Universal Smart Power Module Concept with High-speed Controller for Simplification of Power Conversion System Design

Abstract

This paper proposes the modular power conversion systems based on an Universal Smart Power Module (USPM). In this concept, the Power Electronics Building Block (PEBB) is improved the flexibility and the expandability by integrating a high-speed power electronics controller, input/output filters among each USPM to realize the simplification of the power electronics design. The original point of USPM is that each power module operates independently because a high-speed power electronics controller is implemented on each power module. The power modules of PEBB are typically configured by the main power circuits and the gate driver. Therefore, the controller has to be designed specifically according to various applications although the advantages of PEBB are high flexibility and user-friendly. The contribution of USPM is the simplification of the system design including power electronics controller. On the other hand, autonomous distributed systems require the control method to suppress the interference in each module. In this paper, the configuration of USPM, example of the USPM system, and detail of the control method are introduced.
