This paper presents the development of a multi-input multi-output bi-directional power converter (MIMO-BDPC) with a digital pulse-width modulation (DPWM) controller for solar photovoltaic (SVP) application. The converter is operated in three modes such as buck, boost, and inverter. The converter uses a minimum number of active components and the DPWM controller controls the switching frequency or pulse period which are reconfigurable for effective synchronous and autonomous operation. The autonomous mode is selected by the controller based on the availability of the power source. The combination of high performance, low cost, and high reliability in a single controller is achieved via this intelligent digital approach. The controller is based on the power and load changes in multiple PWM modes. The Intel Altera Cyclone IV FPGA control will be used for digital PWM. The FPGA is scheduled for parallel data processing with multiple resource blocks. During control, this controller can be reprogrammed dynamically again. This makes the system extremely efficient in the check aspect, reducing time and cost. The proposed MIMO-BDPC is tested with the above-mentioned modes of operation using MATLAB software and also through hardware results.
