The gate drive circuit or microcontroller is required to trigger the MOSFET switch in the converter. In the new proposed topology, a non inverting or positive output buck-boost converter is implemented for PV system of stepper motor application. The pulse width modulation (PWM) signals for two MOSFET switches in the converter circuit are generated from DSP TMS 320F28335. Depending on the solar panel input, the non inverted buck-boost converter charges the battery. The DC load like stepper motor run from the battery. The load voltage and load current are sensed and compared with the reference voltage. The microcontroller is less accurate and by using microcontroller the solar energy cannot be fully converted into electrical energy. In industrial operation for the accurate system working is and commercial application DSP is used and for same DSP is used for generation of PWM signals. For that only the accuracy is more in closed loop operation and this works in real time. In the proposed study the PWM signals are generated from DSP using load voltage and load current, and as compared to existing system the proposed study is better in terms of load & line regulation, efficiency as tabulated by experimental results. MATLAB will used to simulate the circuit.
