Abstract In this paper, a novel drive power supply framework for power electronics devices is presented. It is used in the applications where medium-high voltage electric insulation is required. The novel framework is based on the concept of series ac bus and employs high tension cable and optical fibre as insulation media to achieve excellent multiple output and high-voltage insulation performance. And a novel series current ac bus is developed. First, the whole system structure and its characteristics are shown and described. Secondly, each module of the system is discussed in detail, and functional requirements and design criteria are proposed, and some solutions are provided, compared and also evaluated for reference. Finally, a 400W prototype was built to verify the feasibility of the novel framework. The theoretical analysis and experimental result show that the drive power supply based on the standard for reference in the paper is of the advantages of simple structure, high reliability, improved conversion efficiency and transmission efficiency, and can be used to drive different kinds of semiconductor devices.
