.Diodes - Bridge Rectifiers: KBU8D Application Field and Working Principle
Bridge rectifiers are the simplest circuits for converting the alternating current (AC) input to a steady direct current (DC) output. These rectifiers find application in a variety of electronic devices, such as power supplies, motors, and machines. Additionally, they are used as voltage rectifiers in switch mode power supplies (SMPS). KDU8D is a general purpose single phase 500W bridge rectifier. This article explores the application field and working principle of this rectifier.
Application Fields of KBU8D Bridge Rectifier
The KDU8D bridge rectifier is a general purpose device designed to offer DC conversion from AC sources of 50Hz, 60Hz, 400Hz, and 1000Hz. The input voltage range of the bridge rectifier is from 5 to 26VDC. The peak output current of the device is 8A and its average forward current is 0.5A. It has a load regulation of 5% and a ripple voltage of 100mV RMS. The rectifier has a thermal resistance of 1.3°C/W, a dielectric strength of 600Vrms, and an insulation resistance of 10MOhms.
Due to its high input and output characteristics, the transformer bridge rectifier is suitable for use in applications such as power supply for UPS, battery charger, motor speed control, lighting source, and motor drivers. It can also be used in voltage multiplier circuits, impulse switching, telecommunication systems, and in various other industries.
Working Principle of KBU8D Bridge Rectifier
As a bridge rectifier, the KDU8D operates on the principle of the four-diode network that is connected in a bridge configuration to form a closed loop. This configuration gives four possible combinations of two diodes such that each one will conduct current in the circuit during one quarter of the input AC signal.
During a signal cycle, the output voltage of the bridge rectifier is a positive half-cycle signal. During this signal cycle, two of the four diodes are forward biased and will conduct current, while the other two diodes remain reverse biased and will not conduct current. The two forward-biased diodes will allow the current to flow during the positive half cycle of the AC signal.
For the negative half cycle of the AC signal, the opposite occurs: the reverse biased diodes will conduct current and the forward biased diodes will not. During this negative half cycle, one diode conducts current in one direction, while the other diode conducts for the opposite direction. Hence, by combining the two directions, a unidirectional current from the AC signal is created.
Since the KDU8D can support input AC frequencies of up to 1000Hz, it can also be used for high frequency applications such as motor control, robotics, and other motion control systems.
Conclusion
The KDU8D bridge rectifier is designed to offer DC conversion from AC sources of 50Hz, 60Hz, 400Hz, and 1000Hz. It is suitable for use in a range of applications such as power supply for UPS, battery charger, motor speed control, lighting source, and motor drivers. The rectifier operates on the principle of the four-diode network that is connected in a bridge configuration to form a closed loop.
