This paper presents the design and development of 20 W, 200–400 V, secondary regulated closed loop multi-output flyback converter. It discusses the design procedure, calculations and a noise reduction technique to improve the converter regulation. The flyback provides isolation between different auxiliary supplies that are required for operation of ICs, sensors, controller, top side switching of converters, etc. These circuit components require constant supply voltage irrespective of the changes in load and input voltage. The paper implements closed loop flyback converter using PWM IC UCC28C44DR along with opto-isolator LIA130S to provide constant voltage.
