Introduction
A rectifier is a commonly-used device used to convert an alternating current (AC) into a direct current (DC) and it comes in a variety of forms. One of these forms is an array, which is a set of rectifiers that act together to allow a much higher power rating than the individual rectifiers within the array. STPS2545CG-TR is a rectifier array that is suitable for use in power supplies, battery chargers or any application where a higher power rating of rectification is required.
Application Fields
STPS2545CG-TR is a popular rectifier array in a wide variety of applications. The two most common applications are in power supplies, such as those used in computers and other electronic devices, and in battery chargers. The advantage of using a rectifier array is that it can provide the same amount of power as a much larger single rectifier, but it does so more efficiently and with less power loss.
Power supplies utilize rectifiers to convert incoming alternating current into direct current. This is required so that the device can use the power for its own purposes. In a power supply, the rectifier typically has a high waste factor, meaning a large amount of the power being supplied is lost as heat. By using a rectifier array, the power loss can be minimized and the efficiency of the device can be increased. Battery chargers also utilize rectifiers in order to convert incoming alternating current into a direct current, and they also benefit from the higher current ratings of rectifier arrays. The increased current ratings can provide the necessary current to rapidly charge the batteries.
Working Principle
The STPS2545CG-TR rectifier array is a four-phase rectifier array. This means that it consists of four separate diodes that are arranged in a bridge configuration. The bridge configuration allows the rectifier to convert the alternating current into a direct current. This is done by the first two sets of diodes passing the current during the positive half cycle, while the other two sets of diodes pass the current during the negative half cycle. This allows the alternating current to be converted into a direct current.
The STPS2545CG-TR rectifier array does not have automatic switching capability. This means that it will continue to pass the current even after the peak of the alternating current has passed. This can lead to a high amount of energy being wasted, as the electrical energy still being passed will be converted into heat. This is why it is important to use the correct size of rectifier array for the job in order to ensure that the correct amount of power is being delivered and that only the necessary amount of electrical energy is being wasted.
Conclusion
The STPS2545CG-TR rectifier array is a popular type of rectifier array for many different applications. It is used for power supplies and battery chargers due to its high current ratings and efficient operation. The array utilizes a four-phase bridge configuration in order to convert alternating current into a direct current. However, its lack of automatic switching results in a high amount of energy being wasted if the wrong size of rectifier array is used.
