VI20120C-M3/4W

VI20120C-M3/4W Application Field and Working Principle

As a type of rectifier array, the VI20120C-M3/4W is an advanced full-wave diode bridge rectifier and includes 3 high-performance Schottky diodes with 4-terminal configuration. This type of rectifier array builds a portable, low-cost direct current (DC) voltage regulator. It is suitable for many ultra-high frequency and high voltage applications, such as switching power supply, ballasts for lighting and control circuits.

This rectifier array has two switches which are built-in, a bipolar switch with a high off-state resistance, and a unipolar switch with a low off-state resistance. This helps ensure the accuracy and stability of the input current and output voltage when the power supply is connected and the voltage is adjusted. It also provides higher efficiency and better reliability due to its guarding and robust performance under harsh conditions.

Working Principle of VI20120C-M3/4W rectifier array

VI20120C-M3/4W rectifier array utilizes the principle of full-wave rectification to convert AC electricity into DC electricity. Its operation relies on the rectifying effect of three high-performance Schottky diodes and the switch built-in. When the input AC voltage is applied to the Schottky diodes, one of the Schottky diodes conducts current and the other two diodes are blocked, forming a forward-biased diode (which allows current to flow through from its anode to its cathode) and two reverse-biased diodes (which prevents current from flowing in opposite direction). At this point, the voltage across the forward-biased diode drops, allowing current to flow through the load. This ultimately results in a full-wave DC output voltage.

When the switch is activated, the bipolar switch connects the input voltage to the bridge rectifier. This produces an output voltage. Then the cycle of operation repeats itself, the current moving in an alternating direction each time. When the unipolar switch is closed, the rectifier array is effectively connected to a voltage source thus allowing the output voltage to be adjusted for optimal operation.
