High Performance Intelligent Power Modules Using CSTBT Chips with Integrated Temperature Sensor

摘要

This paper describes a new family of intelligent power modules featuring the latest IGBT chip technology. These modules are targeted for all motor drive applications including general-purpose drives and multi-axis servo drives. The new IPMs feature compact packages designed for convenient installation. Fifth generation CSTBT (Carrier Stored Trench Bipolar Transistor) IGBT chips are utilized to provide low switching and conduction losses. The new chips are fabricated with an advanced on-chip temperature-sensing feature to provide effective over temperature protection against severe operating conditions. A new control circuit topology reduces EMI.
