This Work focuses on control of power inverter tecnologies for connecting any possible DC energy system to a single-phase using a current mode voltage mode control CMVMC. In this way a CMVMC can control only one power inverter in two operation modes. In current mode the control inject the active power in the utility and voltage control keeping loads always on with energy from the alternative DC sources. When instaled near big centers the control will choose the correctily operation or current mode or voltage mode depend on if the utility is present or no. This advanced, robust control strategies can determine the maximum on-line limit current from the DC energy, without DC current component and also free of island operation. The feasibility of this new control was digitaly simulated and implemented in analogic way.
