Abstract (Original Language): 
In this research article we have proposed a new analog MPPT regulator with the high efficiency DC-DC converter for the photo voltaic and high efficient z- source converter for the variable speed wind energy systems. The both renewable energy output power is connected in parallel with the diesel generator and whole system provide the efficient hybrid energy systems to given the electrical power to the external grid. The MPPT regulator provides the control signal for the DC-DC converter and tracks the maximum power from the solar panel. In which here a logic truth table based perturbation and observation (P & O) algorithm used for the maximum power point tracking (MPPT) and hybrid bridge resonant DC-DC converter is giving the constant output voltage equal to the DC bus voltage by changing the proper modes. The parallel configuration is selected for the energy transformation from the solar panel, wind power and diesel systems to the load. The design includes a bidirectional inverter along with a dc-dc converter capable of interfacing a battery bank with the AC bus. The goals of the project included the implementation of two modes of operation: a battery discharge mode where current is being fed into the AC bus and a battery charging mode in which current is pulled from the grid and put into the batteries. A secondary goal of the design was to ensure that the current being injected into AC bus was at or near unity power factor by utilizing a hysteresis current control method.
