MUR550PF Application Field and Working Principle

MUR550PF belongs to a type of diode widely-used in different electronic fields, namely, single rectifier. A rectifier is a device that uses voltage to convert alternating current (AC) to direct current (DC), and supplies the electric power with the most suitable form to the devices. It is made up of a diode, resistor and capacitor, forming the three terminals. The inner structure of single rectifier is composed of only one diode in common, hence the name. Nowadays, diodes become even more useful and important due to the development in various electronics devices. MUR550PF is one of the commonly used rectifier diodes.

MUR550PF has wide application field with several outstanding features. It’s often used to the AC/DC transformer which can ease the rectifier waveform distortion and reduce the volume. It fits the appliances in heat induction heating range, electric cooking utilities and conversion power used in magnetic drive. Besides, it can also be applied to the airport lighting, ups and other related products.

As regards its working principle, when AC runs through the diode, the electric current runs freely in one direction and so AC is converted to DC. Firstly, applying AC voltage to the input end, and makes it pass through the resistor and capacitor, then it flows into the diode. The rectifier diode restricts the current in one direction and acts as a one way gate to pass the AC current and block the reverse current, then the output is DC. The resistor and capacitor can filter out the high frequency harmonic, so that the output of DC is pure and without any noise. In addition, those two components can form a compounding circuit for improving the DC voltage limited value, thus assuring the stability of the output DC.

As a summary, MUR550PF belongs to single rectifier, featured to have wide applications, such as AC/DC transformer, induction heating appliances and driving power, also airport lighting. Working principle-wise, the AC current is converted to DC under the action of the rectifier diode and resistor, capacitor filter the high frequency harmonic, so that the output DC can be pure and stable.
