This paper presents a novel scheme of a multi‐output power supply for solid‐state switches based on series‐connected semiconductor devices. By using the loosely transforming method, the system can realize high‐voltage isolation and a compact size, and its application range can be easily expanded to modular designed switch stacks for higher power ratings. The circuit structure and working principles are described. Based on the system operating equations, the design methodology is proposed and applied for parameter specification of a power supply system of two series‐connected switch stacks containing 20 outputs. Detailed calculations are given, and experimental results prove the feasibility of the proposed scheme. © 2017 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
