Abstract

This paper presents the design of an output-series active-clamp flyback high-voltage power supply. By utilizing an output-series connection, the voltage stress on rectifying diodes is reduced. Active-clamp technique is adopted to address issues such as reduced efficiency and high voltage stress on the main switch, which are caused by increased leakage inductance in the transformer due to insulation requirements of high-voltage outputs. The operational principles and design considerations of the converter are introduced, with particular attention given to the transformer's electric field distribution. A prototype is built to validate the feasibility of the system design.
