Designed, Built, Tested
Board pictured here has been fully assembled and tested.
Overview
Description
The transformer provides a galvanic isolation of 1500VRMS between the primary and the secondary. In addition, an optocoupler is used to provide secondary side feedback to the controller for voltage regulation while maintaining isolation. This document also discusses a step-by-step procedure that is used to implement this reference design. Design equations for the calculation of all the design parameters are presented. These equations show how the component values were calculated enabling users to modify this design for their applications.
