Objectives: This study is to introduce the design and development of a closed loop voltage-controlled forward converter operating in continuous conduction mode. Methods: The open and closed loop simulation was done in PSIM and the four different compensators were designed. Experimental work was carried out for both open and closed loop converter incorporating a type-2 PI compensator. Findings: A PI compensated forward converterwas capable of stepping down voltage with low ripple content and improved steady state performance. Application: The forward converter was designed in a laboratory prototype to study its operation for open loop and closed loop feedback. PI compensated forward converter was found to reduce the steady state error of the converter.
