Diodes are semiconductor devices that are widely used today due to their ability to reliably convert alternating current (AC) to direct current (DC). Bridge rectifiers are a very common type of diode and they are used to convert AC to DC. KMB28STR is one such bridge rectifier and its application field and working principle are discussed in this article.

KMB28STR bridge rectifiers provide high current ripple and fast pickup. They are designed to be used in electronic circuits, such as in automotive and industrial equipment, home appliances, and computers. They are capable of handling high currents, up to 25 amps, and are reliable, low cost, and easy to install.

The KMB28STR is a four terminal device with three diodes. This device is composed of two pairs of parallel-connected diodes, stacked in the same direction, and connected in series with the fourth terminal being the negative terminal. The two terminals of each pair are connected together and to the positive and negative terminals of the bridge rectifier. Thus, when AC power is applied to the bridge rectifier, the pairs of diodes will conduct current in the same direction, but alternately. The effect is that two AC waveforms are created in the output, one positive and one negative. This is because each pair of diodes will block the opposite waveform, while allowing the other one to pass.

The working principle of the KMB28STR bridge rectifier is based on the concept of a bi-directional switch. When an AC input is applied, the device will alternately open and close a switch to allow current to flow in the same direction from left to right and from right to left. This causes the negative half cycles of the AC waveform to be converted to positive half cycles of DC. This DC output can then be used in electronic circuits.

In addition to its traditional use in converting AC to DC, the KMB28STR bridge rectifier can also used for power factor correction, frequency conversion and voltage regulation. Power factor correction is the process of increasing the power factor by adding capacitors and inductors to the AC input. Frequency conversion is used to control the speed of a motor and other types of controlled loads. Voltage regulation is a process which keeps the voltage of an electrical system within specified limits.

The KMB28STR bridge rectifier is commonly used in many types of electronic equipment and applications. It is a cost-effective component that provides a reliable source of DC power when AC input is available. It is an efficient device that converts AC to DC with minimal power loss, making it an ideal choice for a variety of AC to DC conversion applications.
