Appliance Design - January 2009 - (Page 41) MOTORS Optimized Power Package lacing power control electronics on printed circuit boards provides a great deal of design flexibility, while attaching power semiconductors to a substrate delivers excellent thermal properties for motor drives. Designers of such drives can now reap the benefits of both approaches in a recently developed intelligent power module. The Control Integrated Power System (CIPOS™) combines these features in a single, molded module. The low-cost component makes it suitable for high-volume, consumer product drive applications, such as appliances employing inverter drives. This approach is made possible by pairing state-of-the-art IGBT performance with the ability to easily customize the functionality of the module, ultimately allowing a shortened development cycle with an optimized, low-cost design. A typical motor design project faces several constraints, including a tight project schedule, budget or tooling cost limitations, and a www.applianceDESIGN.com P demanding technical specification. The conventional discrete solution that employs a separate IGBT and diode chip takes up to three times as much assembly area as a molded module. CIPOS makes it possible to move to the smaller form factors of intelligent power modules and maintain the advantages of Infineon’s power semiconductor technology. Fig. 1 shows the optimized package outline. Internally, two different carrier materials are used: The green colored common printed circuit board (PCB). A common direct copper bonded substrate (DCB). The PCB carries the control components that are integrated in the module. This includes the gate drive integrated circuit, the gate resistors, the external circuitry for the gate drive IC, and the bootstrap circuit of each high-side supply with capacitances of 100 nF each. A Module increases output and flexibility in inverter drives. by peter stipan and wolfgang frank Peter Stipan is sales, marketing, and business development manager, Infineon Technologies, Wind Lake, Wis., and Wolfgang Frank is concept engineer, Infineon Technologies, Munich, Germany. applianceDESIGN January 2009 41 http://www.appliancedesign.com
