Specific problems in smart power design

In this paper the following problems: selection of the power device and driving circuit, sensing and protection circuits, transmission of the sensor signals, thermal problems in smart power module, and simulation problems of the smart power modules design are presented and discussed. The deliberations are illustrated with the example of a PWM converter circuit designed in Mietec HBiMOS 2 /spl mu/m technology. The new electro-thermal practical model of transistors which can be used in complex electro-thermal simulation of a smart-power structure is presented.
