RB085T-90 Application Field and Working PrincipleIntroductionThe RB085T-90 is a bridge rectifier made by Ohmite, a leading supplier of electronic components and devices. It is designed to facilitate switching between AC and DC supplies and can be used in applications such as industrial, medical, automotive, and military. The rectifier is constructed from an array of diodes, which form a single-phase full-wave rectifier circuit. In this article, we will discuss the different application fields of the RB085T-90, as well as the principles behind its functionality.Application FieldsThe RB085T-90 is a reliable and efficient bridge rectifier applicable in industrial, medical, automotive, and military operations. Its robust construction enables it to sustain heavy load currents with minimal voltage loss. It also features high surge current capabilities, meaning it can handle large spikes in current, such as those caused by motor start-ups.In industrial operations, the RB085T-90 can be used as part of a DC power supply circuit. In this application, it can convert AC power to DC power quickly and efficiently, and can handle the load currents associated with industrial equipment.In medical applications, the RB085T-90 can be used to provide an uninterrupted DC power supply for medical equipment such as life support systems. It can be incorporated into a specialized power supply, which would allow it to take alternative AC sources as well as DC sources.The RB085T-90 can also be used in automotive applications such as vehicle charging systems, engine ignition circuits, and electrical power steering systems. In the wake of heavy on-road loads, the rectifier can handle the current demands reliably and efficiently.Finally, it can also be used for military operations where it can provide uninterrupted power for communication and defense systems.Working PrincipleThe working principle of the RB085T-90 involves the use of an array of diodes connected in a bridge rectifier configuration. In this configuration, two opposite facing diodes are employed, wherein each diode conducts current in one direction only.When an AC voltage is applied, the circuit allows current to flow in one direction only, while blocking current flowing in the other direction. This phenomenon is known as rectification, and its purpose is to convert the AC supply into a DC supply suitable for use in DC circuits.In order to increase the efficiency of the rectifier, both the array of diodes and the resistors are connected in a way as to minimize voltage losses. In addition, the use of filter capacitors helps to suppress voltage ripples in the DC supply, allowing it to have a smooth and consistent output.ConclusionThe RB085T-90 is an ideal solution for applications requiring a reliable and efficient bridge rectifier. It is constructed from extremely robust materials, allowing it to handle heavy load currents with minimal voltage loss. It is also capable of providing an uninterrupted DC supply for a variety of applications, including industrial, medical, automotive, and military operations. Finally, its reliable and efficient functioning is based on the principles of rectification, whereby an array of diodes is connected in a bridge rectifier configuration and resistors and capacitors are used to reduce voltage losses and to filter out voltage ripples.
