DF650R17IE4BOSA1 is a module of the 6th IGBT Generation, manufactured by Infineon, that belongs to the family of Transistors - IGBTs – Modules. It is a common-source N-channel MOSFET insulated gate bipolar transistor module with enhanced robust, for automotive applications and is ideal for use in traction inverters. The DF650R17IE4BOSA1 is a high power density module, with a reverse surge power rating of 150A and a turn-off voltage of 650 V, it can be used to regulate, switch and render power without the heat sinks and supports, in an easy fashion.

This application field and working principle ofDF650R17IE4BOSA1 can be broken down by its usage in automotive applications. This module is mainly used in train, car, or bus’ traction inverters. It is designed as a simple and stable power converter that can quickly provide the required power to vehicles. On a basic level, when a driver hits the accelerator pedal, a signal is sent from the ECU (Engine Control Unit) to the traction inverter, which then starts converting the DC power supplied by the battery, to AC power for the electric motor.

So what is an IGBT? The IGBT stands for Insulated Gate Bipolar Transistor and is a combination of both MOSFET (metal oxide semiconductor field-effect transistors) and bipolar transistors. It has the low-drive input of a MOSFET and the high-speed switching of a bipolar transistor. So with its combination of features, IGBTs are designed to take the best of both worlds and behave as a combined fast switching, low-power loss MOSFET.

Now let\'s focus on the working principle of the DF650R17IE4BOSA1 module. When used in a traction inverter, the DF650R17IE4BOSA1\'s working principle can be divided into four stages. The first stage is the On stage, which is when the current flows from the output side to the ground and power is supplied to the electric motor. The second stage is the Off stage, where the current no longer flows between the output and the ground and is instead diverted through the body diode of the module. The third stage is the Recovery Stage, where the current no longer flows through the body diode and the module is returned to its originating state. The last stage is the Short Circuit Stage, which is when a short circuit occurs between the output and the ground.

The DF650R17IE4BOSA1’s application fields and working principle allows it to deliver the power required to vehicles without the need of heat sinks and the supports, in a very efficient manner. It provides a reliable, safe and stable power conversion which is ideal for automotive applications and is an essential part of the traction inverter. Therefore with its reliability, efficiency and durability, the DF650R17IE4BOSA1 module will definitely be a great addition to any project related to automotive applications.
