Diodes - Bridge Rectifiers are essentially comprised of four diodes configured in a bridge structure. The KMB215STR is a generally employed type of bridge rectifier which supports a peak forward surge current up to 40A and operating, forward voltage at 50℃ up to 200V. It is a full wave rectifier, able to convert alternating current to direct current, which makes it suitable for use in many applications.

The working principle of the KMB215STR involves the four diodes ideally placed so that when the AC current is passed through their external terminals, two of the diodes are forward biased, allowing current to flow through, while the other two are reversed, creating a block to the current flow. Each of the diodes then radiates the electrical energy of the alternating input current, so that only a continuous DC output is generated. In other words, when the process is complete, both output terminals are in the same state and current keeps circulating between them.

This diode bridge is applicable in numerous types of consumers, ranging from household appliances to industrial electronics and high-frequency telecommunications systems. It is particularly suited for use in electrochemical processes and power supplies. One of the main uses of the KMB215STR is for detecting electric motor overload in a motor overload control. In this application, current through the bridge rectifier transformer is sensed and a relay is energized to indicate an overload situation. Furthermore, it can also be used in a wide variety of applications such as switching power supplies, welding machines, small household appliances, electric drills and other electronic equipment.

The KMB215STR is also able to serve general purpose rectification purposes due to its relatively low price and its standardised mount- and form-factor. Its four separate diodes provide a significant advantage over single-chip diodes in that it allows asymmetrical load current flows which can be used to direct the power flowing through the system. This prevents power losses and lowers noise and electromagnetic interference. Furthermore, this bridge rectifier has the benefit of excellent maximum peak load current, low forward drop voltage and low thermal resistance.

Ultimately, the KMB215STR is a highly efficient and cost-effective bridge rectifier that is widely utilized in a multitude of applications. It offers the advantages of reliable and efficient operation, simple installation and excellent surge current characteristics. Its simple construction, sturdy design and easy to install structure makes it suitable for a large number of applications. With the aid of fault protectors and current limiters, it is able to supply a high power level without overloading the associated electric motor, making it a preferred option for motor control systems.
