Abstract : This paper deals with a switched boost inverter based dc nano grid. A battery is also interfaced with the grid such that in the absence of source, the battery will be used to supply the load. Switched Boost Inverter (SBI) is a buck-boost type hybrid converter derived from Inverse Watkins Johnson (IWJ) Topology. This converter can supply both DC and AC loads simultaneously which makes it suitable for DC nanogrid applications. For the working of SBI, it utilizes shoot-through state of the inverter bridge. So, the traditional Pulse Width Modulation (PWM) techniques of Voltage Source Inverter (VSI) have to be modified to incorporate the shoot-through interval in each switching cycle, so that they are suitable for SBI[3]. This paper discuses the PWM control strategy developed for SBI and proposes a novel technique for implementing the same using MATLAB Simulink A bidirectional converter is also developed to interface the battery with the dc grid.
