Abstract

This paper presents an offline AC/DC converter with digital control and galvanic isolation that can be implemented using cheap commercially available components. An ATMEL ATTiny26 8-bit microcontroller is used to control the converter. The microcontroller is placed on the secondary side of the converter and an analogue primary side startup controller is used on the primary side. A prototype two-switch forward converter has been designed and experimental results are included to show the feasibility and performance of the proposed design.
