AC DC Converters

RTW285R4 Application Field and Working Principle

RTW285R4 is an AC DC converter that offers a power supply for a variety of modern appliances. This converter is convenient to use, simple in design, and features a low input voltage range to ensure reliable current output. RTW285R4 can also be used in a variety of power supplies and is widely applied in electric vehicle, instrumentation, and industrial automation equipment.

Working Principle of RTW285R4

The RTW285R4 works by converting alternating current (AC) to direct current (DC). The power supply uses a bridge rectifier to convert the AC input to DC. The bridge rectifier is composed of four diodes which provide a full wave rectification. After the rectification process, the current is stored in capacitor. The input voltage of the converter is then converted to a specified DC output voltage via a DC-DC switching circuit.This switching circuit uses the properties of a transformer (switching frequency) to reduce the amplitude of the input voltage. The frequency of the switching circuit is controlled by a frequency control device that monitors the input voltage wave, and adjusts it accordingly. The DC output voltage is regulated by an integrated circuit and output filter. This output filter is responsible for removing the switching noise from the output voltage of the converter.
