VDI75-12P1 application field and working principle

The VDI75-12P1 is an Insulated Gate Bipolar Transistor (IGBT) module developed by the renowned VDI Inc in Seoul, Korea for industrial applications. It has a rated current of 75A and a collector-emitter voltage of 1200V.

The module provides a high dielectric strength of 600V, high power dissipation rate of 260W, low output capacitance of 27nF, and low switching losses of 0.75ns. This makes it suitable for high power applications such as converters, inverters, rectifiers, and drives.

The VDI75-12P1 is designed to withstand a wide range of operating temperatures of -20°C to +125°C. In addition, it has a truly isolated design with a built-in high speed IGBT driver for increased safety and reliability. The module is UL recognized for both high temperature of up to 200°C and high current insulation level.

The VDI75-12P1 module is based on a non-punch through (NPT) IGBT which is much faster in switching than conventional punch through (PT) IGBT devices. This higher switching speed reduces the switching losses and increases the power efficiency of the power electronics system.

The IGBT module’s working principle is based on the principle of reverse current flow. When the gate is closed, current flows from the collector to the emitter. When the gate voltage is increased, it inverts the current flow from the emitter to collector. This connection is used to produce an AC or DC output from the IGBT.

The VDI75-12P1 module is widely used in a variety of industrial applications such as inverter drive systems, solar inverters, UPS systems, variable speed drives, and ac/dc converters. It is able to provide high speed switching and high stability for these applications. In addition, it is suitable for applications that require high current density in a small mounting area.

In conclusion, the VDI75-12P1 IGBT module is an ideal choice for those looking for a reliable and efficient solution for industrial applications involving the conversion of high voltage or current. With its high switching speed, high power dissipation rate, and UL certification, the module is able to meet the demands of these applications.
