Introduction

The BSM400GA170DLCHOSA1 is an insulated gate bipolar transistor (IGBT) module. It is a kind of combination of IGBT and diode, with both the switching functions of MOSFET and the fast switching speed of bipolar transistor. This module can provide output current of 400A and blocking voltage of 1700Vct. Its high-current carrying capacity and low loss makes it ideal for traction inverters, UPS, wind and solar energy systems, traction converters, and various motors.

Basic Principles

The working voltage of the BSM400GA170DLCHOSA1 module is based on the principle of PN junction. This junction is formed by connecting two P-type and N-type semiconductors. In the working circuit, when the bias voltage is applied, the electric field generated will move electrons from the n type side to the p type side to form a space charge layer at the junction when electrons and holes combine; and these charges can form an electric current. In this process, the electrons present on the p-type side will become excess and cause the p-type semiconductor to become positively charged and the n-type semiconductor to be negatively charged. As a result, an electric field will be formed. This electric field will repel any negative charges that enter the junction, and attract any positive charges that enter the junction, creating a semiconductor diode.
