Application specific IPM for low power-end motor drives

Along with the rise of need for global energy conservation, the inverterization in the power electronics field is progressing quickly. In the area of low power motor control also, inverterization has become an indispensable choice, since it corresponds to ensuing regulations related to the Earth's energy preservation. However, in this low power area the cost of inverterization has to be justifiable and, so, optimization of total-cost-performance ratio has become very important. This time, paying attention to low capacity motor drive, a new series of intelligent power modules (IPM) called the ASIPM (Application Specific IPM) covering 0.1 kW through 1.5 kW drive capability has been developed. These devices contribute further miniaturization and higher performance features to its application systems. As these devices have been developed through various process of optimization related to IGBT chip, free-wheel diode chip, main controller HVIC circuitry and process technologies, packaging structure, etc., these promise high-level cost-to-performance feature to the next generation application systems. This paper explains the aspects of internal system design and key-technologies involved together with numerous functions and features of the new ASIPM series.
