Saves The Investment For Adapter

What is the constant power rectifier technology?

Power adapter rectifier is the most important part of the power supply system, whether it is technologically advanced or not, relates to the function and reliability of the power adapter system.Therefore, as a manufacturer, Eahunt pays great attention to the improvement of the technical performance of the power adapter rectifier, which aims to make the reliability and efficiency of the power adapter rectifier greatly improved, and to make the cost and the high-frequency electromagnetic interference reduced.

Constant power rectifier, its outstanding feature is in the specified AC input voltage and DC output voltage range can give a fixed power. this new intelligent high-frequency power adapter system using constant power design, is a power adapter conceptualization of a leap, but also the optimal choice of modern power adapter equipment.

In the ordinary current-limited rectifier, its output characteristics can be divided into two categories, namely, constant-current and constant-voltage characteristics. in the constant-current ordinary current-limited rectifier, its output current remains unchanged; in the constant-voltage ordinary current-limited rectifier, its output voltage remains unchanged. in the constant-current ordinary current-limited rectifier, if the load current exceeds the value of the current limitation, then the rectifier output voltage will be increased with the current and the rapid decline until the rectifier overcurrent and shut down. The rated current, limited current and overcurrent values are very close to each other.

The difference between a constant power rectifier and a current-limited rectifier is that a constant power stage is inserted into the constant voltage and constant current stages, which is called a constant power rectifier. the rectifier operates in three different output stages, i.e., constant voltage, constant power, and constant current stages. the operation of the constant voltage and constant current stages is exactly the same as that of a current-limited rectifier, with the difference that in the constant power stage, the output power of the rectifier is kept constant.

Therefore, the use of constant power rectifier design of the power adapter system, generally only need to consider the maximum load of electronic equipment and rectifier redundancy, you can determine the rated output power of the power supply system, which compared with the use of current-limiting power adapter system, the required rectifier power and the number of rectifier modules can be reduced by at least 33% or more, which also greatly saves the investment.

Now the electronics industry unprecedented prosperity, many companies are researching and developing the production of a variety of electrical products, of course, in these electrical appliances officially put into the market, but also a source manufacturer specializing in the manufacture of power supply to customize the power adapter.
