Diodes – Rectifiers – Arrays

VSKC320-12 is a high voltage rectifier array designed for use in many different applications. The device consists of three separate rectifiers in a single package, each with its own anode and cathode connection for easy assembly. The device is designed to have a compact physical footprint and is suitable for current handling up to 12A. It has a wide range of operating temperatures and long-term stability and is rugged enough for industrial and military applications.

The schematic symbol for VSKC320-12 is shown in Figure 1. It is a three-phase rectifier array with three anode and cathode pins. The first two anode pins (A1 and A2), directly connected to the 3-phase AC input, represent the first two diodes. The second two anode pins (A3 and A4), directly connected to the diode bridge rectifier circuit, represent the other two diodes. The cathode pin (C) connects all three diodes together.

The main advantages of using VSKC320-12 in application fields include improved efficiency due to its fast recovery time, regulation of the input voltage, and superior performance compared to single-phase rectifiers. Also, the device features soft-start, allowing a controlled conduction phase that increases efficiency and protection even in harsh operating conditions.

VSKC320-12 operates as a rectifier, which is a device that converts ac electricity into dc electricity. The device works by allowing current to flow in one direction and blocking current from flowing in the opposite direction. A rectifier is built of diodes which only allow current to flow one-way. In the case of VSKC320-12, the diodes are connected in a bridge circuit which allows for three-phase input. The alternating current (ac) enters the device and is converted into direct current (dc) as it passes through the diodes.

Figure 2 shows the internal schematic of the VSKC320-12. It consists of three diodes connected in reverse parallel configuration across the 3-phase input, forming the diode bridge circuit. The diode bridge rectifies the ac input, which is then smoothed using filter capacitors and a linear regulator, resulting in a regulated dc output voltage. The device can provide up to 12A of output current at a peak operating frequency of 1000kHz.

The wide operating temperature range and superior reliability of the VSKC320-12 make it an ideal choice for applications in industries such as telecom, automotive, consumer electronics, and industrial equipment. It is essential in power conditioning, power factor regulation and power management. The device is suited for both commercial and industrial applications due to its cost-effectiveness and high-reliability, which makes it an attractive solution for various applications.
