Diodes - Bridge Rectifiers

A bridge rectifier is a device that uses four or more diodes in a bridge circuit configuration to convert alternating current (AC) to direct current (DC). It is one of the most commonly used diode configurations and is widely used in power conversion circuits. Bridge rectifiers are particularly useful in AC-to-DC power supply applications because they can provide full-wave rectification with a single component that can withstand high voltages.

KBP2005-BP is a bridge rectifier that is widely used in various applications, such as battery chargers, inverters and rectifiers, AC motors, and UPS power supplies. It is composed of four main components: two main diodes, two short-circuit diodes (KBP2005-BP1) and a surge protection diode. The two main diodes are the primary components responsible for rectifying AC current to DC, while the two short-circuit diodes are used to protect the rectifier from over current in case of a short circuit. The surge protection diode is used to protect the bridge rectifier from transients and over voltages.

The working principle of the bridge rectifier is simple yet effective. When an alternating current is applied to the two main diodes, the positive half -cycles of the AC signal passes through one diode while the negative half-cycles of the AC signal passes through the other diode. This current flow creates a DC current output from the bridge rectifier. The two short-circuit diodes provide a parallel current path when a short circuit is detected, allowing the current to bypass the rectifier and preventing potential damage. The surge protection diode limits the peak voltage across the bridge rectifier, thus providing protection from transients and over voltages.

KBP2005-BP bridge rectifier is suitable for high voltage applications with a peak repetitive reverse voltage of 400 volts (Vrrm) and a non-repetitive peak forward surge current of 32 amps (I(Fsm)). It also features low leakage current of 10mA and a junction temperature of 105°C. Furthermore, it is designed with a lead-free silicone casing that provides protection against dust, corrosion, and other environmental hazards. To ensure safety and reliability, customers must use the device in accordance with the specified operational conditions and parameters.

In summary, the KBP2005-BP bridge rectifier is a suitable power supply component for various applications due to its high voltage and surge protection capabilities. By harnessing the full-wave rectification technology of the bridge rectifier, customers can benefit from reliable DC power and protection from potential damage caused by current overload and voltage transients.
