3P25U3H/36

The 3P25U3H/36 is a 36-pulse controlled rectifier used to support many different types of applications. This type of rectifier is capable of regulating voltage to a specified level with steady current output, making it an ideal choice when accuracy is a necessity. This article will cover the various areas of application and the underlying working principle of the 3P25U3H/36.

Initially developed for the commercial and industrial sectors, 3P25U3H/36 is now also becoming popular with automotive and aerospace industries. In commercial and industrial applications, the rectifier is mainly used in applications such as UPSs, power conversion, AC/DC drives, traction systems, welding power supplies, aerospace and medical applications. As for automotive applications, the rectifier is mainly used in hybrid electric vehicles and fuel cells.

In general, the 3P25U3H/36 rectifier consists of six distinctive functions: AC-to-DC power conversion, rectification, filtering, regulation, surge protection, and inversion. The rectifier utilizes three-phase induction technology and its six function operates independently of each other, providing excellent load dynamic response, wide range of adjustable parameters, low ripple output, and great protection while operating under excessively high and low temperatures.

In order to perform the six functions of the 3P25U3H/36 rectifier, the circuit utilizes a three-phase bridge topology. This bridge topology consists of two diode bridges arranged in a full-wave rectification configuration. The three-phase bridge rectifier is capable of converting the incoming three-phase AC signal into a DC voltage waveform. Once the signal is converted, it is then sent to the output busbar which is connected to the filter after passing through a surge suppression component. Having undergone the filtering process, the signal can then be applied to the appropriate load.

The 3P25U3H/36 also has an adjustable regulator, allowing the user to precisely adjust the output voltage. This can be achieved by slowly changing the conduction angle of the rectifier and thus obtaining a regulated DC output voltage. Furthermore, the 3P25U3H/36 offers improved protection in both overvoltage and undervoltage conditions. The overvoltage circuit is designed to disconnect the rectifier from the AC power supply should an excessively high voltage occur, while the undervoltage circuit prevents the output voltage from falling beneath a certain threshold.

In conclusion, the 3P25U3H/36 is a versatile rectifier suitable for multiple applications. It can be used in the commercial and industrial sector, the automotive and aerospace sector, and many other areas where precise voltage regulation is important. The rectifier’s working principle is based on the three-phase bridge topology which converts the AC input signal into DC output and is then further regulated by the adjustable regulator. Moreover, the rectifier is also designed with additional protection circuits to provide safety in cases of excessive overvoltage and undervoltage.
