This paper presents the design of an Internal Model Control – 1 Degree of Freedom (IMC-1DOF) controller applied to a Zero Voltage Switching (ZVS) Full-Bridge DC-DC converter that will be used in photovoltaic systems for Maximum Power Point Tracking (MPPT), with the objective of developing a single phase micro inverter. It will be presented the mathematical modeling of this converter to control the input voltage aiming the application in MPPT and the design of the respective controller IMC-1DOF. The proposal testing and validation strategy was performed by comparison with a PI compensator. The performance of both controllers are evaluated and discussed.
