Complex circuitry of electronic infrastructure of compact smart micro grids with multiple renewable energy sources feeding the loads using parallel operation of inverters acts as a deterrent in developing such systems. Parallel Inverters is one of the best methods to provide great load power. One way of briefing electronic infrastructure of micro grids, use parallel driver circuit focusing on bootstrap techniques. But so far research has been done in this area that if fault occurs in the switches what happens and will provide the reliability of the driver circuit? In this paper, first the parallel inverter and its driver circuit are studied and in the next section, their behavior will be analyzed when the switch is erroneous. Digital Simulation in Matlab Simulink is used to show the proposed solutions to this type of behavior and to avoid errors leading to other parts of the system.
