be used in a vast range of applications, often used in power inverters and in AC voltage regulation. This diode rectifier can produce either a single-phase or a three-phase output and is suitable for high power applications ranging from 1kW up to about 25kW.

Working Principle

Just like other diodes, PMEG2010EV,115 uses a junction between two types of semiconductor materials, p-type and n-type semiconductors, making a diode rectifier. In this case, the p-type semiconductor material is heavily doped with donor impurities, resulting in an excessive amount of free electrons and creating a negative, electron-rich terminal. Meanwhile, the n-type semiconductor material is heavily doped with acceptor impurities, resulting in an excessive amount of empty spaces and creating a positive, hole-rich terminal. By connecting a voltage source to both terminals and a load between the two, the diode rectifier can function as a traditional rectifier.

When the voltage source is connected to the diode, the electrons flow from the n-type terminal into the p-type terminal and provides power to both terminals and the load connected to them. This is known as the forward-biasing of the diode. However, when the voltage source is connected to the terminals in reverse-biasing, the electrons are pushed back, so the current stops and the power to the load and terminals is limited to zero.

Comparison to Other Rectifiers

Other rectifiers besides the diode rectifier are often used in the power industry. Three-phase rectifiers, which can handle power ratings from 30kW up to 1.2MW, are more often used for large power applications. Besides the diode rectifier, three-phase rectifiers are able to provide more power when compared to the diode rectifier, but do not have the same efficiency.

The diode rectifier is also a more cost-effective alternative to other rectifiers, as they are cheaper to build, thus making them more attractive to businesses that are looking to save money. The diode rectifier also offers reliable performance at low temperatures, making it a favorite in applications which are bound to experience low temperatures.

Conclusion

PMEG2010EV,115 is an example of a diode rectifier, a type of rectifier commonly used to convert AC to DC power. It has a low power rating and is mainly used for single-phase and three-phase outputs, and is suitable for applications where low temperatures are present. It is also a more cost-effective alternative to other rectifiers available because it is cheaper to build.
